1 Common Constraint Information Extension to GMPLS Route for WDM Switch Optical Network draft-kang-ccamp-wdm-switch-info-00.txt Zhihong Kang ZhenYu Wang Feng Gao

2 Summary Contains information model for path computation Focus on 3-layer constraint characteristics WDM link layer WDM optical channel layer (Wavelength) Reachability to tributary side

3 WDM Link Layer Constraint Case

4 WDM Optical Channel Layer Constraint

5 WDM Optical Channel Layer Constraint (Cont.)

6 Reachable Tributary Sides Constraint

7 WDM Link Extension Info

8 WDM Link Extension Info (Cont.)

9

10 Next Step Get feedback to improve the draft Continue to extend switch capability Info model Consider influence of tunable laser information on switch capability Build switch capability Info model based on port with tunable laser transmitter or fixed wavelength manufactured laser
