Micromobility protocols aim to improve localized mobility by reducing the handover overhead. The Mobility Plane Architecture (MPA) was designed to support micromobility in standard IP or MPLS/GMPLS networks in a network-centric way, that is, the burden demanded by micromobility is placed on the network, not on the mobile nodes. The aim of this paper is to present the reactive and proactive handover procedures supported by MPA, its modeling and performance evaluation. Results show that the proactive handover loses much less packets than reactive handover, being more suited for multimedia traffic.

Micro-mobility protocols aim to improve localized mobility by reducing the handover overheads. In this paper we present the Mobility Plane Architecture (MPA). This architecture was designed to support micro-mobility in standard IP or MPLS/GMPLS networks in a network-centric way, that is, the burden demanded by micro-mobility is placed on the network, not on the mobile nodes. The main advantages of this architecture are its independence of IPv6 and the absence of new protocols for supporting L3 mobility.
