摘　　要：介绍了基于动态波长分配的WDM-PON的运行原理,结合已有算法的优缺点,提出了一种新的区分业务等级的动态带宽分配算法。新算法对不同的业务区分等级,并把波长资源优先分配给高优先级,在保证服务质量的下提高了上行带宽的利用率。The article describes the operating principle of WDM-PON based on dynamic wavelength assign- ment,combined with the advantages and disadvantages of existing algorithms,a novel dynamic wavelength al- location is proposed,which supports differentiating service levels.The novel allocation on a different level of service differentiation, and the wavelength resources priority assigned to high-priority,which not only ensures the quality of service but also improves the efficiency of up-link bandwidth.
