BACKGROUND
[0002] 1. Field
[0003] The invention relates to computer networks. In particular,
the invention relates to managing network server
configurations.
[0004] 2. Description of Related Art
[0005] Explosive growth of the Internet, and in particular
e-commerce, has resulted in a dramatic increase in the rate at
which companies and individuals are creating network resources such
as World-Wide-Web sites, email accounts, and the like. Most
companies do not have a direct connection to the Internet and thus
contract with a web hosting company, or Internet service provider
(ISP), to provide access to the Internet and to host the resources
they wish to make available to other Internet users.
[0006] Typically a web hosting service provider may provide a wide
range of e-commerce, application hosting, and connectivity
services. For example, a company or individual may contract with a
web hosting company to provide a specified amount of memory on a
server for the company to establish and maintain its web site. In
addition, the company may contract for other types of services,
such as, for example, email services, secure socket layer (SSL),
file transfer protocol (FTP) service, database services, and real
media service allowing streaming audio and video from the company's
web site.
[0007] After a company or individual has established its initial
set of services with a web hosting service provider, they may wish
to change the services it has contracted for. For example, if the
company had not originally contracted for real media service, it
may wish to add this feature to its web site. Typically, when a
company wants to change the services it has contracted for, a
request for the desired change would be communicated to the web
hosting service provider. At the web hosting service provider, a
system administrator would determine if the new services are
available to the requesting company and which network servers of
the web host's system should be configured to accommodate the
requested configuration. The system administrator would then access
the appropriate server and change the server configuration to
conform to the requested change. In some instances, accessing the
appropriate server may require the system administrator to travel
to a remote site where a server is located. At some facilities,
this process was partially automated by programming the servers
with scripts that performed some tasks of the configuration
process. However, administrator access to the server was still
required to implement the configuration changes.
[0008] In addition, web hosting service providers must maintain
accurate records of the server configurations. The records of the
server configurations allow the web hosting service provider to
monitor equipment utilization to help determine, for example, when
increased customer demand would justify upgrading existing
equipment, or bringing additional equipment on line. Accurate
records are also required to ensure proper billing of companies
contracting for the services provided. To both maintain server
configurations according to customer desires, and to simultaneously
track server configurations as they are altered over time, a system
administrator would both update server configurations and also
update a database containing information regarding server
configurations. Requiring the system administrator to update a
database is prone to errors in the entry, as well as inadvertently
failing to record a configuration change that was made.
[0009] Therefore, there is a need in the art for a method and
apparatus to improve the speed and efficiency of matching server
configurations with customer desires. In addition, there is a need
in the art for a method and apparatus to improve the recording and
monitoring of network equipment configuration.
SUMMARY
[0010] In one embodiment, the invention comprises a method of
synchronizing configuration parameters on a server with a database
of stored configuration parameters comprising automatically
updating the configuration parameters on the server in response to
updating the database of stored configuration parameters. Systems
for processing information are also provided. In one embodiment,
such a system comprises a plurality of network servers having
application programs running thereon, the application programs
comprising configuration parameters defining at least some aspect
of application program operation, and a database storing at least
some of the configuration parameters. In this embodiment, a
communication link connecting the database to the plurality of
network servers is provided to transfer the configuration
parameters to the plurality of network servers.

DETAILED DESCRIPTION
[0024] Embodiments of the invention will now be described with
reference to the accompanying Figures, wherein like numerals refer
to like elements throughout. The terminology used in the
description presented herein is not intended to be interpreted in
any limited or restrictive manner, simply because it is being
utilized in conjunction with a detailed description of certain
specific embodiments of the invention. Furthermore, embodiments of
the invention may include several novel features, no single one of
which is solely responsible for its desirable attributes or which
is essential to practicing the inventions herein described.
