浅析QoS中的令牌桶算法

摘要

It researches token bucket algorithm in QoS field, expounds the implementation model of end-to-end QoS technology, intro-duces the token bucket algorithm in traffic shaping, gives details on single-rate and double-rate token bucket algorithm. It also analyzes the token bucket algorithm on MQC platform. In the LTE era, as the appearance of new service with high-bandwidth and low-delay, the fine-grained management of traffic based on the token bucket algorithm has become the new topic in the QoS field.%对QoS领域中的令牌桶算法进行了研究，首先对端到端QoS技术的实现方式进行了阐述，然后介绍了流量整形中的令牌桶算法，并且对单速双桶和双速双桶令牌桶算法进行阐述和分析。最后对MQC平台实现令牌桶算法进行分析。在LTE时代，由于大带宽需求、业务低时延要求的新型业务不断出现，基于流量整形的令牌桶算法应用可以应对上述问题而成为QoS研究的新热点。
