....with each individual application include a set of parameters which are used to define network traffic characteristics such as peak rate, mean rate and mean burst length. The traffic descriptors are the key parameters in traffic shapping, admission control [11] and usage parameter control [12] (UPC) of an ATM network. Due to the limited availability of real traffic data gathered from existing ATM networks, researchers have not yet obtained good credible estimates of these descriptors. In order to study the traffic characteristics of ATM networks effectively, we conducted experiments to ....

....the simplest is the use of large buffers to hold the onslaught of cells during a period of congestion, and to allow a higher layer protocol to compensate for the cell loss that could occur during long periods of congestion. However, this was shown to be inadequate, and resulted in poor performance [24, 25]. One scheme that has been adopted and is currently in use in many of today s ATM switches is the Explicit Forward Congestion Indicator (EFCI) This is a binary approach, where a congested switch sets a single bit in the ATM cell header that indicates congestion in the network. As the network gets ....

....of smoothing. 1 Introduction Although the congestion control problem has been studied by researchers for a long time, satellite links coupled with ground network introduce a new dimension. For a good general discussion on the congestion control problem, see Yang and Reddy [11] Brett et al. [10], Jain [8] and Tanenbaum [9] The goal of our work regarding congestion control to date is twofold: 1. To address what congestion control approach best suits mixed ground satellite network (which may involve high speed ground network like ATM) engaging primarily in transmitting real time traffic. ....

....rate at which marked cells are transmitted is desirable. In sum, there are two buckets (one primary token bucket and one secondary token bucket; no leaky bucket is present here) in the virtual token buckets. The token buckets here in our implementation are without internal queue. Vickers et al. [10] provides a good discussion on this subject matter. 3.4.4 Multi buckets Algorithm By adding the concepts mentioned above to the concept of combining leaky bucket and token bucket in Section 3.4.2, we have the resultant three buckets algorithm which we term multi buckets algorithm. Of these ....

....Addressing the unique demands of bursty traffic is an important function of ATM traffic control. For the reasons mentioned above, many traffic control mechanisms developed for existing networks may not be applicable to ATM networks, and therefore novel forms of traffic control are required [8, 9]. One such class of novel mechanisms that work well in high speed networks falls under the heading of preventive control mechanisms. Preventive control attempts to manage congestion by preventing it before it occurs. Preventive traffic control is targeted primarily at real time traffic. Another ....
