Abstract

Certain aspects of a method and system for quality of service and congestion management for converged network interface devices are disclosed. Aspects of a method may include processing at least one of: input/output (I/O) requests and network packets in a converged network interface card (CNIC) based on a class associated with each of the I/O requests and network packets by storing on the CNIC, information that identifies the I/O requests and network packets, without storing on the I/O requests and network packets on the CNIC

Claims

1. A method for handling data in a communication network, the method comprising:

processing at least one of;

input/output (I/O) requests and network packets in a converged network interface card (CNIC) based on a class associated with said at least one of;

said I/O requests and said network packets by storing on said CNIC, information that identifies said at least one of;

said I/O requests and said network packets, without storing on said CNIC said at least one of;

said I/O requests and said network packets.

2. The method according to claim 1, further comprising determining said class for said at least one of:

said I/O requests and said network packets based on at least one of;

a header and content of each of said at least one of;

said I/O requests and said network packets.

3. The method according to claim 1, further comprising selecting a particular queue associated with said at least one of:

said I/O requests and said network packets to be transmitted to a remote host based on said class.

4. The method according to claim 1, further comprising disabling a particular queue associated with said at least one of:

said I/O requests and said network packets to be transmitted to a remote host based on said class.

5. The method according to claim 1, further comprising filtering said at least one of:

said I/O requests and said network packets based on said class.

6. The method according to claim 1, further comprising regulating a rate at which said at least one of:

said I/O requests and said network packets are handled at said CNIC based on at least one pre-configured quality of service policy.

7. The method according to claim 1, further comprising regulating a rate at which said at least one of:

said I/O requests and said network packets are handled at said CNIC based on said class of said at least one of;

said I/O requests and said network packets.

8. The method according to claim 1, further comprising bypassing receive processing for transfer of data corresponding to said at least one of:

said I/O requests and said network packets from a host memory to said CNIC.

9. The method according to claim 1, further comprising prioritizing an order of said at least one of:

said I/O requests and said network packets in said plurality of queues based on said class.

10. A machine-readable storage having stored thereon, a computer program having at least one code section for handling data in a communication network, the at least one code section being executable by a machine for causing the machine to perform steps comprising:

processing at least one of;

input/output (I/O) requests and network packets in a converged network interface card (CNIC) based on a class associated with said at least one of;

said I/O requests and said network packets by storing on said CNIC, information that identifies said at least one of;

said I/O requests and said network packets, without storing on said CNIC said at least one of;

said I/O requests and said network packets.

11. The machine-readable storage according to claim 10, further comprising code for determining said class for each of said at least one of:

said I/O requests and said network packets to be transmitted based on at least one of;

a header and content of each of said at least one of;

said I/O requests and said network packets.

12. The machine-readable storage according to claim 10, further comprising code for selecting a particular queue associated with said at least one of:

said I/O requests and said network packets to be transmitted to a remote host based on said class.

13. The machine-readable storage according to claim 10, further comprising code for disabling a particular queue associated with said at least one of:

said I/O requests and said network packets to be transmitted to a remote host based on said class.

14. The machine-readable storage according to claim 10, further comprising code for filtering said at least one of:

said I/O requests and said network packets based on said class.

15. The machine-readable storage according to claim 10, further comprising code for regulating a rate at which said at least one of:

said I/O requests and said network packets are handled at said CNIC based on at least one pre-configured quality of service policy.

16. The machine-readable storage according to claim 10, further comprising code for regulating a rate at which said at least one of:

said I/O requests and said network packets are handled at said CNIC based on said class of said at least one of;

said I/O requests and said network packets.

17. The machine-readable storage according to claim 10, further comprising code for bypassing receive processing for transfer of data corresponding to said at least one of:

said I/O requests and said network packets from a host memory to said CNIC.

18. The machine-readable storage according to claim 10, further comprising code for prioritizing an order of said at least one of:

said I/O requests and said network packets in said plurality of queues based on said class.

19. A system for handling data in a communication network, the system comprising:

a converged network interface card (CNIC) processor that enables processing of at least one of;

input/output (I/O) requests and network packets based on a class associated with said at least one of;

said I/O requests and said network packets by storing on said CNIC, information that identifies said at least one of;
