RSVP (Resource Reservation Protocol), a proposed IETF standard, allows Internet applications to request reservation of resources along the path of a data flow so that applications can obtain predictable quality of service on end-to-end basis. In an Integrated Services Internet, routers and end-systems will cooperate to provide different levels of QoS (quality of service) guarantees such as controlled load and guaranteed delay. To meet the goal of providing end-to-end QoS guarantees, all the hops along a data flow's path must support reservation of resources and build firewall protection among competing data flows.
We address the problem of mapping RSVP mechanisms and associated integrated services onto an underlying IEEE 802.3 local-area networks (LANs). In particular, we will describe an admission control procedure for managing bandwidth in a shared LAN environment and discuss ongoing efforts in the area of building additional support in Ethernet switches and hubs to provide support for Integrated Services.
