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 d i s a p p e a r. A new protocol called TDP is proposed which mimics TCP using a UDP compliant header and adding a connection service. Both 15 the termination equipment protocol stack and the end user equipment protocol stack are simplified.
