Abstract
A method and apparatus for distributing protocol processing among a plurality of computing platforms. Data communications equipment such as Remote Access Devices, Communication Servers, Terminal Servers, and Dial-up Routers provide single user or large-scale multiple user communication access to various computing environments. The equipment costs and performance of such access equipment is related to the amount of CPU processing capability and memory required to support the desired number of serial communication links. It is common to use protocols that terminate in their entirely in the same processing machine. This invention encompasses methods developed to increase the cost/performance capabilities of the communication equipment that supports these serial links, primarily by means of distributing the protocol processing for higher level protocols across multiple computing platforms, including devices such as modems. Examples of such higher level protocols include PPP, SLIP and RTP.
