Abstract
Epoch numbers are maintained in a pair wise fashion at a plurality of communication endpoints to provide communication consistency and recovery from a range of failure conditions including total or partial node failure and subsequent recovery. Once an epoch state inconsistency is recognized, negotiation procedures provide an effective mechanism to reestablish valid communication links without the need to employ global variables which inherently possess greater transmission and overhead requirements needed to maintain communications. Renegotiation of recognizably valid epoch numbers occurs on a pair wise basis.
