Port Control Protocol (PCP) Extension for Port-Set Allocation

“…We are not referring to per-flow state, required for maintaining a NAT table in the gateway, as this is one of the A+P approaches. Additional signaling is needed to notify CPEs of their respective IPv4 addresses and portsets: DHCP [40], PCP [41] and TR69 variants are example protocols that serve this purpose. The following mechanisms are representatives of this class ( Figure 7): I-D.cui-softwireb4-translated-ds-lite [42], I-D.zhou-softwire-b4-nat [43], I-D.draft-penno-softwire-sdnat [44].…”

“…Therefore, the PCP Proxy is implemented in the CPE. This PCP Proxy function in CPE provides security controls for PCP requests coming from the outside [31]. It acts as an UPnP server that receives requests from the hosts using its internal interface on UDP port 44323 [25].…”

The transition between the utilization of IPv4 and IPv6 leads ISPs to develop a new mechanism so as to continue services for customers. In one hand, ISPs are pushed in implementing IPv6 protocol as the new technology. In another hand, there are many users and services still provided by IPv4 protocol. The CPE as an equipment at customer's premises must be able to pass any kind of services at any kind of IP traffic on dual stack environment. In order to support communication between IPv4 terminals beyond the IPv4 depletion issue, the CGN DS Lite approach is implemented. This paper presents two features of dual stack CPE which allow IPv4 traffic and applications implementing port forwarding operation to communicate through IPv6 access network. The PCP capability is taken into account between the CPE and CGN with some UPnP-PCP proxy capabilities in the CPE. We demonstrate that PCP gives an opportunity for customers in the home network behind the CGN to manage their interactive applications.
