We propose Alternative Best-E ort (ABE), a novel service for IP networks, which relies on the idea of providing low-delay at the expense of maybe less throughput. The objective is to retain the simplicity of the original Internet single class, best e ort service, while providing low delay to interactive, adaptive applications. With ABE, every best e ort(More)
This paper demonstrates the utility of typed shared data abstractions as an effective high-level means of structuring and coordinating parallel programs. Access to data shared by concurrent processes is expressed through operations of shared abstract data types (SADTs). SADTs abstract low-level concerns of communication and synchronization. The exposition(More)
Performance evaluation of TCP over ATM has been the focus of much research recently. A number of studies have analysed observed performance degradation, suggested ways to improve throughput, compared the performance of ABR and UBR as suitable classes of ATM service in transporting TCP traffic. With this explosion of studies exploring various combinations of(More)
The main purpose of the rate-based congestion control protocols that have been developed to support the deployment of real-time multimedia applications in the Internet is to ensure that the application’s traffic share the network in a fairly and friendly manner with the dominant TCP traffic. In this work we use the network simulator ns-2 to evaluate the(More)
