Architecture and protocol for extensible and scalable communication
View Patent ↗A system performs information technology (IT) tasks using a computer. Examples of IT tasks include installing or configuring software, displaying alerts, executing programs or scripts on the endpoint, or logging activities. In an embodiment of the system, a connection initialization module receives a request for a persistent connection over a network from a managed endpoint. The request is accepted and a persistent connection is opened with the managed endpoint. A tier-1 module then receives configuration information from the managed endpoint over the persistent connection. The configuration information includes a list of functional plugins on the managed endpoint, where a functional plugin comprises a software module for performing an IT task. The tier-1 module stores this configuration information along with information describing the persistent connection and maintains the persistent connection in an open state.
1. A computer-implemented method for performing information technology (IT) tasks using a computer, the method comprising:
receiving a request for a persistent connection over a network from a managed endpoint;
opening the persistent connection with the managed endpoint based on the request;
receiving configuration information from the managed endpoint including a list of at least one functional plugin on the managed endpoint, the at least one functional plugin including a software module for performing an IT task;
storing information describing the persistent connection and the configuration information; and
maintaining the persistent connection in an open state.
2. The computer-implemented method of claim 1 , wherein the request from the managed endpoint traverses a firewall configured to block connection requests directed to the managed endpoint.
3. The computer-implemented method of claim 1 , further comprising:
receiving a notification from a source functional plugin on the computer, the notification indicating a command for execution on the managed endpoint; and
sending a command message to the managed endpoint using the persistent connection, the command message including the command for execution and an indication of a type of a destination functional plugin at the managed endpoint.
4. The computer-implemented method of claim 3 , further comprising receiving an acknowledgement message from the managed endpoint that the command message was delivered, the acknowledgement message received prior to the command completing execution on the managed endpoint.
5. The computer-implemented method of claim 4 , further comprising notifying the source functional plugin that the message was delivered in response to a sequence number in the acknowledgement message.
6. The computer-implemented method of claim 3 , further comprising:
placing the command message in a queue; and
removing the command message from the queue based on a relative priority of the source functional plugin.
7. The computer-implemented method of claim 1 , further comprising:
receiving version information from the managed endpoint, the version information indicating a version of the at least one functional plugin on the managed endpoint;
determining whether the version is a most recent version;
sending an upgrade message to the managed if the version is not the most recent version, the upgrade message including instructions for upgrading the functional plugin.
8. A computer system for performing information technology (IT) tasks the computer system comprising:
a processor; and
a non-transitory computer-readable storage medium communicatively coupled to the processor, the non-transitory computer-readable storage medium storing executable computer program modules comprising:
a connection initialization module operable to:
receive a request for a persistent connection over a network from a managed endpoint; and
open the persistent connection with the managed endpoint based on the request; and
a tier-1 module operable to:
receive configuration information from the managed endpoint including a list of at least one functional plugin on the managed endpoint, the at least one functional plugin comprising a software module for performing an IT task;
store information describing the persistent connection and the configuration information; and
maintain the persistent connection in an open state.
9. The computer system of claim 8 , wherein the request from the managed endpoint traverses a firewall configured to block connection requests directed to the managed endpoint.
10. The computer system of claim 8 , further comprising:
a tier-2 module operable to receive a notification from a source functional plugin on the computer, the notification indicating a command for execution on a managed endpoint; and
wherein the tier-1 module is further operable to send a command message to the managed endpoint using the persistent connection, the command message including the command for execution and an indication of a type of a destination functional plugin at the managed endpoint.
11. The computer system of claim 10 , further comprising an acknowledgement module operable to receive an acknowledgement message from the managed endpoint that the command message was delivered, the acknowledgement message received prior to the command completing execution on the managed endpoint.
12. The computer system of claim 11 , further comprising a sequencing module operable to notify the source functional plugin that the message was delivered in response to a sequence number in the acknowledgement message.
13. The computer system of claim 10 , further comprising a queuing module operable to place the command message in a queue and remove the command message from the queue based on a relative priority of the source functional plugin.
14. The computer system of claim 8 , further comprising a plugin management module operable to:
receive version information from the managed endpoint indicating a version of a functional plugin on the managed endpoint;
determine whether the version is a most recent version; and
send an upgrade message to the managed endpoint if the version is not the most recent version, the upgrade message including instructions for upgrading the functional plugin.
15. A computer program product including a non-transitory computer-readable storage medium having executable computer program instructions recorded thereon for performing information technology (IT) tasks using a computer, comprising:
a connection initialization module operable to:
receive a request for a persistent connection over a network from a managed endpoint; and
open the persistent connection with the managed endpoint based on the request; and
a tier-1 module operable to:
receive configuration information from the managed endpoint including a list of at least one functional plugin on the managed endpoint, the at least one functional plugin including a software module for performing an IT task;
store information describing the persistent connection and the configuration information; and
maintain the persistent connection in an open state.
16. The computer program product of claim 15 , wherein the request from the managed endpoint traverses a firewall configured to block connection requests directed to the managed endpoint.
17. The computer program product of claim 15 , further comprising:
a tier-2 module operable to receive a notification from a source functional plugin on the computer, the notification indicating a command for execution on a managed endpoint; and
wherein the tier-1 module is further operable to send a command message to the managed endpoint using the persistent connection, the command message comprising the command for execution and an indication of a type of a destination functional plugin at the managed endpoint.
18. The computer program product of claim 17 , further comprising:
an acknowledgement module operable to receive an acknowledgement message from the managed endpoint that the command message was delivered, the acknowledgement message received prior to the command completing execution on the managed endpoint; and
a sequencing module operable to notify the source functional plugin that the message was delivered in response to a sequence number in the acknowledgement message.
19. The computer program product of claim 17 , further comprising a queuing module operable to place the command message in a queue and remove the command message from the queue based on a relative priority of the source functional plugin.
