The QoS NSLP protocol is used to signal QoS reservations and is
independent of a specific QoS model (QOSM) such as IntServ or
DiffServ.  Rather, all information specific to a QOSM is encapsulated
in a separate object, the QSPEC.  This document defines a template
for the QSPEC including a number of QSPEC parameters.  The QSPEC
parameters provide a common language to be re-used in several QOSMs
and thereby aim to ensure the extensibility and interoperability of
QoS NSLP.  While the base protocol is QOSM-agnostic, the parameters
that can be carried in the QSPEC object are possibly closely coupled
to specific models.  The node initiating the NSIS signaling adds an
initiator QSPEC, which indicates the QSPEC parameters that must be
interpreted by the downstream nodes less the reservation fails,
thereby ensuring the intention of the NSIS initiator is preserved
along the signaling path.
