Abstract-This paper addresses the subject of multi-objective routing for an NGN environment. We propose a framework for a flexible multi-metric path selection which is designed as additional functional part for an NGN core. The framework allows the integration of user devices in NGN and a flexible definition and integration of a wide range of routing criteria. For the flexible definition of routing criteria, we propose a universal criteria raster. The proposed framework provides the users with the possibility of defining path selection rules between his devices and NGN core based on various sets of freely defined and parameterized criteria. IndexTerms-Next generation networks, flexible multi-metric routing, multi objective decision analysis, multi-constrained optimal path problem.

“…As suggested in RFC 3272 [1] our LSP level monitoring performs end-to-end monitoring of individual LSP statistics. In addition to the actual bandwidth utilization, we also maintain PHY status, loss, signal quality, delay and activity statistics which can indicate wireless link stability with a varying significance depending on the QoS requirements of the payload.…”

Abstract. The visibility and success of Wireless Mesh Network (WMN) deployments has raised interest among commercial operators in this technology. Compared to traditional operator access networks WMNs have the potential to offer easier deployment and flexible self-reconfiguration at lower costs. A WMN-type architecture considered as an alternative for an operator access network must meet similar requirements such as high availability and guaranteed QoS in order to support triple-play content provisioning. In this paper we introduce an architecture of such a Carrier-grade Wireless Mesh Access Network (CG-WMAN). We then present our contribution, an approach to seamlessly integrate unidirectional broadcast cells (i.e. DVB-T) into such a CG-WMAN. This allows higher layer protocols to utilize broadcast cells like regular mesh links, where beneficial for a given payload and receiver distribution. We then present a typical use case and discuss for which combinations of traffic type, user distribution and QoS requirements the use of longer range broadcast technologies can help to improve the overall CG-WMAN performance in terms of throughput and reliability.

MPLS (Multiprotocol Label Switching) enables the utilisation of explicit routes and other advanced routing mechanisms in multiservice packet networks, capable of dealing with multiple and heterogeneous QoS (Quality of Service) parameters. Firstly the paper presents a discussion of conceptual and methodological issues raised by multiobjective routing optimisation models for MPLS networks. The major contribution is the proposal of a multiobjective routing optimisation framework for MPLS networks. The major features of this modelling framework are: the formulation of a three-level hierarchical routing optimisation problem including network and service performance objectives, the inclusion of fairness objectives in the different levels of optimisation and a two-level stochastic representation of the traffic in the network (traffic flow and packet stream levels). A variant of the general model for two classes Work partially supported by programme POSI of the III EC programme cosponsored by FEDER and national funds. of traffic flows, QoS traffic and Best Effort traffic, is also presented. Finally a stochastic teletraffic modelling approach, underlying the optimisation model, is fully described.
