METHOD AND APPARATUS FOR AVOIDING DUPLICATE NEGOTIATIONS DURING COMMUNICATION ESTABLISHMENT

摘要

A network element 204 acting as an intermediary between two peers 202, 206 monitors for control messages exchanged between the two peers when establishing a point to point protocol session. Relevant parameters within such control messages are stored 612 for later use. When retransmitted control messages are detected 610, the network element processes the retransmitted control message based on the stored parameters 618 such that additional negotiation loops are avoided. In this manner, the effects of non-simultaneous link establishment and differing timeout timers are mitigated by the network element.
