摘 要: 为了优化多重链路多业务环境下的时延,首先分析了带宽分配及链路中数据传输时延计算方法,提出一种时延优化的动态可用带宽分配算法(DODBA)。该算法基于不同优先级业务的时延比较实现了剩余可用带宽的重新分配。仿真实验证明了DODBA的有效性,能控制各链路不同业务的时延,并提高了系统带宽资源的利用率。DODBA可用于解决大型宽带网络接入控制中的实际问题。 In order to optimize the delay feature in multiple links and services environment,this paper analyzed the calculate method of bandwidth allocation and data transmission delay,and proposed an algorithm for dynamic available bandwidth allocation based on delay optimization(DODBA),it realized residual available bandwidth reallocation and guaranteed the delay respond of high priority level business.Simulated experiments prove that DODBA is effective and can control the services delay and improve utilization ratio of system bandwidth is proved to be effective.It can be used to solve the control problems in large-scale broadband access network.
