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.

This document is a product of the Next Steps in Signaling Working
Group of the IETF.
