中文摘要：
文章研究了波分复用（WDM）光网络中动态业务下的波长分配问题，在无波长转换器的条件下，提出了一种加入了公平性考虑的动态门限算法。该算法在支持多优先级的动态门限法的基础上，通过更新初始优先级减少了不同距离光路连接请求问的阻塞率差别，改善了公平性。计算机仿真结果说明了该算法的有效性。
英文摘要：
In this paper, wavelength assignment in WDM optical networks with dynamic traffic is studied and a fair priority-based dynamic threshold algorithm for wavelength assignment without wavelength conversion proposed. By using this algorithm, the difference in blocking rates among lightpath connection requests for different distances is reduced by updating the initial priority levels and fairness in the wavelength assignment improved. Simulation results show that the proposed algorithm is effective.
