A novel host mobility support method in IPv4/IPv6 network of RANGI architecture

With the growing demand of the host mobility, the problems of overloading of IP address semantics are becoming increasingly serious. People have figured out various ID/Locator split technologies to support host mobility. In fact, current network environment is still in mixed IPv4/IPv6 transition phase, but the existing technology for host mobility in this transition phase is not considered comprehensively. In this paper, we propose a novel method to support host mobility between IPv4 and IPv6 network, and give a detailed explanation through a new ID/Locator split architecture which called RANGI (Routing Architecture for the Next Generation Internet). There are two contributions in this method: First, it supports the host mobility in transition phase; second, it is like the host mobility means in IPv6, so it provides a good capacity of smooth transition from IPv4 to IPv6.
