Distributed Fault Management in WBEM-Based Inter-AS TE for QoS Guaranteed DiffServ-over-MPLS

Distributed fault management and event notification are essential in Inter-AS Traffic Engineering (TE). In this paper we design and implement distributed fault management for WBEM based inter-AS TE. We designed DMTF Managed Object Format (MOF) based Managed Object (MO) for fault management. Using the Event Model in standard Common Information Model (CIM) in DMTF WBEM we implemented fault indication and SNMP trap handling mechanisms in indication and SNMP providers accordingly on OpenPegasus [1]. We extended existing providers with new SNMP provider which is not supported by OpenPegasus WBEM, and SNMP manager functionalities. The detailed design and implementation of SNMP, indication, instance and other C++ based providers on OpenPegasus WBEM for inter-AS TE are explained.
