摘要
波分复用技术结合时分复用形成了混合WDM EPON,如何提高系统的带宽利用率和用户服务质量成为关键技术。结合已有算法的优缺点,提出一种新的动态波长带宽分配算法。该算法结合业务等级分类和用户服务等级协议的权重为光网络单元分配相应的带宽和波长,以达到提高服务质量、带宽分配公平性,提高上行带宽利用率和改善网络性能的目的。
Wavelength division multiplexing technique combined with time division multiplexing form mixed WDM EPON.How to improve the system bandwith utilization and quality of service has become the key technology.Combined with the existing algorithms,this paper proposes a new dynamic wavelength and bandwidth allocation algorithm which allocates the bandwith and wavelength to the ONU based on different traffic types and SLA weights.The purpose of doing it is to improve the quality of service,utilization rate of the uplink bandwidth and fairness of bandwidth allocation.,and finally improve the performance of the network.