[0025] FIG. 1 shows an exemplary computer network 10 connecting one
or more computing machines. The network 10 may be any type of
electronically connected group of computers including, for
instance, the following networks: Internet, Intranet, Local Area
Networks (LAN), Wide Area Networks (WAN) or an interconnected
combination of these network types. In addition, the connectivity
within the network 10 may be, for example, remote modem, Ethernet
(IEEE 802.3), Token Ring (IEEE 802.5), Fiber Distributed Datalink
Interface (FDDI), Asynchronous Transfer Mode (ATM), or any other
communication protocol. Computing devices linked to the network may
be desktop, server, portable, hand-held, set-top box, personal
digital assistant (PDA), a terminal, or any other desired type or
configuration. Depending on their functionality, the network
connected devices may vary widely in processing power, internal
memory, and other performance aspects. Communications within the
network and to or from the computing devices connected to the
network may be either wired or wireless. Wireless communication is
especially advantageous for network connected portable or hand-held
devices. The network 10 may include, at least in part, the
world-wide public Internet which generally connects a plurality of
users in accordance with a client-server model in accordance with
the transmission control protocol/internet protocol (TCP/IP)
specification. A client-server network is a dominant model for
communicating between two computers. Using this relationship, a
client computer (the "client") issues one or more commands to a
server computer (the "server"). The server fulfills client commands
by accessing available network resources and returning information
to the client pursuant to client commands. During this process,
client computer systems and network resources resident on the
network servers are assigned a network address for identification
during communications between elements of the network.
Communications from other network connected systems to the servers
will include the network address of the relevant server/network
resource as part of the communication so that the appropriate
destination of the data/request is identified as the recipient.
When the network 10 comprises the global Internet, the network
address is an IP address in the TCP/IP format which may, at least
in part, route data to an e-mail account, a web-site, or other
Internet tool resident on the server. In this way, information and
services which are resident on the network servers may be available
to the web browser of a client computer through a domain name (e.g.
www.site.com) which maps to the IP address of the network
server.
[0026] As shown in FIG. 1, a plurality of clients 12, 14, and 16
are connected to the network 10 via respective communication links.
Typically, each of these clients may access the network 10 via any
desired form of communication, such as via a dial-up modem
connection, cable link, a digital subscriber line (DSL), wireless
or satellite link, or any other form of communication. Each client
may communicate using any machine that is compatible with the
network 10, such as a personal computer (PC), work station,
dedicated terminal, personal data assistant (PDA), or other similar
equipment. The clients 12, 14, and 16 may or may not be located in
the same geographical area.
[0027] As shown in FIG. 1, a plurality of servers 22, 24, and 26
are connected to the network 10 to serve clients that are in
communication with the network 10. Each server is typically a
powerful computer or device that manages network resources and
responds to client commands. As is known in the art, the servers
include computer readable data storage media such as hard disk
drives and RAM memory that store program instructions and data.
Using such stored programs, the servers 22, 24, 26 run application
programs that respond to client commands. As shown in FIG. 1, for
example, the server 22 may run a web server application for
responding to client requests for HTML pages. It may also run a
mail server application for receiving and routing electronic mail.
Other application programs, such as an FTP server or a media server
for streaming audio/video data to clients may also be running on
the server 22. In some cases, different servers may be dedicated to
performing different tasks. For example, the server 22 may be a
dedicated web server that manages resources relating to web sites
for various users, whereas the server 24 may be dedicated to
provide electronic mail (email) management. Other servers may be
dedicated for media (audio, video, etc.), file transfer protocol
(FTP), or a combination of any two or more services that are
typically available or provided over a network. Each server may be
in a location that is the same as or different from that of other
servers. Moreover, there may be multiple servers that perform
mirrored tasks for users, thereby relieving congestion or
minimizing traffic directed to and from a single server. In one
embodiment of the invention, the servers 22, 24, 26 are under the
control of a web hosting provider in the business of maintaining
and delivering third party content over the network 10.
[0028] Web hosting providers deliver services to two different
types of clients. One type, referred to herein as a "browser",
requests content from the servers 22, 24, 26 such as web pages,
email messages, video clips, etc. A second type of client, referred
to herein as a "user", hires the web hosting provider to maintain a
network resource such as a web site, and to make it available to
browsers. Users contract with the web hosting provider to make
memory space, processor capacity, and communication bandwidth
available for their desired network resource, generally paying the
web hosting provider in accordance with the amount of server
resources the user desires to utilize.
