RFC 5354 ASAP & ENRP Common Parameters September 2008
1. Introduction
The Aggregate Server Access Protocol (ASAP) [RFC5352], in conjunction
with the Endpoint Handlespace Redundancy Protocol (ENRP) [RFC5353],
provides a high-availability, data-transfer mechanism over IP
networks.
Both protocols work together and so share many common parameters used
in message formats. This document details the common message
parameters shared between the two protocols. This document provides
parameter formats only; for procedures and message composition,
please refer to the respective [RFC5352] and [RFC5353] documents.
