Magalhães. An Architecture for Mobility Support in a Next Generation Internet

The current internetworking architecture presents some limitations to naturally support mobility, security and multi-homing. Among the limitations, the IP semantic overload seems to be a primary issue to be considered. In this pa-per we present a next generation internetworking architec-ture to overcome the IP semantic overload by introducing an identity layer located between the network and trans-port layers. This new layer provides a stable cryptographic identifier for end-hosts and seamlessly allows the deploy-ment of new services, such as mobility, multi-homing and security. A prototype was implemented and evaluated con-sidering some mobility scenarios, including intra-domain, inter-domain and simultaneous node mobility.
