This document defines a Quality of Service (QoS) NSIS Signaling Layer Protocol (NSLP), henceforth referred to as the "QoS NSLP". This protocol establishes and maintains state at nodes along the path of a data flow for the purpose of providing some forwarding resources for that flow. It is intended to satisfy the QoS-related requirements of RFC 3726 [RFC3726]. This QoS NSLP is part of a larger suite of signaling protocols, whose structure is outlined in the NSIS framework [RFC4080]. The abstract NTLP has been developed into a concrete protocol, GIST (General Internet Signaling Transport) [RFC5971]. The QoS NSLP relies on GIST to carry out many aspects of signaling message delivery.

  NSIS Signaling Layer Protocol (NSLP) for Quality-of-Service Signaling


   This specification describes the NSIS Signaling Layer Protocol (NSLP)    for signaling Quality of Service (QoS) reservations in the Internet.    It is in accordance with the framework and requirements developed in    NSIS.  Together with General Internet Signaling Transport (GIST), it    provides functionality similar to RSVP and extends it.  The QoS NSLP    is independent of the underlying QoS specification or architecture    and provides support for different reservation models.  It is    simplified by the elimination of support for multicast flows.  This    specification explains the overall protocol approach, describes the    design decisions made, and provides examples.  It specifies object,    message formats, and processing rules.
