Bulk Binding Update Support for Proxy Mobile IPv6
Abstract
For extending the lifetime of a mobility session, the Proxy Mobile
IPv6 specification requires the mobile access gateway to send a Proxy
Binding Update message to the local mobility anchor on a per-session
basis. In the absence of signaling semantics for performing
operations with group-specific scope, this results in a significant
amount of signaling traffic on a periodic basis between a given
mobile access gateway and a local mobility anchor. This document
defines optimizations to the binding update and revocation operations
in Proxy Mobile IPv6 for performing operations with group-specific
scope with the use of a group identifier.
