Transparent support of protocol and data compression features for data communication
First Claim
1. Apparatus for linking a local endpoint application running at a source of digital data with an application running at a network endpoint application at a receiver of said digital data, said local and network endpoint applications capable of communication over a communication channel, comprising, in combination:
- a proxy engine placed at said source of digital data for conducting simultaneous communication sessions between said source and said destination over said communication channel,said proxy engine comprising at least one software routine for determining whether a security protocol, multiple channel protocol, data compression protocol, link control protocol or network control protocol is supported by the network endpoint application but not the local endpoint application;
said proxy engine further comprising at least one software routine for implementing for said local endpoint application at least one security protocol, multiple channel protocol, data compression protocol, link control protocol or network control protocol that is supported by the network endpoint application but not the local endpoint application protocol feature to thereby permit said local and network endpoint applications to communicate in accordance with said implemented protocol; and
communications hardware responsive to said proxy engine and interfacing with said communication channel for placing said digital data from said local endpoint application onto said communication channel for transmission to said receiver,whereby bilateral digital communication between said local and network endpoint applications is improved.

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.

9. In a system comprising a source of data, a receiver of data and a communication channel linking the source to the receiver, a method for setting up a data transmission session between a local endpoint application at said source and a network endpoint application at said receiver with a proxy engine in a transparent manner, comprising the steps of:
-
(1) determining the link control protocols that are supported by the network endpoint application; (2) determining the link control protocols that are supported by the local endpoint application; (3) enabling the link control protocols that are supported by both the network endpoint application and the combination of the proxy engine and the local endpoint application, and thereafter (4) transmitting data between the local endpoint application and the network endpoint application, whereby data is able to be transmitted from the source of the data to the receiver of the data over the communication channel.
