Paper Abstract

Packet Ring transport technology combines the simplicity of Ethernet and survivability of SONET and attracts more and more interests of researches. However, electrical processing cost will also be very high as data rate grows to gigabit level, which lowers its efficiency. This paper examines the value of optical bypass approach by minimizing the traffic to be processed in electrical domain. An Integer Linear Program (ILP) formulation is presented to solve this problem and results with different traffic patterns are given, which shows one more wavelength can bring notable electrical processing cost savings in the case of a small number of multiplexed wavelengths in one channel.
