多链路接入网中带宽分配的切换会造成较大的系统负载和时延增加,为优化各业务的动态带宽请求和全网效能,提出一种基于业务的带宽分配架构,设计了支持多Qo S参数约束切换的动态带宽分配方法(MQCCDBA),方法实现了Qo S约束值和带宽切换代价的计算,并量化了满足约束条件下带宽分配的大小,仿真结果验证了MQCCDBA能在满足一定Qo S约束条件下控制带宽分配切换次数,有效地减少系统负载和数据包时延,提高系统带宽利用率,MQCCDB可用于解决大规模网络环境下多业务的复杂Qo S控制实际问题.
The switching of bandwidth allocation in multi-link access network will cause greater system load and delay. To optimize the dynamic bandwidth request and the whole network efficiency of each service, a service-based bandwidth allocation architecture is proposed, Qo S parameter constrained switching dynamic bandwidth allocation method (MQCCDBA). The method realizes the calculation of the Qo S constraint value and the bandwidth switching cost, and quantifies the size of the bandwidth allocation under the constraint condition. The simulation results verify that MQCCDBA can meet the requirements of Qo S constraint, the number of switching of bandwidth allocation is controlled effectively to reduce system load and packet delay and improve system bandwidth utilization. MQCCDB can be used to solve the practical problem of complex QoS control in multi-service under large-scale network environment.
