Design and Implementation of a Network-Centric Micro-Mobility Architecture

This paper presents the design and implementation of the mobility plane architecture (MPA). MPA is a network architecture that provides micro-mobility in a network-centric way, that is, the burden of supporting micro-mobility is placed on the network and not on the mobile nodes. The implementation employs RSVP-TE to establish IP/IP and MPLS point-to-multipoint tunnels in order to direct traffic to the mobile nodes. DHCP is used for tracking the mobile node locations and RSVP-TE opaque data carries the location information to install routes to them. Results obtained in a lab-sized network and some quantitative comparisons between MPA and other related work are presented as well.
