DTBF模型的流量负载均衡研究与实现

Research and Implementation on Traffic Load Balance Based on DTBF

针对目前网络工程中负载优化困难的问题,基于令牌调度方法提出了一种改进的动态令牌分配调度模型DTBF,实现了实时流的流量整形,推导并设计了动态分配令牌的优化算法以解决逻辑链路间的负载均衡问题。实验分析和工程实现结果表明,此流量调度方法能有效地对链路间进行流量负载均衡,显著提高带宽利用率,用户公平性良好。

An improved distribute token bucket filter schedule model called dynamic-distribute token bucket filter （DTBF） is proposed to solve the problem of traffic balance and real-time traffic shaping. The algorithm of DTBF in multi-link networks is also designed and implemented for load balance. Simulation experiments and implementation indicate that the DTBF can balance the traffic of multi-uplinks effectively. Bandwidth utilities of links increase, fairness and adaptability are favorable.
