Title : Next Steps in Signaling: Framework
Author(s) : R. Hancock et al.
Filename : draft-ietf-nsis-fw-04.txt

The Next Steps in Signaling working group is considering protocols
for signaling information about a data flow along its path in the
network. Based on existing work on signaling requirements, this
document proposes an architectural framework for such signaling
This document provides a model for the network entities that take
part in such signaling, and the relationship between signaling and
the rest of network operation. We decompose the overall signaling
protocol suite into a generic (lower) layer, with a separate upper
layers for each specific signaling application. An initial proposal
for the split between these layers is given, describing the overall
functionality of the lower layer, and discussing the ways that upper
layer behavior can be adapted to specific signaling application
This framework also considers the general interactions between
signaling and other network layer functions, specifically routing and
mobility. The different routing and mobility events that impact
signaling operation are described, along with how their handling
should be divided between the generic and application-specific
layers. Finally, an example signaling application (for Quality of
Service) is described in more detail.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