[0029] In order for the web hosting provider to provide services
for both of these clients, application programs which manage the
network resources hosted by the servers must be properly
configured. The program configuration process generally involves
defining a set of parameters which control, at least in part, the
application program's response to browser requests and which also
define, at least in part, the server resources available to a
particular user. In conventional web hosting environments, only
network administrators associated with the web hosting company that
owned the servers 22, 24, 26 were allowed access to the application
program parameters to change application program operation so as to
modify, for example, the amount of storage space allocated to a
given user's web site. This helped insure tight control of the web
hosting service provider over application program configuration.
However, all user requests for new server resources or a
reconfiguration of their existing resources required human
intervention, which is slow and relatively expensive.
[0030] In one embodiment of the invention, however, the user is
provided access to application program parameters in a manner which
still ensures adequate control over program configuration by the
web hosting service provider. In one embodiment, an intranet server
30 is in communication with the network 10 via a communication
link. The intranet server 30 is in communication with a server
manager 32. The server manager 32 comprises a database of the
application program configuration parameters which are being
utilized in the servers 22, 24, 26. In this embodiment, users
modify the database 34 via the intranet 30, and the server manager
32 interacts with the servers 22, 24, 26 to modify application
program parameters so that they match the content of the database.
In a typical operation, a user logs onto the intranet server 30 by
connecting to the intranet 30 via computer 12 and entering
authentication information, such as a username and password. An
example screen display for entering this information is provided in
FIG. 2.
[0031] In some advantageous embodiments, when the user wishes to
sign up for new service or modify an existing service, the intranet
server 30 authenticates the user (via the screen display of FIG. 2
for example) and provides the user with a interactive screen
display/control panel that allows the user to access configuration
parameters for a particular application program. One example of
such an interactive screen display is illustrated in FIG. 3. In
this embodiment, the user is presented with a number of modifiable
text boxes that describe aspects of the configuration of the user's
web site or other network resource.
[0032] For example, if a user desires to increase memory space
reserved on a server for its web site, the user is provided with a
"memory space" field 36 (FIG. 3) in which the user specifies the
desired memory space. In response to receiving this information,
the intranet server 30 updates the database 34. The server manager
32 forwards this information to the appropriate server, and the new
parameter is used during application program operation. Thus, the
intranet server 30 is configured to provide users with access to
configuration parameters of hosted network resources (e.g., web
pages, email, FTP sites, media sites, etc.), for which a user has
contracted with the web hosting service provider.
[0033] As will be described in additional detail below, the
configuration parameters may be stored in the database 34 in the
format of a plurality of tables. When the user modifies the desired
configuration parameter (e.g., memory space) for its web site, the
intranet server 30 communicates such modification along with user
identification information to the server manager 32. In turn, the
server manager 32 updates one or more tables that include this
parameter. Once the one or more tables are updated in the server
manager 32, the server manager 32 communicates one or more commands
to one or more of the servers 22, 24, and 26 indicating that the
one or more tables of the server manager 32 has been modified. In
one embodiment, the servers are configured to run a dedicated
program (e.g., a daemon) that is triggered to retrieve the modified
parameter from the updated table of the server manager 32. As is
known in the art, a daemon commonly refers to a process that runs
in the background and performs a specified operation at predefined
times or in response to certain events. After being triggered by
the server manager 32, the daemon updates the configuration of the
application program (e.g., web server) with the retrieved
parameter. One embodiment of this process is described in further
detail in the description of the processes of FIGS. 4-6. Generally,
the intranet server 30, server manager 32, and network servers 22,
24, 26 are all under the management and control of the web hosting
service provider. In some embodiments, these computers will be
located in a single facility and connected to a common local area
network. In other embodiments, these computers are widely separated
geographically and may communicate over the public Internet. The
computers 12, 14, 16, utilized by the users to access the intranet
30 will generally be geographically remote from the server manager
32 and the servers 22, 24, 26, although it will be appreciated that
one or more of these devices 12, 14, 16 may be directly connected
to the intranet 30 or other LAN which includes the server manager
32.
[0034] FIG. 4 is a flowchart of a method of updating a server
configuration. The process begins in block 40, where a centralized
database is updated with selected parameters to make the desired
change to the configuration of a selected application program. This
modification to the database may be made by a user, as described
above, or by a network administrator associated with the web
hosting service provider. After the centralized database has been
updated, flow continues to block 42. In block 42, a program
residing on a selected server, commonly referred to as a daemon, is
initiated or triggered. When the daemon program is triggered, it
will read the modified fields in the updated centralized database.
