Abstract

A method for distributed network packet statistics collection includes instantiating first and second operations that implement different portions of a network packet statistics collection task on processing nodes implemented on different processors in a network packet statistics collection system. The method includes utilizing an auto-discovery mechanism for the second operation to subscribe to a set of capabilities and identify the first operation as a matching operation. The method further includes establishing a channel between the first and second operations. The method further includes executing the network packet statistics collection task, where the first and second operations perform the different portions of the network packet statistics collection task.

Claims

1. A method for distributed network packet statistics collection in a test environment, the method comprising:

instantiating first and second operations that implement different portions of a network packet statistics collection task on processing nodes implemented on different processors in a network packet statistics collection system;

utilizing an auto-discovery mechanism for the second operation to subscribe to a set of capabilities and identify the first operation as a matching operation, wherein utilizing the auto-discovery mechanism includes;

publishing a set of attributes from the first operation to a broker;

at the second operation, subscribing, by transmitting a message to the broker, to an operation having the set of attributes;

receiving, at the second operation and from the broker, notification of the matching operation, the notification including information for connecting to the first operation; and

establishing a channel between the first and second operations; and

executing the network packet statistics collection task, where the first and second operations perform the different portions of the network packet statistics collection task.

2. The method of claim 1 wherein instantiating the first and second operations includes instantiating the first and second operations on processors associated with at least one of network port, a client, and test system chassis.

3. The method of claim 1 wherein instantiating the first and second operations includes instantiating the first and second operations on at least one of:

a dedicated processor within a chassis of the network statistics collection system or a dedicated processor separate from the network packet statistics collection system.

4. The method of claim 1 wherein instantiating the first and second operations includes instantiating the first and second operations on different virtual machines associated with the network packet statistics collection system.

5. The method of claim 1 wherein publishing the set of attributes includes publishing a processing node name, a channel accept report, and an operation ID to the broker.

6. The method of claim 1 comprising, in response to failure of the channel, utilizing the auto-discovery mechanism to identify matching operations to perform the network packet statistics collection task.

7. The method of claim 1 wherein the network packet statistics collection task includes recording different statistics for simulated packets by packet group identifier.

8. The method of claim 1 wherein the network packet statistics collection task includes combining statistics from packets received on different ports of the network packet statistics collection system.

9. The method of claim 1 comprising generating an abstract syntax tree representation of the network packet statistics collection task and utilizing the abstract syntax tree representation to assign the different portions of the network packet statistics collection task to the processing nodes.

10. A system for distributed network packet statistics collection in a test environment, the system comprising:

a network packet statistics collection system including a chassis and a client, each including a processor;

first and second processing nodes for executing on one or more of the processors;

first and second operations that implement different portions of a network packet statistics collection task for executing on the first and second processing nodes;

wherein the first and second operations are configured to utilize an auto-discovery mechanism for the second operation to subscribe to a set of capabilities and identify the first operation as a matching operation, wherein the first operation is configured to publish a set of attributes to a broker and wherein the second operation is configured to utilize the auto-discovery mechanism by;

subscribing, by transmitting a message to the broker, to an operation having the set of attributes; and

receiving, at the second operation and from the broker, notification of the matching operation, the notification including information for connecting to the first operation; and

wherein the first and second operations are configured to connect to each other and execute the network packet statistics collection task, where the first and second operations perform the different portions of the network packet statistics collection task.

11. The system of claim 10 wherein the first operation executes on a processor of a first port processor card, the second operation executes on a processor of a second port processor card, and wherein the broker executes on a processor of a chassis processor card.

12. The system of claim 10 wherein one of the first and second operations and the broker is configured to execute on a dedicated processor within a chassis of the network equipment test system or a dedicated processor separate from the network packet statistics collection system.

13. The system of claim 10 wherein the first and second operations and the broker are configured to execute on different virtual machines associated with the network packet statistics collection system.

14. The system of claim 10 wherein the first operation is configured to publish a processing node name, a channel accept report, and an operation ID to the broker.

15. The system of claim 10 wherein the first and second operations are configured to repeat the publishing and the subscribing to identify matching operations to perform the network packet statistics collection task.

16. The system of claim 10 wherein the network packet statistics collection task includes recording different statistics for simulated packets by packet group identifier.

17. The system of claim 10 wherein the network packet statistics collection task includes combining statistics from packets received on different ports of the network packet statistics collection system.

18. The system of claim 10 wherein the client is configured to generate an abstract syntax tree representation of the network packet statistics collection task and use the abstract syntax tree representation to assign the different portions of the network packet statistics collection task to the processing nodes.

19. A non-transitory computer readable medium having stored thereon executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:

instantiating first and second operations that implement different portions of a network packet statistics collection task on processing nodes implemented on different processors in a network packet statistics collection system;

utilizing an auto-discovery mechanism for the second operation to subscribe to a set of capabilities and identify the first operation as a matching operation, wherein utilizing the auto-discovery mechanism includes;

publishing a set of attributes from the first operation to a broker;

at the second operation, subscribing, by transmitting a message to the broker, to an operation having the set of attributes;

receiving, at the second operation and from the broker, notification of the matching operation, the notification including information for connecting to the first operation; and

establishing a channel between the first and second operations; and

executing the network packet statistics collection task, where the first and second operations perform the different portions of the network packet statistics collection task.
