Internet Engineering Task Force (IETF) J. Manner Request for Comments: 5978 Aalto University Category: Informational R. Bless ISSN: 2070-1721 KIT J. Loughney Nokia E. Davies, Ed. Folly Consulting October 2010 Using and Extending the NSIS Protocol Family Abstract This document gives an overview of the Next Steps in Signaling (NSIS) framework and protocol suite created by the NSIS Working Group during the period of 2001-2010. It also includes suggestions on how the industry can make use of the new protocols and how the community can exploit the extensibility of both the framework and existing protocols to address future signaling needs.
