Abstract

   This document describes a signaling method and protocol for RSVP-
   based admission control over IEEE 802-style LANs.  The protocol is
   designed to work both with the current generation of IEEE 802 LANs as
   well as with the recent work completed by the IEEE 802.1 committee.

1. Introduction

   New extensions to the Internet architecture and service models have
   been defined for an integrated services Internet [RFC-1633, RFC-2205,
   RFC-2210] so that applications can request specific qualities or
   levels of service from an internetwork in addition to the current IP
   best-effort service.  These extensions include RSVP, a resource
   reservation setup protocol, and definition of new service classes to
   be supported by Integrated Services routers.  RSVP and service class
   definitions are largely independent of the underlying networking
   technologies and it is necessary to define the mapping of RSVP and
   Integrated Services specifications onto specific subnetwork
   technologies.  For example, a definition of service mappings and
