Abstract

Bandwidth Brokers (BB) are a necessity to manage the intra and inter-domain resources in the Internet. In this paper we propose a way to setup inter-domain Label Switched Path (LSP) with the help of a BB in a MultiProtocol Label Switching (MPLS) over Diffserv network. We use traffic engineering extended Simple Inter-domain Bandwidth Broker Signaling Protocol (SIBBS-TE) to distribute the labels inter-domain. We also use a BB to interact with MPLS to setup an intra-domain LSP and to provision intra-domain traffic. With the help of a BB, we show how end-to-end Quality of Service (QoS) can be achieved.
