Interdomain routing through QoS-class planes

Abstract

This article presents an approach to delivering
\nqualitative end-to-end quality of service
\n(QoS) guarantees across the multiprovider Internet.
\nWe propose that bilateral agreements
\nbetween a number of autonomous systems (ASs)
\nresult in the establishment of QoS-class planes
\nthat potentially extend across the global Internet.
\nThe deployment of a QoS-enhanced Border
\nGateway Protocol (BGP) with different QoSbased
\nroute selection policies in each of the
\nplanes allows a range of interdomain QoS capabilities
\nto coexist on the same network infrastructure.
\nThe article presents simulation results
\nshowing the benefits of the approach and discusses
\naspects of the performance of QoSenhanced
\nBGP.
