Descrição

Next Generation Network (NGN) management represents an enormous challenge due to the large number of managed elements, the variety of roles the managed entities play in the network and the difficulty of orchestrating management actions. Several NGN standardization bodies point toward Policy Based Management as the best approach for NGN network management. This paper describes a management solution for a NGN IP Multimedia Subsystem (IMS) QoS management scenario based on WBEM technology. The proposal is for a WBEM-based policy server, a graphical policy editor application and instrumentation logic for the NGN QoS Management. The graphical policy editor reduces the learning curve imposed by the policy specification language, allowing the specification of policies through a rich and user-friendly visual interface, hiding the CIM syntax complexity but keeping CIM’s potential.
