摘要：The management of VPC is to reduce the call blocking probability, increase responsiveness, stability, and fairness. The management functions in the evaluations use statistical multiplexing of VCCs and deterministic multiplexing for the VPCs, i.e. each VPC gets a certain portion of the capacity to be held over a long period of time compared to inter arrival times of new connections. (Statistical multiplexing can be used for VPCs, which can be allowed to exceed their assigned capacity, as long as they conform to some statistically defined parameters.) Fundamentally different approaches for VPC capacity reallocations are compared and their pros and cons are discussed. The capacity is managed in bundles or capacity units (c.u.), to decrease the computation effort for the central and distributed approaches.
