Abstract

Techniques for reducing interference in a network from management and control traffic to functional applications are provided. In one aspect, a method for regulating information flow between monitoring agents and a management server in a network includes the steps of: inserting an interface in the network to access stream based communications in the network; exporting control and data ports to each of the monitoring agents; receiving requests from one or more of the monitoring agents to establish sessions; and limiting a number of the sessions to open. A system for limiting interference in a network is also provided.

Claims

1. A method for regulating information flow between monitoring agents and a management server in a network, the method comprising the steps of:

inserting an interface in the network to access stream based communications in the network;

exporting control and data ports to each of the monitoring agents;

receiving requests from one or more of the monitoring agents to establish sessions;

limiting a number of the sessions to open by limiting the connections on the data ports without restricting connections on the control ports, whereby a connection pool is provisioned containing less than a number of connections needed for all of the monitoring agents to communicate with the management server, and wherein the connection pool is shared among the monitoring agents; and

dynamically modifying a limit on the number of sessions to open based on changes in network traffic by reducing the limit after a given time threshold passes with none of the monitoring agents waiting to send management information to the management server.

2. The method of claim 1, wherein the interface inserted in the network is a socket layer.

3. The method of claim 1, wherein the interface is inserted in an application layer of the network.

4. The method of claim 1, wherein the steps of claim 1 are performed by the management server.

5. The method of claim 1, further comprising the step of:

obtaining information about resource consumption in the network.

6. The method of claim 1, wherein the requests are received on a control port of the management server.

7. The method of claim 1, wherein the requests comprise an amount of data the monitoring agents want to communicate to the management server.

8. The method of claim 1, wherein the step of limiting the number of the sessions to open, comprises the steps of:

establishing a pool of tokens representing a total number of the sessions to open;

upon receipt of the requests, determining whether free tokens are available in the pool of tokens; and

providing tokens to the monitoring agents and establishing a session on the data ports if free tokens are available, otherwise denying connection.

9. The method of claim 8, wherein free tokens are unavailable, the method further comprising the step of:

requesting the monitoring agents to check back after a certain period of time to see if free tokens have become available.

10. The method of claim 8, wherein free tokens are unavailable, the method further comprising the step of:

notifying the monitoring agents when free tokens become available.

11. A computer program product for regulating information flow between monitoring agents and a management server in a network, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

insert an interface in the network to access stream based communications in the network;

export control and data ports to each of the monitoring agents;

receive requests from one or more of the monitoring agents to establish sessions;

limit a number of the sessions to open by limiting the connections on the data ports without restricting connections on the control ports, whereby a connection pool is provisioned containing less than a number of connections needed for all of the monitoring agents to communicate with the management server, and wherein the connection pool is shared among the monitoring agents; and

dynamically modify a limit on the number of sessions to open based on changes in network traffic by reducing the limit after a given time threshold passes with none of the monitoring agents waiting to send management information to the management server.

12. The computer program product of claim 11, wherein the interface is inserted in an application layer of the network.

13. The computer program product of claim 11, wherein the requests are received on a control port of the management server.

14. The computer program product of claim 11, wherein the program instructions, when limiting the number of the sessions to open, further cause the computer to:

establish a pool of tokens representing a total number of the sessions to open;

upon receipt of the requests, determine whether free tokens are available in the pool of tokens; and

provide tokens to the monitoring agents and establishing a session on the data ports if free tokens are available, otherwise denying connection.

15. The computer program product of claim 14, wherein free tokens are unavailable, and wherein the program instructions further cause the computer to:

request the monitoring agents to check back after a certain period of time to see if free tokens have become available.

16. The computer program product of claim 14, wherein free tokens are unavailable, and wherein the program instructions further cause the computer to:

notify the monitoring agents when free tokens become available.

17. A system for limiting interference in a network, the system comprising a processor device coupled to a memory, the processor device being operable to:

insert an interface in the network to access stream based communications in the network;

export control and data ports to each of the monitoring agents; and

upon receipt of requests from one or more of the monitoring agents to establish sessions, use the interface to limit number of the sessions to open by limiting the connections on the data ports without restricting connections on the control ports, whereby a connection pool is provisioned containing less than a number of connections needed for all of the monitoring agents to communicate with the management server, wherein the connection pool is shared among the monitoring agents, and dynamically modify a limit on the number of sessions to open based on changes in network traffic by reducing the limit after a given time threshold passes with none of the monitoring agents waiting to send management information to the management server.

18. The system of claim 17, wherein the interface is a socket layer inserted in an application layer of the network.
