Diameter Group Signaling
RFC 9390

Received changes through RFC Editor sync (created alias RFC 9390, changed abstract to 'In large network deployments, a single Diameter node can support over a million concurrent Diameter sessions.  In some use cases, Diameter nodes need 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 can result in many thousands of command exchanges enforcing the same operation on each session in the group.  In order to reduce signaling, it is desirable to enable bulk operations on all (or part of) the sessions managed by a Diameter node using a single or a few command exchanges.  This document specifies the Diameter protocol extensions to achieve this signaling optimization.', changed pages to 21, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2023-04-25, changed IESG state to RFC Published)
