Abstract

In the Internet, the traffic crosses between two to eight autonomous systems before reaching its destination. Consequently, end-to-end quality of service requires provisioning across more than one domain. This paper proposes a new scheme for introducing MPLS technology into an inter-domain environment. Results obtained using the OPNET simulation platform show that extending MPLS across AS boundaries can improve the QoS perceived by the end users. This means that inter-domain traffic engineering is a promising solution for a QoS aware Internet. Document type: Part of book or chapter of book

Abstract

This paper proposes a novel and incremental approach to Inter-Domain QoS Routing. Our approach is to provide a completely distributed Overlay Architecture and a routing layer for dynamic QoS provisioning, and to use QoS extensions and Traffic Engineering capabilities of the underlying BGP layer for static QoS provisioning. Our focus is mainly on influencing how traffic is exchanged among non-directly connected multi-homed Autonomous Systems based on specific QoS parameters. We provide evidence supporting the feasibility of our approach by means of simulation. Document type: Part of book or chapter of book