Flow then continues to block 44. In block 44, the daemon, using the
parameters from the modified fields of the centralized database,
will update or synchronize the server configuration with the
updated centralized database fields accordingly. In this way, a
database of server configurations is kept consistent with the
actual server configurations automatically and with little or no
human intervention.
[0035] FIGS. 5 and 6 are flowcharts illustrating a specific
embodiment of a method of modification of a server configuration in
response to a user request. Process flow begins in block 48. In
block 50, a user logs on to the web hosting Intranet server. In
block 52, user access to the Intranet server is authenticated. User
authorization may be determined through a set of criteria, or
"business rules." For example, user access may be denied if the
user does not have a valid account, or if the user is not current
in their account balance.
[0036] If user access is not authorized, flow continues to block
54. In block 54, user access to the web hosting Intranet is denied
and flow loops back to block 50. Returning to block 54, if user
access is authorized, flow continues to block 56. In block 56, the
user selects an application program parameter to change. For
example, the user may select a web server configuration application
program and request the amount of memory allocated to the user
website be modified, such as, for example, to increase the memory
allocated from 5 megabytes to 10 megabytes. In another example, the
user may select an email application program. For example, the user
may add new email accounts or delete existing ones. After the user
has selected the application program parameter desired to be
changed, flow continues to block 58.
[0037] In block 58, the application program parameter selected by
the user is checked to determine if it is a parameter the user is
allowed to modify. If the user has selected a parameter it is not
allowed to modify, such as, for example, attempting to modify a
service the user has not contracted for, flow continues to block
60. In block 60, the user is notified that the desired selection
has been denied. Flow then continues to block 58. If the user has
selected a parameter that is allowed to be modified, flow continues
to block 62. In block 62, the user modifies the selected parameter
as desired. In some embodiments, these process steps are
accomplished by routing a control panel to the user which only
allows the user access to those parameters the user is allowed to
change. Referring back to FIG. 3, for example, a web-site
modification control panel is illustrated which allows the user to
modify some aspects of host service but not others. As described
above, a space field allows the user to modify the space allocated
to the site. However, the host server that the site is resident on
and the associated IP address of the site are shown on the control
panel, but are not user modifiable. In block 64, the modified
parameter is communicated to the server manager. Flow then
continues to block 66. In block 66, the server manager evaluates
the modified parameter and determines which table or tables are
required to be updated in the server manager database. Flow then
continues to block 70 in FIG. 6.
[0038] In block 70, the server manager updates the tables in the
database with the modified parameters. In block 72, the server
manager determines which server to synchronize with the updated
database reflecting the user request. The server manager may
determine a single server configuration is to be updated, or that a
plurality of server configurations are to be updated, in response
to the user request. Flow then continues to block 74.
[0039] In block 74, the server manager instructs the desired
server, or plurality of servers, to update their configuration
settings. Typically, updating of server configuration settings is
performed by a server resident program, such as, for example, a
daemon program as described above. Flow then continues to block
76.
[0040] In block 76, the server being reconfigured determines if it
can accept the instructions and reconfigure itself in the desired
manner. For example, if a request of additional memory for a web
site is received by a server, the server will determine if there is
sufficient memory available to perform the desired reconfiguration.
If the server is unable to accept and perform the instructions,
flow continues to block 78.
[0041] In block 78, the server communicates its inability to accept
and perform the requested instructions by notifying the server
manager of an error. Flow then continues to block 80. In block 80,
the server manager upon receiving the error message restores the
previous settings of parameters in the database tables. By
restoring the previous settings of parameters in the tables, the
server manager database remains synchronized with the server
configuration. Flow then continues to block 82. In block 82, an
error is reported to the user notifying the user that the requested
modification was not performed. Flow then continues to block 84
where flow ends.
