A new Request for Comments is now available in online RFC libraries. RFC 5973 Title: NAT/Firewall NSIS Signaling Layer Protocol (NSLP) Author: M. Stiemerling, H. Tschofenig, C. Aoun, E. Davies Status: Experimental Stream: IETF Date: October 2010 Mailbox: Martin.Stiemerling@neclab.eu, Hannes.Tschofenig@nsn.com, cedaoun@yahoo.fr, elwynd@dial.pipex.com Pages: 90 Characters: 219962 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-nsis-nslp-natfw-25.txt URL: http://www.rfc-editor.org/rfc/rfc5973.txt 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. This document is a product of the Next Steps in Signaling Working Group of the IETF. EXPERIMENTAL: This memo defines an Experimental Protocol for the Internet community.
