WBEM-Based SLA Management Across Multi-domain Networks for QoS-Guaranteed DiffServ-over-MPLS Provisioning

For QoS guaranteed DiffServ-over-MPLS connection provisioning in multi-domain networks, the managed objects in each domain should be globally standardized and publicly accessible by other NMSs. And each NMS participating in the inter-domain networking should negotiate with other NMSs for end-to-end service provisioning. In this paper, we propose SLA negotiation by COPS protocol and design the managed objects by expanding existing experimental DMTF CIM MOFs. We propose service location protocol based directory agent to register/discover the NMSs’ that participate in the multi-domain TE-LSP connection provisioning. For better performance, we design the multi-threaded provider implementations on OpenPegasus WBEM platform. The detailed implementations of the providers with performance analysis are explained.
