Design Criteria Robust and Flexible Protocol Framework Mobility Management Control Plane Protocol and the associated functions must be placed at the intelligent network edges and allow to avoid the need to involve all nodes in the network (including the core nodes) in the network update process Support for mobile hosts and mobile routers Support for IPv4 and IPv6 Evolutionary Architecture and Implementation Approach Mobility Management scheme should be based as much as possible on the existing network architectures and protocol framework Only minimal changes to the operation of mobile nodes should be expected Efficient Network Responsiveness The impact on the mobile application due to the service disruption caused by the mobile node’s movements and the associated network update and delivery processes should be reasonably minimal Acceptable Network Scalability and Performance The new requirements for Mobility Management functions should not result in decreased network scalability and performance |
