A Multihoming Mechanism to Support Network Mobility in Next Generation Networks

Abstract

One of major tasks at IETF NEMO WG is for supporting the seamless connectivity of mobile networks based on IPv6. This seamless connectivity can be provided by multiple accesses to multiple service providers with multiple wireless network interfaces. Classifications for possible multihoming cases must be one of the most important issues in order to find the scheme for supporting mobility in various multihomed mobile networks. The classification of various multihoming cases is the current target for mobility support in mobile networks at IETF NEMO WG. The main issue of these schemes is to extract the multihoming factors with mutually independent and orthogonal properties to each other. In order to get the factors, this paper firstly divides the routing path into three segments, secondly extracts three multihoming factors, which should have independent and orthogonal properties because each of them are from different segment, and finally classifies multihoming cases of mobile networks based on these factors. In addition to this novel scheme of classification, this paper also proposes a new scheme to support network mobility in the most general multihoming environment. This validation of this scheme is attained by network simulator-2
