Abstract

The present invention is directed towards systems and methods for dynamically deploying and executing acceleration functionality on a client to improve the performance and delivery of remotely accessed applications. In one embodiment. The client-side acceleration functionality is provided by an acceleration program that performs a plurality of the following acceleration techniques in an integrated and efficient manner: 1) multi-protocol compression 2) transport control protocol pooling, 3) transport control protocol multiplexing 4) transport control protocol buffering, and 5) caching. The acceleration program establishes a transport layer connection between the client and server, and intercepts network packets at the transport layer. The acceleration program uses a kernel-level data structure to access the network packet intercepted at the transport layer, and performs subsequently one or more of the acceleration techniques on the intercepted network packet at one interface point or point of execution of the acceleration program.
