Abstract

In this research, we proposed two types of fault recovery schemes designed by combining the protection and the restoration methods in order to increase the survivability of GMPLS networks. The first method is a transformation of the 1+1 protection method where it consumes more resources than the 1+1 protection method but has a faster fault recovery speed. The second method is a combination of the 1+1 protection method and the restoration method and can enhance the performance after recoveries. Although the two methods proposed in this paper consume more resources than the ones before, they have outstanding recovery time and performance after recoveries.
