ABSTRACT

Multiprotocol label switching (MPLS) provides a framework for doing more flexible traffic engineering via its explicit routing capability. In this paper, MPLS routing models with two different objectives that utilise MPLS explicit routing are presented and discussed. The objectives are to minimise the network cost and maximise the minimum residual link capacity. The model that maximises the minimum residual link capacity is found to perform substantially better, in terms of network throughput and packet loss. The performance is verified by using the well-known ns-2 simulator under different network loads. The MPLS techniques described in this paper can substantially improve network throughput and user perception of quality in comparison to traditional intra-domain routing methods.

    • "Although RSVP with Traffic Engineering (TE), (performance optimization of operational RSVP networks), is expected to be an important application in this problematic [7] an extended RSVP-TE protocol can be used in a much wider context for performance improvement. In this way, MPLS-TE is providing fast networks but with no local flow control, so assuming that devices are not going to fail or there will be no data loss. "

    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.
