摘要： 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.

摘要： 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 transport layer connection multiplexing technique for improving performance of communications and delivery of a remotely-accessed application. The acceleration program establishes a transport layer connection from the client to the server that can be used by multiple applications on the client, or that is otherwise shared among applications of the client. The acceleration program multiplexes requests from one or more applications via the same transport layer connection maintained by the acceleration program. As such, the acceleration program can utilize the idle time of one application in using the transport layer connection to service a request of a second application through the same transport layer connection.

摘要： A method for compressing a stream of application layer network traffic communicated over a transport layer connection of a virtual private network connection between a client and a server using an appliance. The appliance intercepts one or more transport layer packets of a stream of application network traffic communicated via a transport layer connection of a virtual private network connection between a client and a server. The appliance accumulates data from a payload of the intercepted transport layer packets, determines data accumulated for transmission should be compressed based on one or more compression trigger, and compresses the accumulated data into a self-contained compression block for transmission.

摘要： A method for allowing or denying, by an appliance, access to a resource by an application on a client via a virtual private network connection includes basing the decision to allow or deny access on identification of the application. The appliance intercepts a request from an application on a client on a first network to access via a virtual private network connection a resource on a second network. The appliance identifies the application and associates with the intercepted request an authorization policy based on the identity of the application. The appliance determines, using the authorization policy and the identity of the application, to either allow or deny access by the application to the resource.
