NAT/Firewall NSIS Signaling Layer Protocol
RFC 5973, “NAT/Firewall NSIS Signaling Layer Protocol”, is an Experimental document published in October 2010 by M. Stiemerling, H. Tschofenig, C. Aoun, E. Davies. The canonical text is published by the RFC Editor.
Abstract
This memo defines the NSIS Signaling Layer Protocol (NSLP) for Network Address Translators (NATs) and firewalls. This NSLP allows hosts to signal on the data path for NATs and firewalls to be configured according to the needs of the application data flows. For instance, it enables hosts behind NATs to obtain a publicly reachable address and hosts behind firewalls to receive data traffic. The overall architecture is given by the framework and requirements defined by the Next Steps in Signaling (NSIS) working group. The network scenarios, the protocol itself, and examples for path-coupled signaling are given in this memo. This document defines an Experimental Protocol for the Internet community.
What “Experimental” means
Describes a specification that is part of a research or development effort, published so the community can gain experience with it.
