一种自适应RIO算法的研究

An adaptive RIO algorithm in DiffServ network

针对区分服务保证转发服务中传输流间带宽分配公平性的问题,本文提出一种自适应RIO(ARIO,adaptive RIO)算法。仿真结果表明,ARIO算法不但可以在不同订购条件下获得更高的带宽利用率和更低的分组丢失率,而且有效地改进了原RIO算法的剩余带宽公平性问题。

An adaptive RIO algorithm (ARIO) is proposed for the bandwidth fairness problem in bandwidth allocation among flows for assured forwarding service in DiffServ network. Simulation results show that adaptive RIO can not only achieve higher link utilization and lower loss ratio under various subscription conditions, but also effectively improve the fairness of original RIO in terms of excess bandwidth allocation.
