Abstract
A system and method for improving TCP performance in a L2 tunneling environment by snooping TCP/IP packets from the tunnel interface, terminating TCP locally and proxying TCP data in separate TCP connections. In particular, the system and method detects an encapsulated outgoing packet utilizing a Layer 2 tunneling protocol, processes a Point to Point Protocol layer in the outgoing packet to establishing Layer 2 tunneling protocol for a connection. The system and method also removes the Point to Point Protocol layer from the outgoing packet and inspects the outgoing packet for TCP information in the packet. The system and method forwards the outgoing packet to a locally driven application protocol path if TCP information is present, wherein the outgoing packet is encapsulated in association with the application protocol path.
