Abstract: A numerical simulation in term of the routing selection algorithm is proposed inthis paper. The result shows that the traffic has an obvious balancing trend; the block probability of connection requests has been reduced. At the same time,this algorithm has an excellent performance on bandwidth utility and sharing ofthe restoration resources.

Key words: optical network, distributed restoration, routing selection, generalized multi-protocol label switching
