Supporting the Mobile Internet Using GSE/8+8

The current IP architecture is not designed for end-to-end mobility because of the overloaded semantics of the IP address. The IP address is used to both identify and locate a host. This dual role of the IP address hinders mobility. The research community acknowledges that decoupling the IP namespace into distinct Locator and Identity namespaces will help in providing mobility. This paper describes an approach to supporting improved mobility within the Internet based on using the GSE/8+8 Locator Identity Split concept, in order to achieve end-host mobility and session continuity. This work forms part of the Cisco-funded “Mobile Internet ” project
