Title : NSIS Flow ID and packet classification issues
Author(s) : H. Cheng, et al.
Filename : draft-cheng-nsis-flowid-issues-01.txt
Pages : 23

In current NSIS signaling, Flow ID is used for multiple purposes,
e.g., providing routing information for signaling traffic,
identifying signaling state on NSIS nodes, and supplying packet
classification information regarding the data flow being signaled.
Due to the incompatibility of these functions, adverse effects are
introduced into NSIS operation, especially when addressing
information is complicated. In this draft, three scenarios where the
Flow ID cannot function properly are discussed, namely the Multiple
address case, Make-before-break case, and Address variation case. In
view of this, a solution employing a separate NSLP payload object,
i.e., Filter List, is proposed. The solution solves the Flow ID
usage problem in the three cases, and its operation details and
impacts on different aspects of NSIS system are reviewed in the
draft.

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
