Abstract

Independent Quality of Service (QoS) models need to be set up in IP and ATM integration and they are difficult to coordinate. This gap is bridged when MultiProtocol Label Switching (MPLS) is used for IP-ATM integration purposes. Guarantee of Service (GoS) allows MPLS to improve performance of privileged data flows in congested domains. We first discuss the GoS requirements for the utilization in conjunction with MPLS. Then we propose a minimum set of extensions to RSVP-TE that allow signaling of GoS information across the MPLS domain.