[0042] Returning to block 76, if the server accepts the instruction
and can perform the reconfiguration, flow continues to block 88. In
block 88, the server modifies the server configuration in
accordance with the updated configuration settings. Flow then
continues to block 90. In block 90, the server confirms to the user
that the requested modification has been performed. Because the
server has been successfully reconfigured, the server manager
database is synchronized with the server configuration. It is
possible, if the server being reconfigured is down, for example,
that no error message or confirmation message is received by the
server manager. In this case, the database modification will be
reversed, and an error reported, as described above when an
explicit error message is received. Flow then continues to block 84
where the process ends.
[0043] FIG. 7 is a block diagram illustrating software modules that
reside on the server manager 32 and the servers 22, 24, 26 that the
server manager 32 communicates with. As described briefly above,
the server manager 32 comprises a database that may advantageously
be configured as a plurality of tables containing information about
the configuration of the network servers. Although the server
configuration information in this specific embodiment is in the
form of a plurality of tables, a wide variety of data formats could
be used.
[0044] As illustrated in FIG. 7, a server table 94 may be provided
that contains information about the servers the server manager 32
is designated to communicate configuration parameters to. One
embodiment of a server table is illustrated in FIG. 9. Another
table 96 includes information about the network resources such as
web-sites, email accounts, and the like that are present on the
servers. This table may include information about location and
properties of all network resources present on the servers. An
embodiment of this site table is illustrated in FIG. 10. A network
address table 98 contains information about each set of network
addresses assigned to respective servers. This table is discussed
in additional detail below.
[0045] Also advantageously provided are one or more application
program tables 100. These tables contain information about the
configuration of a selected application program that is running on
one or more of the servers 22, 24, 26. For example, a web server
table includes information on all web site resources such as server
location, capacity, and the like that operate under the control of
the web server application program. Similarly, a media server table
includes information (such as, for example, maximum allowable
number of simultaneously delivered streams) on all network
resources that include media delivery capability and that use the
media server application program to deliver media content to
browsers.
[0046] A request queue 110 may be provided that stores requests to
add to or modify the information present in the database tables. A
FIFO queue may advantageously be utilized, and if desired, the
request queue 110 can be configured to suspend modification
requests under certain circumstances. For example, requests from a
particular user may be suspended because of payment collection
issues, for example, or requests which appear to be user errors,
such as deleting an entire web site from the servers, can be
suspended pending further investigation.
[0047] A dispatch module 112 is used to download information to the
servers 22, 24, 26 when the tables have been modified or new
information is added. The dispatch module triggers a daemon 116
that is resident on each server 22, 24, 26. As described above, the
daemon is configured to receive the modified or new parameters from
the server manager 32, and to reconfigure the application programs
120 such as web server, media server, etc.
[0048] FIG. 8 illustrates one daemon 116 embodiment in additional
detail. In this embodiment, the daemon 116 includes an I/O module
122 for communicating with the server manager 32. Also present is a
trigger module 124 which receives a message from the server manager
32 that the server configuration needs to be updated in order to
maintain synchronization with the database. Upon receiving this
message, the trigger module 124 initiates the operation of an
update module 126 and an error detection module 128. The update
module receives the configuration data from the server manager 32,
and modifies the application programs 120 accordingly. If the
application programs accept the re-configuration, the error
detection module sends a message to the server manager that the
re-configuration has been successful. As described above, if no
such message is received by the server manager 32, the database 34
is returned to its original state.
[0049] Returning now to the data stored in the database 34, FIGS.
9-12 illustrate specific embodiments of several of the data tables
in the embodiment of FIG. 7 described above. It will be appreciated
that these embodiments are only specific examples, and that more or
fewer table fields could be provided depending on the information
required to properly configure the application programs being used
and the tracking information that the web hosting service provider
would find useful in facility and customer management.
[0050] In FIG. 9, one embodiment of a server table 94 is
illustrated. In this embodiment, only two fields are provided, an
ID field 132 and a description field 134. The ID field comprises a
unique name for the machine, and the description field may include
a wide variety of information such as operating system, serial
number, physical location of the machine, and the like. Of course,
the description field 134 could be separated into several fields
dedicated to specific server information.
