Abstract

A solution for reducing transmission pathway lengths within a distributed network, as embodied in various systems, methods, and non-transitory computer-readable storage media, may include migrating a TCP socket from a request server to a data server. The solution may further include reprogramming one or more routers to recognize a new packet route based on the migrated socket. The solution may include the one or more routers subsequently communicating directly with the data server while bypassing the request server.

Claims

1. A method for reducing transmission pathway lengths within a computer network, the method comprising:

receiving a resource request for accessing a resource, the resource access request sent to a request server from a client device via the computer network;

identifying a data server capable of servicing the resource access request;

sending a migrate socket request from the request server to the identified data server, wherein the data server establishes a socket based on socket state information in the migrate socket request; and

updating routing tables stored at one or more routers, wherein the update includes a new route associated with the established socket, the new route reducing a number of hops between the data server and the client device in comparison to at least one other route stored in the routing tables, and wherein the resource access request is serviced by the established socket that sends information related to the resource access request via the new route.

2. The method of claim 1, wherein the migrate socket request also includes information that identifies a requested resource that the client device is attempting to access.

3. The method of claim 1, further comprising sending information regarding the new route to one or more other servers, wherein routing tables at the one or more other servers are reprogrammed to include the new route based on the information regarding the new route.

4. The method of claim 3, wherein the routing tables stored at the one or more routers are updated based on a matched address and port information associated with a connection associated with the established socket.

5. The method of claim 1, wherein a transfer control protocol (TCP) connection is established between the client device and the data server.

6. The method of claim 5, further comprising establishing the TCP connection between the client device and the data server based on an exchange of a synchronize (SYN) packet from the client device and a synchronize acknowledge (SYNACK) packet from the data server, wherein the SYN packet is initially received by the request server that forwards the SYN packet to the data server and sends the SYNACK packet to the client device.

7. The method of claim 6, wherein a router receives the SYN packet sent from the client device, forwards the SYN packet to the request server, receives the SYNACK packet, and sends the SYNACK packet to the client device.

8. A non-transitory computer-readable storage medium having embodied thereon a program executable by a processor for implementing a method for reducing transmission pathway lengths within a computer network, the method comprising:

receiving a resource request for accessing a resource, the resource access request sent to a request server from a client device via the computer network;

identifying a data server capable of servicing the resource access request;

sending a migrate socket request from the request server to the identified data server, wherein the data server establishes a socket based on socket state information in the migrate socket request; and

updating routing tables stored at one or more routers, wherein the update includes a new route associated with the established socket, the new route reducing a number of hops between the data server and the client device in comparison to at least one other route stored in the routing tables, and wherein the resource access request is serviced by the established socket that sends information related to the resource access request via the new route.

9. The non-transitory computer-readable storage medium of claim 8, wherein the migrate socket request also includes information that identifies a requested resource that the client device is attempting to access.

10. The non-transitory computer-readable storage medium of claim 8, further comprising executable instructions for sending information regarding the new route to one or more other servers, wherein routing tables at the one or more other servers are reprogrammed to include the new route based on the information regarding the new route.

11. The non-transitory computer-readable storage medium of claim 8, wherein the routing tables stored at the one or more routers are updated based on a matched address and port information associated with a connection associated with the established socket.

12. The non-transitory computer-readable storage medium of claim 8, wherein a transfer control protocol (TCP) connection is established between the client device and the data server.

13. The non-transitory computer-readable storage medium of claim 12, further comprising executable instructions for establishing the TCP connection between the client device and the data server based on an exchange of a synchronize (SYN) packet from the client device and a synchronize acknowledge (SYNACK) packet from the data server, wherein the SYN packet is initially received by the request server that forwards the SYN packet to the data server and sends the SYNACK packet to the client device.

14. The non-transitory computer-readable storage medium of claim 13, wherein a router receives the SYN packet sent from the client device, forwards the SYN packet to the request server, receives the SYNACK packet, and sends the SYNACK packet to the client device.

15. A system for reducing transmission pathway lengths within a computer network, the system comprising:

a plurality of routers;

a plurality of data servers; and

a request server that;

receives a resource request for accessing a resource, the resource access request sent to a request server from a client device via the computer network;

identifies a data server of the plurality of data servers capable of servicing the resource access request;

sends a migrate socket request from the request server to the identified data server, wherein the data server establishes a socket based on socket state information in the migrate socket request, and

updates routing tables stored at one or more routers, wherein the update includes a new route associated with the established socket, the new route reducing a number of hops between the data server and the client device in comparison to at least one other route stored in the routing tables, and wherein the resource access request is serviced by the established socket that sends information related to the resource access request via the new route.

16. The system of claim 15, wherein the migrate socket request also includes information that identifies a requested resource that the client device is attempting to access.

17. The system of claim 15, wherein the request server further sends information regarding the new route to one or more other servers, wherein routing tables at the one or more other servers are reprogrammed to include the new route based on the information regarding the new route.

18. The system of claim 15, wherein the routing tables stored at the one or more routers are updated based on a matched address and port information associated with a connection associated with the established socket.

19. The system of claim 15, wherein a transfer control protocol (TCP) connection is established between the client device and the data server.

20. The system of claim 19, wherein the established TCP connection between the client device and the data server is based on an exchange of a synchronize (SYN) packet from the client device and a synchronize acknowledge (SYNACK) packet from the data server, wherein the SYN packet is initially received by the request server that forwards the SYN packet to the data server and sends the SYNACK packet to the client device.
