Title : NSIS Flow ID and packet classification issues

In current NSIS signaling, there are two main functions depending on
Flow ID, i.e. signaling message routing, data packet classification.
Specifically, the same information carried by the MRI is also used to
derive the packet classification at NSLP layer. This arrangement
assumes that identical information is required by the two functions
at two different layers, and thus has limitations. With the
introduction of NSIS applications in more complicated scenarios, such
assumption can no longer hold. Therefore, keeping the dependency
between the two functions hinders the development of NSIS. Efforts
have been made in different NSLP layer applications to extend the
relationship, e.g. QoS NSLP. This draft studied the possibility of
disjoining the information for the two functions. Problems faced by
the current system and different remedy options are discussed. With
these details, it is intended to help the reader to evaluate the
feasibility of redefining the packet classification information
signaling in NSIS.

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
