Abstract

The Next Steps in Signaling (NSIS) working group is considering protocols for signaling information about a data flow along its path in the network. The NSIS suite of protocols is envisioned to support various signaling applications that need to install and/or manipulate such state in the network. Based on existing work on signaling requirements, this document proposes an architectural framework for these signaling protocols.

Abstract

   The Next Steps in Signaling (NSIS) working group is considering
   protocols for signaling information about a data flow along its path
   in the network.  The NSIS suite of protocols is envisioned to support
   various signaling applications that need to install and/or manipulate
   such state in the network.  Based on existing work on signaling
   requirements, this document proposes an architectural framework for
   these signaling protocols.

   This document provides a model for the network entities that take
   part in such signaling, and for the relationship between signaling
   and the rest of network operation.  We decompose the overall
   signaling protocol suite into a generic (lower) layer, with separate
   upper layers for each specific signaling application.
