In large network deployments, a single Diameter peer can support over
a million concurrent Diameter sessions. Recent use cases have
revealed the need for Diameter peers to apply the same operation to a
large group of Diameter sessions concurrently. The Diameter base
protocol commands operate on a single session so these use cases
could result in many thousands of command exchanges to enforce the
same operation on each session in the group. In order to reduce
signaling, it would be desirable to enable bulk operations on all (or
part of) the sessions managed by a Diameter peer using a single or a
few command exchanges. This document specifies the Diameter protocol
extensions to achieve this signaling optimization.
