Capacity Placement Design Algorithm Based on Shared-path Protection
Xingming Li · Radio Engineering of China · 2007
the total transmission capacity required by a transport network to satisfy demand and protect it from failures contributes significantly to its cost.This paper presents a design algorithm MSC-JOCP,which is based on shared-path protection,to address the Jointly Optimized Capacity Placement problem in broadband mesh networks.The key idea of the algorithm is to dynamically modulate the metrics of the network's spans,so as to choose working and protecting routes given attention to load balance as well as maximally share the spare capacity.Simulation results show that the developed scheme effectively reduces the required total capacity and enhances the network resource utility.
