Abstract

Nested NATs or multi-layer NATs are already widely deployed. They are characterized by two or more NAT devices in the path of packets from the subscriber to the Internet. Moreover, NAT devices current deployed are PCP unaware and It is assumed that NAT aware PCP devices will take a long time to be rolled out. Therefore in order to lower the adoption barrier of PCP and make it work for current deployed networks, this document proposes a few mechanisms for PCP-enabled applications to work through NATs with varying levels of PCP protocol support.
