Ž. Efficient and fair use of buffer space in an Asynchronous Transfer Mode ATM switch is essential to gain high throughput and low cell loss performance from the network. In this paper a shared buffer architecture associated with threshold-based virtual partition among output ports is proposed. Thresholds are updated based on traffic characteristics on each(More)
Computer network technologies have been growing explosively. Teaching computer networking principles can be enhanced using simulation through the use of interactive (not statistical based) simulation. The curriculum is based on the theory that through networking simulation programs, students are able to graphically implement the concepts learned in their(More)
The scheduling scheme of a switch affects the delay, throughput and fairness of a network and thus has a great impact on the quality of service (QoS). In Part I, we present a theoretical analysis of a burst scheduling for ATM switches and proved QoS guarantees on throughput and fairness of the applications. Here, we use simulation to demonstrate the(More)
Wireless LAN access networks show a strong potential in providing a broadband complement to Third Generation (3G) cellular systems. 3G networks provide a wider service area, and ubiquitous connectivity with low-speed data rates as compared to Wireless Local Area Networks (WLANs). WLAN networks offer higher data rate and the easy compatibility to wired(More)
—Bursts consist of a varying number of asynchronous transfer mode cells corresponding to a datagram. Here, we generalized weighted fair queueing to a burst-based algorithm with preemption. The new algorithm enhances the performance of the switch service for real-time applications, and it preserves the quality of service guarantees. We study this algorithm(More)
