Survivability Protection in TWDM Optical Access Network with Dynamic Wavelength Scheduling
It is a key technical problem to locate failure correctly and perform protection switching for strong survivability in time and wavelength division multiplexing（TWDM）optical access network with dynamic wavelength scheduling. To solve the above problem, a cost-effective survivability protection schem...

| description | It is a key technical problem to locate failure correctly and perform protection switching for strong survivability in time and wavelength division multiplexing（TWDM）optical access network with dynamic wavelength scheduling. To solve the above problem, a cost-effective survivability protection scheme using control channel for fault location and based on dynamic wavelength scheduling was presented. For the scheme, the quantitative comprehensive analysis of survivability and cost was carried on. Analysis and calculations show that at the best the proposed scheme can pay only 1% of the cost for survivability protection and bring in 54% improvement in survivability. The proposed scheme can finish protection switching within 50 ms. |
