有效的光传送网路由及波长分配算法

Efficient Routing and Wavelength Allocation Algorithms for Optical Transport Networks

研究了光传送网路由及波长分配问题,对于虚波长网络以波长优化为目的,给出了两种启发式算法,并提出了波长数减一代价,作为对算法另一评判依据,通过对仿真结果的分析,来研究所提出算法的有效性。

This paper discusses routing and wavelength assignment in optical network,In order to reduce the overall wavelength number required in Virtual Wavelength Path optical network with static traffic loading,two heuristic algorithms are proposed and a parameter called″one wavelength decrease cost″is defined and used to evaluate the performance of algorithms.We investigate the effectiveness of the two algorithms by simulating on computer.
