چکیده
Bin Zhou and M. Atiquzzaman Dept. of Electrical & Computer Systems Engineering Monash University, Clayton 3168, Australia. [email protected] Abstract A new analytical model of the nite cross-point bu ered multistage ATM switch under uniform and nonuniform tra c patterns is developed in this paper. Three scheduling policies for selecting a cell to be transmitted are compared. We have studied the impact of hot spot tra c on the performance of the switch. The effect of cross-point bu ering and output bu ering on the performance of the switch is also reported. The results from the model were validated with simulation results. It has been shown that the model provides very accurate results.

UBR+: Improving Performance of TCP over ATM-UBR Service
ATM-UBR switches respond to congestion by dropping cells when their bu ers become full. TCP connections running over UBR experience low throughput and high unfairness. For 100% TCP throughput each switch needs bu ers equal to the sum of the window sizes of all the TCP connections. Intelligent drop policies can improve the performance of TCP over UBR with limited bu ers. The UBR+ service propose...
متن کاملCost/Performance evaluation of Banyan networks for use in ATM switching fabrics
In this paper, we present a model for computing the cost of implementing Banyan networks. We limit our interest in Banyan networks which are used in ATM switching fabrics and are build in VLSI. The cost is given as a function of the characteristics of the network (ie. length of bu ers, speed of links, etc). We are focusing in this area because such networks have been used extensively in the des...

In this paper we study the design issues for improving TCP performance over the ATM UBR service. ATM-UBR switches respond to congestion by dropping cells when their bu ers become full. TCP connections running over UBR can experience low throughput and high unfairness. Intelligent switch drop policies and end-system policies can improve the performance of TCP over UBR with limited bu ers. We des...

متن کاملAnalysis of shared buer switches under non-uniform trac pattern and global ̄ow control
Shared buer switches do not suer from head of line blocking which is a common problem in simple input buering. Shared buer switches have previously been studied under uniform and unbalanced trac patterns. However, due to the complexity of the model, it was not possible to fully explore the performance of such a switch, in the presence of a single hot spot. In this paper, we develop a new m...
