Edge-to-edge Resource Provisioning and Admission Control in Diffserv Networks

This paper describes an edge-to-edge dynamic resource provisioning and admission control process over multiple domains through a Bandwidth Management Point (BMP). The main goals are to achieve signaling scalability and optimum resource utilization. The BMP of each domain makes a pipe type reservation to possible destination regions on behalf of its customers and modifies the pipe size based on the traffic rate. For the traffic rate estimation and admission control process, we use two different methods: parameter-based, and measurementbased. Both of them are based on a Gaussian distribution under an assumption of the Central Limit Theorem. The scalability and utilization problems are minimized by using a threshold based dynamic provisioning scheme.
