Effectiveness of virtual concatenation alghorithms for next generation SDH/SONET networks

摘要

The paper presents a hybrid mechanism for virtual concatenation (H-VCAT), which allows increasing channel utilizing by 10% compared with virtual concatenationand by 50-70% in comparison with contiguous concatenation. The evaluation of network parameters at the stage of optical transport system designing provided. The optimum set of containers for transferring traffic from FTTx access networks with 99.7% channel utilizing was proposed.
