Proxy Mobile IPv6 (PMIPv6) is standardized by IETF to supply mobility
management for mobile nodes (MN) in a local small area. When the
numbers of MNs which attaching to the same MAG is very large, it will
cause the problem that the arrival rate of data traffic is far
surpass the process capacity of the MAG. So the MAG will suffer from
process bottleneck. The IETF is working on optimization for PMIPv6.
This document proposes a load sharing solution for MAGs by migrating
the Picked Mobile Node (PMN) to some MAGs without overload to sharing
the traffic load, which can relieve stress of the overloaded MAG and
improve the performance of PMIPv6 network.
