Title (EN) SYSTEM AND METHOD FOR AVOIDING ERROR CORRECTION REDUNDANCY OVER THE LAST LINK
(FR) SYSTEME ET PROCEDE PERMETTANT D'EVITER LA REDONDANCE DE LA CORRECTION D'ERREURS SUR LA DERNIERE LIAISON
Abstract:
(EN) 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.
(FR) La présente invention concerne un système et un procédé permettant d'éviter la redondance de la correction d'erreurs sur la dernière liaison. Substituer le protocole de transport fiable orienté connexion de bout en bout par un protocole de transport non fiable orienté connexion sur la dernière liaison, permet de réduire la surcharge système inhérente et le trafic supplémentaire engendrés par le mécanisme de restauration, et de faire disparaître les effets secondaires engendrés par ARQ de restauration sur la couche liaison. Un nouveau protocole appelé TDP est proposé, lequel imite le protocole TCP au moyen d'une en-tête souple UDP et d'un service de connexion ajouté. Le mode de réalisation susmentionné permet de simplifier à la fois l'empilement de protocoles d'équipement de terminaison et l'empilement de protocoles d'équipement d'utilisateur final.
