Web-Service Solution for Inter-domain QoS Negotiation

Development of multimedia services, e.g. video on demand or IPTV and their flow transport over the IP multi-domain networks with quality of services (QoS) guarantees require appropriate management and control of QoS at service and also at the network level. The management and control system must first support cooperation between several independent network domains at service provisioning level while preserving independency of each domain at resource control level. Secondly, the system should integrate various low level mechanisms like QoS routing, resource reservation, admission control. Service Level Agreements and Specifications are used to express inter-entities commitments. This paper presents a web-service approach for implementing the inter-domain SLS negotiation process between network providers (pSLS). The solution is part of an end to end QoS integrated management system through heterogeneous networks defined by the ENTHRONE IST European project.
