摘要
结合现有的GPON中DBA算法,遵照ITU-T规范,提出一种结合可变轮询周期和流量预测的XG-PON动态分配算法。这种DBA算法,支持多种QoS业务,并充分考虑业务的突发性,能准确的预测下一时刻的带宽。最后,对提出的DBA算法性能进行了简单仿真分析。
Basing on the existing GPON DBA algorithm,this paper proposed variable polling period and predicted flow dynamic allocation algorithm for XG-PON according ITU-T norms.This algorithm can support various QoS services,and fully considers sudden businesses,can accurately predicts bandwidth in next moment.The auther give a brief analysis of the simulation results of the algorithm.
