Distributed Mobility Management: Current Practices and Gap Analysis
Abstract
This document analyzes deployment practices of existing IP mobility
protocols in a distributed mobility management environment. It then
identifies existing limitations when compared to the requirements
defined for a distributed mobility management solution.
