Asynchronous transfer mode ATM networks must deene multicast capabilities in order to eeciently support numerous applications, such as LAN emulation, Internet protocol IP multicasting, video conferencing and distributed applications. Several problems and issues arise in ATM multicasting, such as signaling, routing, connection admission control, and traac(More)

We analyze the effect of providing a guaranteed rate to the UBR service class on the TCP performance over UBR. We describe an enhancement to UBR+ called the guaranteed rate service. Guaranteed rate service provides a minimum rate guarantee to the UBR traffic class. We examine effect of strict priority VBR over UBR traffic and show that the UBR performance(More)
Asynchronous transfer mode (ATM) networks must deene multicast capabilities in order to eeciently support numerous applications, such as video conferencing and distributed applications, in addition to LAN emulation (LANE) and Internet protocol (IP) multicasting. Several problems and issues arise in ATM multicasting, such as signaling, routing , connection(More)
This is a survey paper on the performance of TCP over ATM ABR and UBR services. Using throughput and fairness as our performance metrics, the effect of the following factors to the performance of TCP over ATM ABR and UBR is discussed here: (1)the switch dropping policies when overflow happens(simple discard, Tail Drop, Drop From Front, Early Packet Drop,(More)
We study the performance of Selective Acknowledgements with TCP over the UBR+ service category. We examine various UBR+ drop policies, TCP mechanisms and network configurations to recommend optimal parameters for TCP over UBR. We discuss various TCP congestion control mechanisms compare their performance for LAN and WAN networks. We describe the effect of(More)
Title: Performance analysis of ABR point-to-multipoint connections for bursty and non-bursty traac with and without VBR background Abstract: A numberof frameworks have been developed for extending ABR traac management algorithms to support point-to-multipoint connections. This contribution provides a comprehensive analysis of the performance of ABR traac(More)
We model World Wide Web (WWW) servers and clients running over an ATM network using the ABR service. The servers are modeled using a variant of the SPECweb96 [1] benchmark, while the clients are based on a model by Mah [2]. The traffic generated by this application is typically bursty, i.e., it has active and idle periods in transmission. Due to the fact(More)
