A heuristic optimization framework is proposed for routing virtually-concatenated 100Gb/s Ethernet over optical transport networks with distributed differential delay compensation. Under short computing times, reduced buffer sizes and limited link capacity requirements are obtained.
We propose a simplified framework that exploits grooming and virtual concatenation to minimize the optical transport network cost for supporting 40 Gb/s and 100 Gb/s services. The impact of transceiver cost and maximum optical reach is assessed.