[0051] In FIG. 10, one embodiment of a site table 96 is
illustrated. This table comprises a comprehensive list of all of
the network resources such as web sites that are on the servers
controlled by the server manager 32. This table may include a field
140 for a unique site identification number (generally assigned by
the web hosting service provider), a field 142 identifying the
physical machine/server the site is resident on, a field 144 for
storing the user password to access site information and
modification tools, and a field 146 for the domain name if
applicable.
[0052] FIGS. 11 and 12 illustrate application program tables. In
FIG. 11, one embodiment of a table for media servers is
illustrated. This table may include a field 150 for a site ID for
each site having media delivery capacity. The table may also
include a server ID field 152, identifying the server the site is
located on, the field 154 for the space allocated for the site, and
a field 156 for the maximum number of simultaneously deliverable
media streams. In FIG. 12, a web server table is illustrated. This
table advantageously also includes a field 160 for the site ID, a
field 162 for the host server, and a field 164 for allocated space.
The table may also include a field 166 for the site IP address.
Additional fields 168, 170 for RAM memory and CPU allocation to the
web site may be provided in this table.
[0053] During the table update process, the server manager 32 may
derive or create and then enter the derived information into
certain fields without a user specifying the field data. For
example, if a user modifies the space allocated to their web site
from 10 to 500 MB, the site may need to be moved to another
physical server. If this is needed, the server manager 32 may be
programmed to select a new server without further user input based
on loading or available space considerations. The server selection
is then entered into the appropriate table fields.
[0054] IP address designation is another example of a configuration
parameter that may be performed automatically by the server manager
32. For example, if a new network resource such as a web site is
being added by a new or existing customer, or if an existing site
is being moved to a new physical server, an IP address must be
assigned to the site being created or moved. An IP address is
selected by searching the network address table 98 (FIG. 7) for an
unused IP address assigned to the server that the network resource
is to be resident on.
[0055] One advantageous embodiment of this process is illustrated
in FIG. 13. As shown in this Figure, to facilitate the search for
unused IP addresses, at block 176 the normal four field IP address
such as the IP address 123.45.255.1, is stored in a single field
representation such as 123452551, therefore becoming simply a
stored integer. The network address table 98 thus comprises blocks
of integers associated with corresponding servers. At block 178,
the integers in each block in the table are arranged in ascending
or descending numerical order. Integers in the table corresponding
to currently used IP addresses are tagged.
[0056] When a new IP address needs to be allocated to a network
resource, the network address table is searched for an unused IP
address. This search is performed quickly using the single field
representation because the search algorithm simply starts at the
lowest IP address assigned to the relevant server and searches
numerically upward until an available address is found. In this
embodiment, therefore, the system determines at decision block 180
of FIG. 13 whether or not a first numerically represented IP
address is already assigned to a network resource. If it is not,
the process moves to block 182 and assigns this address to the new
resource. If the first address is assigned, the next numerical IP
address is checked at decision block 184. If this address is
assigned, the system continues checking the next numerical IP
address. Once an unused IP address is identified, the system moves
to block 182 and assigns the unused address. When the next address
is to be assigned, the system again starts at the first numerical
address at block 180, and again increments numerically until the
first available address is identified. This procedure results in
fast search times, and guarantees that IP addresses are used
efficiently without wasting unused addresses in the middle of the
block assigned to a given server that may have become available due
to the deletion of a previously supported web site or other network
resource.
[0057] Thus, utilizing the above described principles, the entire
process of modifying server configuration and maintaining
synchronization with a database that has the current server
configuration stored therein may be performed automatically and
without any intervention on the part of a network administrator at
the web hosting service provider facility. Control over server
configuration is maintained, an accurate centralized database of
information for use by the administrator for allocating resources,
user billing, and other management functions is provided, while at
the same time providing a reduction in labor and cost over
conventional server configuration management techniques.
[0058] The foregoing description details certain embodiments of the
invention. It will be appreciated, however, that no matter how
detailed the foregoing appears in text, the invention can be
practiced in many ways. As is also stated above, it should be noted
that the use of particular terminology when describing certain
features or aspects of the invention should not be taken to imply
that the terminology is being re-defined herein to be restricted to
including any specific characteristics of the features or aspects
of the invention with which that terminology is associated. The
scope of the invention should therefore be construed in accordance
with the appended claims and any equivalents thereof.
