Technical Summary

NSIS Quality of Service (QoS) signaling enables applications to perform
QoS reservation along a data flow path.  When the data flow path contains
IP tunnel segments, NSIS QoS signaling has no effect within those tunnel
segments and the resulting QoS-untended tunnel segments could become the
weakest QoS link which may invalidate the QoS efforts in the rest of the
end-to-end path. This document defines a solution to this problem by
mapping end-to-end QoS session requests to corresponding QoS sessions
in the tunnel, thus extending the end-to-end QoS signaling into the IP
tunnel segments.

Working Group Summary

The document is a product of the NSIS working group. The WG has reviewed
the document thoroughly, and it has been an important extension to the
protocol family.

Document Quality

The document is a supplemental document to the core NSIS protocols, and 
extends the core specifications to add support for IP tunnels. The
technical details have been validated as part of the work on NSIS
protocol operation on mobile environments.
