Enhanced WBEM-based Inter-AS SLA Management for QoS-guaranteed Multimedia Services

Many mission-critical applications such as video conferencing, video telephony cannot reliably run on today´s networks if only best-effort packet forwarding is used. In order to provide QoS-guaranteed DiffServ-over- MPLS service across multiple domain networks, each NMS should be able to collect all the related information and negotiate SLA with other service providers and customers. Policy-based networking can provide a good framework for dynamic network management. DMTF WBEM and CIM provide system and platform independent standards for distributed networking environments. In this paper, we propose a policy-based Inter-AS SLA management system with WBEM architecture and standard management information based on DMTF CIM to provide end-to-end QoS-guaranteed DiffServ-over-MPLS inter-AS traffic engineering. The detailed implementation of proposed system with performance analysis is explained.
