WBEM-based Inter-AS Traffic Engineering for QoS-guaranteed DiffServ Provisioning

Abstract

In order to provide QoS-guaranteed differentiated service across multiple domain networks, inter-AS (autonomous system) traffic engineering is essential. The managed objects in inter-AS traffic engineering should be standardized in public domain, and be easily accessible by other network operators. In this paper, we propose a design and implementation of WBEM-based inter-AS traffic engineering for QoS-guaranteed DiffServ provisioning. We expanded the MOF (Managed Object Format) for inter-AS traffic engineering with inheritance from DMTF CIM MOF. The detailed implementation of WBEM-based inter-AS traffic engineering with Open Pegasus is explained, and the performances are analyzed.
