Abstract

Described herein are methods and systems for application aware fastpath processing over a data network. In some examples, application fastpath operates to facilitate application specific fastpath processing of data packets transferred between a client device and a server device over a network session of a data network.

First claim

What is claimed is:

1 . A servicing node comprising:
a fastpath module for processing data packets, the fastpath module stored in memory at the servicing node and executed by at least one processor, wherein the fastpath module:
receives an application service request data packet from a client device, over a network session between the client device and the servicing node;
obtains one or more network addresses from the data packet and matches the obtained one or more network addresses with a session table for the network session between the client device and the servicing node;
determines that the one or more network addresses match an ingress session of the session table;
stores the application service request data packet into an ingress message; and
transmits the data packet to a server using egress session information.

2 . The system of claim 1 , wherein the servicing node is a server load balancer.

3 . The system of claim 1 , wherein the servicing node is an application delivery controller.

4 . The system of claim 1 , wherein the ingress message is an application layer message.

5 . The system of claim 1 , wherein the fastpath module further:
processes the application service request data packet according to an application layer protocol used by the network application.

6 . The system of claim 5 , wherein the application layer protocol is one of: HTTP, SIP, FTP, secure HTTP, instant messaging protocol, file transfer protocol, streaming protocol, or real time streaming protocol.

7 . The system of claim 1 , wherein the fastpath module is a high performance TCP stack.

8 . The system of claim 1 , wherein the fastpath module further:
transmits the ingress message to a network application in the application service request via fastpath processing.

9 . The system of claim 1 , wherein the fastpath module further:
receives a response data packet from the server; determines that the data packet is associated to the egress session; processes the data packet according to egress session information; and sends the processed data packet to the client device using ingress session information.

10 . The system of claim 9 , wherein the egress session information and the ingress session information are stored in the session table.

11 . The system of claim 9 , wherein the egress session and the ingress session are TCP sessions.

12 . The system of claim 9 , wherein the egress session and the ingress session are HTTP sessions.

13 . The system of claim 9 , wherein the egress session and the ingress session are SIP sessions.

14 . A method for processing data packets via a fastpath module stored in memory at a servicing node and executed by at least one processor, the method comprising:
receiving an application service request data packet from a client device, over a network session between the client device and the servicing node; obtaining one or more network addresses from the data packet and matches the obtained one or more network addresses with a session table for the network session between the client device and the servicing node; determining that the one or more network addresses match an ingress session of the session table; storing the application service request data packet into an ingress message; and transmitting the data packet to a server using egress session information.

15 . The method of claim 14 , wherein the servicing node is an application delivery controller.

16 . The method of claim 14 , wherein the ingress message is an application layer message.

17 . The method of claim 14 , further comprising:
processing the application service request data packet according to an application layer protocol used by the network application.

18 . The method of claim 17 , wherein the application layer protocol is one of: HTTP, SIP, FTP, secure HTTP, instant messaging protocol, file transfer protocol, streaming protocol, or real time streaming protocol.

19 . The method of claim 14 , further comprising:
transmitting the ingress message to a network application in the application service request via fastpath processing.

20 . The method of claim 14 , further comprising:
receiving a response data packet from the server; determining that the data packet is associated to the egress session; processing the data packet according to egress session information; and sending the processed data packet to the client device using ingress session information.
