IPv6 is introduced mainly to resolve the address space issues and also provides several advanced features. IPv6 is estimated to replace IPv4 in a very near future. Dual Stack Mobile IPv6 (DSMIPv6) is an extension of mobile IPv6 to support mobility of devices irrespective of IPv4 and IPv6 network. This paper provides an architectural overview of the existing DSMIPv6 implementation and software architecture to understand the significant modifications which have been made on DSMIPv6 basic implementation to achieve the requirements. The scope of the paper is to implement the Dual-Stack Mobile IPv6 (DSMIPv6) protocol as per the IETF (Internet Engineering Task Force) draft.
