| Abstract: | Network Survivability is an important issue in ATM network.In this paper,after analyzing the procedure of fast restoration,the restoration schedule problem is highlighted.The restoration schedule strategy with priority,P -RS,is presented to solve the problem,with different requirements of restoration time of various services in consideration.The results of simulation show that P -RS could improve the Valid Restoration Ratio to enhance the network survivability. |
