通过研究OFDMA-PON中基于区分服务的资源分配算法，提出固定子载波分配和动态子载波分配两种算法，针对其中的参数进行研究并对二者的性能进行了比较。结果表明，两种算法均可以保证高优先级业务的性能，固定分配算法计算复杂度低，更适合高负载网络；动态子载波分配算法则在低负载时能有效提升系统性能。

Subcarrier assignment algorithms for OFDMA PON are discussed in this paper considering differen-tiated services. Fixed and Dynamic assignment schemes are proposed and several important parameters are studied. Although dynamic scheme has much greater computational complexity than fixed scheme, it could achieve lower packet delay and higher channel utilization.
