DESIGN AND IMPLEMENTATIONS OF PORT CONTROL SYSTEM IN DS-LITE
IPv6 is considered as the only means tosolving the problem of public IPv4 address shortage.For many reasons there would be a long transition time from IPv4 to IPv6.Many transition solutions were introduced,such as Dual-stack Lite (DS-Lite) 1 which allows continuity of IPv4 service and incremental IPv6 introduction s.With DS-Lite solution,a Network Address Translation (NAT) function at the border of IPv4 and IPv6 network is a necessity to address IPv4 exhaustion.Port Control Protocol (PCP) is a work from Internet Engineering Task Force (IETF),which aims at enabling an explicit dialog with a middlebox such as a NAT or a firewall to open up and/or forward TCP or UDP port,This paper discusses using Port Control Protocol (PCP) in the DS-Lite context.An implementation of PCP client,especially designed in a way to test functionality of PCP server,with a web user interface provided and validation of this implementation,are described in this paper.This work demonstrates deployment of PCP,in the light of showing easiness of introducing new protocols for IPv6 transition.
