Recent congestion control protocols such as XCP and RCP achieve fair bandwidth sharing, high utilization, small queue sizes and nearly zero packet loss by implementing an explicit bandwidth share mechanism in the network routers. This paper develops new quantitative techniques for achieving the same results using only end-host measures. We develop new methods of computing bottleneck link charac...

In this work, we examine the downstream impediments of centralized Ethernet passive optical networks supporting LAN emulation [inter-Optical Network Units communication(ONU)]. The available downstream bandwidth in the centralized scheme is reduced due to LAN emulation and upstream bandwidth allocation functions. The reduction in available downstream bandwidth results in degraded downstream perf...

The task of supporting integrated multi-rate multimedia traffic in a bandwidth poor wireless environment poses a unique and challenging problem for network managers. In this paper we propose a novel bandwidth allocation strategy which partitions the available bandwidth amongst the different traffic classes in a manner that ensures quality of service (QoS) guarantees for digital video while mini...

-For emerging Internet services and contents in the traffic-sharing environment of limited bandwidth capacity, an efficient method is required to manage the Internet-sharing problem and to improve quality of service (QoS) for highdemand bandwidth users. The results of our study show that dynamically delaying un-attended Internet usage activities, such as large file downloading, will drive more ...

Good quality video services always require higher bandwidth. Hence, to provide the video services e.g., multicast/broadcast services (MBSs) and unicast services along with the existing voice, internet, and other background traffic services over the wireless cellular networks, it is required to efficiently manage the wireless resources in order to reduce the overall forced call termination proba...

This work proposes two enhanced multiple mobile subscriber stations (MSSs) power-saving scheduling methods for IEEE802.16e broadband wireless networks. The proposed methods are designed for the Unsolicited Grant Service (UGS) of IEEE802.16e. To reduce the active periods of all power-saving MSSs, the base station (BS) allocates each MSS fewest possible transmission frames to retrieve its data fr...

Several classes of applications with abundant fine-grain parallelism, such as media and signal processing, graphics, and scientific computing, have become increasingly dominant consumers of computing resources. Prior research has shown that stream processors provide an energy-efficient, programmable approach to achieving high performance for these applications. However, given the strong compute...

A growing set of applications require digital audio and video data, commonly referred to as continuous media (CM). These applications require continuous real{time data ow during play-back and recording. Scheduling strategies to service accesses by multiple concurrent applications at CM data servers (CMS) must provide timely access to storage devices. Besides real{time access, such data is chara...
