Method of route optimization with dual mobile node in IPV4-only network

A method of achieving route optimization (RO) when a dual capable mobile Internet protocol version 6 (MIPv6) mobile node is connected with an IPv4-only network allows RO of packets to traverse a shorter route than the default one through the home agent (HA) using bidirectional tunneling, and leads t...

Summary:A method of achieving route optimization (RO) when a dual capable mobile Internet protocol version 6 (MIPv6) mobile node is connected with an IPv4-only network allows RO of packets to traverse a shorter route than the default one through the home agent (HA) using bidirectional tunneling, and leads to better bandwidth utilization. The method of RO with a dual MIPV6 node in an IPV4-only network includes updating the HA with an lPv4 address of the MN and deregistering a binding update (BU) with a corresponding node (CN) via the HA; informing the CN about its IPv4 address and receiving the CN's IPv4 address in reply; checking reachability of the CN in its IPv4 address using an IPv6-in-IPv4 tunnel; and sending and receiving Ipv6 data packets to/from the CN using a v4 tunnel.
