Abstract

According to one embodiment, a first computing device receives a first information packet from a second computing device. The second computing device receives the first information packet from a global computer network through a first router device. The first computing device outputs a second information packet to the global computer network through a second router device, such that the second information packet bypasses the first router device.

Claims

1. An information processing system, comprising:

a first computing device comprising;

means for receiving from a second computing device and a first local-area network a first information packet, the second computing device being configured to receive the first information packet from a global computer network, a first router and a second local-area network that bypasses the first local-area network; and

means for outputting a second information packet to the global computer network, such that the second information packet bypasses the second computing device.

2. The system of claim 1 wherein the first computing device is configured to output the second information packet to the global computer network from the second local-area network.

3. The system of claim 1 wherein the first computing device further comprises means for receiving a third information packet from the global computer network and the second local-area network.

4. The system of claim 1 wherein the first computing device comprises a network interface card.

5. The system of claim 1 wherein the first information packet originates from a client, and wherein the second computing device is coupled to the first router device and the global computer network to the client.

6. The system of claim 5 wherein the second information packet includes the first information packet and a reference to a data structure of a connection with the client.

7. The system of claim 1 wherein the means for outputting is configured to output the second information packet to the global computer network from a second router.

8. The system of claim 1 wherein the means for outputting is configured to output the second information packet to the global computer network from the second local-area network and a second router.

9. The system of claim 1 wherein the means for outputting is configured to output the second information packet to the global computer network from the second local-area network and the first router.

10. The system of claim 1 wherein the second computing device comprises an intelligent network interface card.

11. The system of claim 1 wherein the means for outputting is configured to output the second information packet to the global computer network from a third local-area network.

12. The system of claim 1 wherein the means for outputting is configured to output the second information packet directly to the global computer network.

13. A computer-readable memory medium containing instructions that, when executed by a first computing device, cause the first computing device to process information by performing a method comprising:

receiving from a second computing device and from a first local-area network a first information packet, the second computing device receiving the first information packet from a global computer network, a first router and a second local-area network that bypasses the first local-area network; and

outputting a second information packet to the global computer network, such that the second information packet bypasses the second computing device.

14. The computer-readable memory medium of claim 13 wherein the method comprises:

outputting the second information packet to the global computer network from the second local-area network.

15. The computer-readable memory medium of claim 13 wherein the method further comprises:

the first computing device receiving a third information packet from the global computer network and the second local-area network.

16. The computer-readable memory medium of claim 13 wherein the first computing device comprises a network interface card.

17. The computer-readable memory medium of claim 13 wherein the first information packet originates from a client, and wherein the second computing device is coupled to the first router device and the global computer network to the client.

18. The computer-readable memory medium of claim 17 wherein the second information packet includes the first information packet and a reference to a data structure of a connection with the client.

19. The computer-readable memory medium of claim 13 wherein the first computing device outputs the second information packet to the global computer network from a second router.

20. The computer-readable memory medium of claim 13 wherein the first computing device outputs the second information packet to the global information network from the second local-area network and a second router.

21. The computer-readable memory medium of claim 13 wherein the first computing device outputs the second information packet to the global information network from the second local-area network and the first router.

22. The computer-readable memory medium of claim 13 wherein the second computing device comprises an intelligent network interface card.

23. The computer-readable memory medium of claim 13 wherein the first computing device outputs the second information packet to the global computer network from a third local-area network.

24. The computer-readable memory medium of claim 13 wherein the first computing device outputs the second information packet directly to the global computer network.
