Distributed Mobility Management - Framework & Analysis
draft-liebsch-dmm-framework-analysis-03.txt
Abstract
Mobile operators consider the distribution of mobility anchors to
enable offloading some traffic from their core network. The
Distributed Mobility Management (DMM) Working Group is investigating
the impact of decentralized mobility management to existing protocol
solutions, while taking into account well defined requirements, which
are to be met by a future solution. This document discusses DMM
using a functional framework. Functional Entities to support DMM as
well as reference points between these Functional Entities are
introduced and described. The described functional framework allows
distribution and co-location of Functional Entities and build a DMM
architecture that matches the architecture of available protocols.
Such methodology eases the analysis of best current practices with
regard to functional and protocol gaps.
