An aggregation network is provided that includes a plurality of interconnected access routers (150). This network is configured in accordance with a partially meshed (111) physical network topology. An individual subscriber makes a request for provision of a certain bursty traffic service. Responsive thereto, a resource handler functionality (140) determines which one of a plurality of logical network topologies (ring (160), duplicated tree (162) or partially meshed (164)) is best suited to support the provision of communications for that requested bursty traffic service. Factors that are evaluated in making this determination include quality of service (QoS) entitlement, communication network resource availability, and cost constraints. The plurality of interconnected access routers are then configured by the resource handler functionality to implement the determined logical network topology on the certain physical network topology and admit the flow of bursty traffic related to the subscriber request for handling by the logical network topology. |
