Technical Summary The draft 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 public 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. Working Group Summary There have been several WGLC on the document, plus several pre-WGLCs on the document. The editors have gotten extensive feedback from implementors and have clarified text based upon the feedback. Protocol Quality There are 3 or more independent implementations of the NSLP, and there were multiple interop events in the past. Personnel The document shepherd is Jukka Manner (firstname.lastname@example.org). Lars Eggert (email@example.com) reviewed the document for the IESG.
