Abstract

BPEL Driven Policy Manager (BDPM) designed to coordinate network resources with Web service interfaces for IMS environments is developed. BPEL workflow is applied to the policy manager for achieving end-to-end assurances of QoS and bandwidth on heterogeneous network resources. BDPM analyzes QoS-related information from IMS, and identifies appropriate policy workflow to invoke end-to-end network services by allocating resources adaptively. The resource allocation results are enforced to the distributed network-resource-management systems using service oriented architecture (SOA) through Web service interface. Using prototype implementation of BDPM, various descriptions of QoS requirements from IMS core can be adaptively processed by BDPM and end-to-end network resource management is successfully conducted.
