MPLS VPN in cellular mobile IPv6 architectures

Due to the prevalence of Internet and mobile communications, people sending messages through Internet has concentrated on security and encryption regarding data transmission. The VPN (virtual private network) is the way to keep personal data secure by sending data through the public network. Following the rapid growth of the network and the decrease of IPv4 network addresses, the Internet Engineering Task Force (IETF) has initiated the promotion of next generation IP (IPv6) instead of the current IPv4. IPv6 supports the mobility and security of mobile communication environments. Since the VPN currently does not support cellular mobile IPv6, the goal of this paper is to construct a MPLS VPN framework in the cellular mobile IPv6 (CMIv6) environment, and use the IPSEC defined by the IETF to keep the security and integrity of data transmission for future mobile communication systems.
