ABSTRACT:
A method for efficiently setting up a data transmission session over a communication channel between a local endpoint application and a network endpoint application with a proxy engine in a manner that is transparent to the user. The proxy engine is placed in simultaneous communication sessions with the local endpoint application and the network endpoint application. The proxy engine determines the network control protocols that are supported by both the network endpoint application and the local endpoint application. The proxy engine enables the network control protocols that are supported by both the network endpoint application and the local endpoint application. Optionally, the proxy engine enables data compression techniques that are supported by both the network endpoint application and the proxy engine. After the network control protocols and data compression techniques (if desired) are enabled, the proxy engine transmits data between the local endpoint application and the network endpoint application over the communication channel.
