中文摘要	A lightpath-estimation-based differentiator service mechanism is proposed for overlay IP/WDM networks. The existing methods proposed in literatures, which selectively block lower priority traffic using wavelength consumption information, cannot be applied in the circumstance that the IP/MPLS layer is unaware of physical hop counts of lightpaths. The proposal estimates physical hop counts of lightpaths with a lightpath differentiation scheme, estimates the amount of wavelength resources that connections consume, and rejects lower priority connection requests which occupy large amounts of wavelength resources. Simulation results show the mechanism can effectively provide differentiator service for traffic of different priorities.
