Abstract

The emergence of intelligent optical network (ION) not only introduces the function of intelligent connection control, but also makes some new-style optical layer services possible. There are many kinds of survivability schemes applied in ION with mesh topology. According to the recovery degree of traffic, differentiated resilience service (DRS) can provide an appropriate survivability scheme from them. In this paper, a differentiated resilience service scheme in intelligent optical network is proposed. We firstly discuss some relative problems of DRS, and then define some DRS degrees in terms of recovery time for traffics. At last, the DRS protection/restoration modules of control plane in ION are designed and analyzed. Thus a DRS implementation method in ION is formed.
