: wavelength assignment, light-tree protec tion, static traffic, dynamic traffic
In this paper, we address the wavelength assignment prob lem for light-tree protection under different traffic models. For static traffic, we formulate the problem mathematically and propose two new heuristics (tabu search and iterated hill-climber) to solve it. For dynamic traffic, in contrast to previous work, we analyze the traffic characteristics and propose a Low Cost First Serve (LCFS) strategy to maxi mize the gain and throughput of network systems. Numer ical results show our heuristics can achieve good perfor mance in terms of session blocking probability.
