中文摘要：

针对接入多维网关的异构网络因信道速率不同而引起的网络拥塞,在GPON技术的DBA算法和流控算法基础上,提出一种基于预测和分级轮询的动态带宽分配算法,并结合基于图形分类的令牌桶算法,通过对不同类型的服务进行动态带宽分配,实现流量控制。实验结果表明,该算法能有效地提高网关的服务质量。

英文摘要：

Aiming at network congestion of heterogeneous network accessing to multidimensional gateway caused by different channel rate,a dynamic bandwidth allocation algorithm based on prediction and grading polling is proposed according to DBA and flow control algorithm of GPON technology.Combining token bucket algorithm based on graphics categorization,flow control is realized by dynamic bandwidth allocation on different types of services.Experimental results show that the algorithm can improve effectively service quality of gateway.
