Reliability Guaranteed Path Protection under Multiple Constraints

Not Accessible

Your library or personal account may give you access

Abstract

A scheme based on a modified multi-constrained k-shortest path algorithm and a cost function with high efficiency for backup path selecting is proposed to provide path protection under multi-constraints. Simulation results demonstrate its significant superiority in restoration path-finding capability for QoS routing.
