Abstract: This paper proposes active Virtual Circuit(VC) calculation method for traffic control of Asynchronous Transfer Mode(ATM) network Available Bit Rate(ABR) service, which is a rate-based traffic control scheme. The method based on ERICA algorithm can accurately calculate effective account of active sources according to VC’s active level, and allocate unused bandwidth among all ABR VCs. It shows the rule of Max-Min fair allocation, and ensures the efficiency and fairness of algorithm.

摘要：

ATM网络ABR业务流量控制是一种基于速率的流量控制机制。在ERICA算法的基础上，提出有效活动虚连接的计算方法，根据它们的活动度计算活动连接的有效数值，从而准确计算出处于活动状态的源端数，将未用带宽在ATM网络ABR连接之间公平且准确地进行分配，体现了Max-Min公平分配准则，能保证算法的高效性和带宽分配的公平性。
