摘　　要：提出了一种基于贝叶斯算法的XG-PON业务感知机制,该机制采用贝叶斯算法对业务进行分类,以实现高效的业务感知。在此基础上通过OLT与ONU的交互,优化XG-PON的资源分配。对基于贝叶斯算法的XG-PON业务感知机制进行仿真,仿真结果表明该机制能有效降低丢包率并缩短时延,提高了系统对多业务的支持能力。The paper proposes a Bayesian algorithm Enabled Service-Aware mechanism in XG-PON, the mechanism uses the Bayesian algorithm to classify services, in order to match services requirements with better efficiency. Thus, resources allocation optimization is enabled through cooperation between OLT and ONUs. Simulation of the scheme is conducted, the results show that this proposed approach can greatly improve the supporting ability for multiple services, effectively reduces the packet loss rate and shortens the time delay.
