System and method for avoiding error correction redundancy over the last link

摘要

A system and a method for avoiding error correction redundancy over the last link are disclosed. By substituting the end-to-end connection oriented reliable transport protocol with a connection oriented non-reliable transport protocol over the last link, the inherent overhead and extra traffic brought by the recovery mechanism is reduced and side effects introduced by link layer recovery ARQ disappear. A new protocol called TDP is proposed which mimics TCP using a UDP compliant header and adding a connection service. Both the termination equipment protocol stack and the end user equipment protocol stack are simplified.
