Abstract

Aspects of a method and system for indicate and post processing in a flow through data architecture are presented. Aspects of the system may include a network interface controller that enables storage with zero copy of at least a portion of a plurality of received messages based on policies that may be enforced by the network interface controller and based on ULP provided buffers. The network interface controller may enable generation of a signal to a host processor that processes some of the stored plurality of received messages based on the policies that may be enforced by the network interface controller.

Claims

1. A method for processing received data in a communication system, the method comprising:

storing at least a portion of a plurality of received messages based on policies that are enforced by a network interface controller; and

generating a signal to a host processor that processes some of said at least a portion of said stored plurality of received messages based on said policies.

2. The method according to claim 1, comprising configuring said policies in said network interface controller.

3. The method according to claim 2, comprising generating policy state information based on said configured polices.

4. The method according to claim 2, wherein said policies comprise at least one of:

a connection identifier, a process identifier, a quantity of allocated storage resources for at least a portion of said plurality of received messages, a quantity of available storage resources, and at least one request type.

5. The method according to claim 2, comprising inspecting each of said plurality of received messages based on said policies.

6. The method according to claim 1, comprising determining one of:

accepting and rejecting, each of said plurality of received messages based on policy state information.

7. The method according to claim 6, comprising modifying connection state information based on said one of:

said accepting and said rejecting, one of said plurality of received messages.

8. The method according to claim 6, comprising modifying said policy state information based on said accepting one of said plurality of received messages.

9. The method according to claim 6, comprising storing said accepted said each of said plurality of received messages, in memory located within host memory, based on said policy state information.

10. The method according to claim 1, comprising retrieving said some of said at least a portion of said stored plurality of received messages from memory located within said network interface controller and storing said retrieved said some of said at least a portion of said stored plurality of received messages in host memory.

11. The method according to claim 1, comprising determining a location at which to store said at least a portion of said plurality of received messages based on at least one buffer pointer and corresponding length

12. The method according to claim 1, comprising performing upper layer protocol processing within said network interface controller to enable said storing.

13. A system for processing received data in a communication system, the system comprising:

circuitry that enables storage of at least a portion of a plurality of received messages based on policies that are enforced by a network interface controller; and

said circuitry enables generation of a signal to a host processor that processes some of said at least a portion of said stored plurality of received messages based on said policies.

14. The system according to claim 13, wherein said circuitry enables configuration of said policies in said network interface controller.

15. The system according to claim 14, wherein circuitry enables generation of policy state information based on said configured polices.

16. The system according to claim 14, wherein said policies comprise at least one of:

a connection identifier, a process identifier, a quantity of allocated storage resources for at least a portion of said plurality of received messages, a quantity of available storage resources, and at least one request type.

17. The system according to claim 14, wherein said circuitry enables inspection of each of said plurality of received messages based on said policies.

18. The system according to claim 13, wherein said circuitry enables determination of one of:

accepting and rejecting, each of said plurality of received messages based on policy state information.

19. The system according to claim 18, wherein said circuitry enables modification of connection state information based on said one of:

said accepting and said rejecting, one of said plurality of received messages.

20. The system according to claim 18, wherein said circuitry enables modification of said policy state information based on said accepting one of said plurality of received messages.

21. The system according to claim 18, wherein said circuitry enables storage of said accepted said each of said plurality of received messages, in memory located within host memory, based on said policy state information.

22. The system according to claim 13, wherein said circuitry enables retrieval of some of said at least a portion of said stored plurality of received messages from memory located within said network interface controller and storage of said retrieved said some of said at least a portion of said stored plurality of received messages in host memory.

23. The system according to claim 13, wherein said circuitry enables determination of a location at which to store said at least a portion of said plurality of received messages based on at least one buffer pointer and corresponding length

24. The system according to claim 13, wherein said circuitry enables performing upper layer protocol processing within said network interface controller to enable said storage.
