The Quality-of-Service (QoS) NSIS signaling layer protocol (NSLP) 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 reused 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.  This document defines an Experimental 
Protocol for the Internet community.
