tion and authorization, requested service discovery/location, and service usage charging, which are related to service management, must also be addressed. It is obvious that the problems of resource allocation on EPON and service management are related and should be addressed in an integrated manner to provide efficient mul- timedia services. We apply the IMS service plane enabled network architecture and develop a resource allocation method that, by integrating service plane func- tionality with EPON network traffic flow control scheme, provide efficient ser- vice access and management, and bandwidth resource allocation for multimedia services over EPON networks. The implemented system architecture consists of a service plane that provides the required service and resource management functions, and the EPON network with a traffic controller that classifies traffic flows into different service priority queues, and an inter-module communication mechanism that facilitates the infor- mation exchange between the service plane core and the EPON controller. We developed an EPON network resource management module in the service plane for service request admission and EPON resource control. This module utilizes users profile information available from the HSS in the IMS core, such as sub- scription and service priority to optimize the EPON networks resource allocation Service Delivery Platforms for multimedia traffic, both unicast and multicast traffic, and communicates with other modules in the service plane, such as billing module, to apply different price plans. With this module, the EPON resource controller will get instant user ser- vice information and apply it in making resource allocation decision based on user's service agreement and service priority. The resource management module performs user's service request administration control and resource sharing under the circumstance of differentiated traffic priority and traffic congestion, and pro- vides guaranteed performance for prioritized services.
