Bifurcated traffic and channel assignment (BITCA) to interconnected metro rings

Ashwin Anil Gumaste; Susumu Kinoshita; Koji Takeguchi; Gerardo Castañón

We have proposed a bifurcated approach to channel assignment in interconnected metro-rings and are able to reduce the net kind of transponder cards needed for dynamic traffic requests. We have compared different tunable cards and estimated a relation for economical optimized tunability for a given number of wavelengths and see that the optimized transponder need not have tunability greater than /spl lambda//sub max//10 for optimized throughput and blocking probability.
