Abstract

Asynchronous Transfer Mode (ATM) Networks are based on connections that are multiplexed dynamically on a single link. For satisfactory performance in an ATM network, congestion control is extremely necessary to guarantee the negotiated Quality of Service (QoS) for every connection. Traffic shaping is a congestion control mechanism that alters the traffic characteristics of a stream of cells on a connection to achieve better network efficiency by meeting the QoS objectives. We study a model for Traffic Shaping, Second Order Leaky Bucket, which consists of two leaky buckets to police the Sustained Cell Rate (SCR) and Burst Tolerance (BT) for each ATM connection. With this algorithm, ATM cells enter the first leaky bucket and the Cells conforming to the first leaky bucket enter the ATM network with Cell Loss Priority set to zero (CLP = 0). Any cell non-conforming to the first leaky bucket is sent to a second leaky bucket, and will be tagged CLP = 1 only if found to be non-conforming to the second leaky bucket. Cells conforming to the second leaky bucket are allowed to enter the ATM network with CLP = 0. We simulate the second-order leaky bucket for traffic shaping and show the effectiveness of second order leaky bucket in protecting the QoS experienced by connections passing through a common internodal link queue.
