Summary :

A dynamic pre-allocated connection (DPC) scheme is proposed to support fast handoff and to effectively utilize wireline links in a multi-connection call environment. Handoff can be quickly executed in real-time with reduced connection overhead, since the proposed scheme uses pre-allocated switched virtual connections (PSVCs). This dynamic resource management scheme increases link utilization due to statistical multiplexing effects. A path-loop elimination algorithm can be applied to remove duplicate resource usages. The DPC scheme in an environment of multi-connection calls is analyzed to obtain three probabilities; 1) new multi-connection call blocking probability, 2) multi-connection handoff call blocking probability, and 3) fast handoff failure probability.
