The traditional hierarchical structure of cellular networks has led
to deployment models which are heavily centralized. Mobility
management with centralized mobility anchoring in existing
hierarchical mobile networks is quite prone to suboptimal routing and
issues related to scalability. Centralized functions present a
single point of failure, and inevitably introduce longer delays and
higher signaling loads for network operations related to mobility
management. To make matters worse, there are numerous variants of
Mobile IP in addition to other protocols standardized outside the
IETF, making it much more difficult to create economical and
interoperable solutions. In this document we examine the problems of
centralized mobility management and identify requirements for
distributed and dynamic mobility management.
