End-to-End Link-Disjoint Path Computation and Resource Pre-Locking Scheme for Multi-Domain Packet Transport Networks

摘要

We propose a link-disjoint path computation and resource pre-locking scheme for hierarchical controlled multi-domain PTN, in order to decrease the path setup delay and improve resource utilization, as well as eliminate concurrent reservation conflicts. Simulations show its better performance in terms of disjoint path setup delay and blocking rate.
