This paper studies the possibilities of protecting backbonenetworks from multiple simultaneous failures. Althoughmethods that prepare the networks to survive singlefailures were extensively studied in the literature, in orderto provide extra high availability for mission-critical applications,the possibility of more than one simultaneous failureshas to be considered, too. The general technique ofprotecting a traffic flow is to establish a backup path wherethe traffic is redirected when a failure occurs along its activepath. Using this technique the total capacity reservationis at least doubled compared to the non-protected case.To avoid this large amount of bandwidth reservation by thebackup paths, the shared backup path protection paradigmcan be used, which is a promising scheme favored by the InternetEngineering Task Force. In this paper the two backuppath based protection scheme is introduced, which providessurvivability against any two simultaneous failures. Further,a novel shared protection strategy is proposed that improvesthe failure tolerance of the traditional single backuppath based protection. The performance of the different protectiontypes is examined through simulations.
