摘要 许多基于队列的机制被提出,用于对带宽进行管理控制,以解决带宽分配和流量负载均衡问题。但是,它们在实际应用中没有消除链路层流控对传输层性能的影响,对TCP性能造成一定的下降,使带宽利用率不够高。本文首先给出基于令牌分配的流量数学模型,设计了一种基于动态分配令牌的优化算法来解决逻辑链路间的流量控制问题,然后利用已有的"公平队列"技术来解决控制带宽资源的使用问题,并给出了相关的产业化研究和讨论。 Many guarantee mechanisms based on queueing for controlling bandwidths and load balancing are proposed, unluckily they can not avoid the effect from the control of the link layer on the transport layer, which makes the performance of TCP decrease. This paper describes an optimal algorithm based on dynamically allotting tokens for traffic control among logical links, gives a method of controlling the bandwidth using the traditional technology of "Fairness Queueing", and makes some discussions on its industrialization.
