A GMPLS Survivability Scheme Based Differentiated Services

This paper proposes a GMPLS survivability scheme based differentiated services. This algorithm which is based on three normal GMPLS survivability scheme models (namely global protection, reverse backup and local repair) chooses evaluation function to decide in advance most suitable restoration model for working path of each kind of traffic, then only employs it to calculate the backup path of working path, in order to gain the aim of differentiated restoration for different service traffic.
