The current best effort approach to quality of service in the Internet can no longer satisfy a diverse variety of customer service requirements , and that is why there is a need for alternative strategies. What the Internet needs is a mechanism for providing a fine-grained per-flow quality of service that does not cause network congestion and keeps overall(More)
The current best effort approach to Quality of Service in the Internet can no longer satisfy a diverse variety of customer service requirements, because of which there is a need for alternative strategies. A promising approach for dealing with this problem is a method called Load Distribution Scheme (LDS) which dynamically adjusts traffic load at the(More)
SUMMARY The problem of fair distribution of available bandwidth among traffic flows or aggregates remains an essential issue in computer networks. This paper introduces a novel approach, called the Exact Bandwidth Distribution Scheme (X-BDS), for dynamic and fair distribution of available bandwidth among individual flows. In this approach, the edge routers(More)
The national importance of creating "content reflecting cutting edge developments in STEM fields" has been recognized the National Science Foundation. The National Research Council has also noted that creating engaging laboratory and classroom experiences is a challenge to effective undergraduate education in STEM disciplines. In this paper we present our(More)
— Location-aided routing (LAR) is a mechanism which attempts to reduce the control message overhead of Ad-hoc on-demand distance vector (AODV) routing protocol by flooding only the portion of the network that is likely to contain the route to destination. LAR takes advantage of Global Positioning System (GPS) coordinates to identify a possible location of(More)
Despite numerous efforts, the problem of providing per-flow Quality of Service in a scalable manner still remains an active area of research. This paper introduces a scalable architecture for support of per-flow bandwidth guarantees, called the Bandwidth Distribution Scheme (BDS). The BDS maintains aggregate flow information in the network core and(More)
—In the world of amateur motorsports the racers are always looking to improve their skills. This has led to the development of various monitoring and data logging systems, often coupled with "action sports" cameras which capture the car performance in enough detail to allow the driver to study the race after completion. In this paper we investigate the(More)
The Bandwidth Distribution Scheme (BDS) [Hna03] was designed to combine the advantages of the Integrated and Differentiated Services models and to provide support for scalable per-flow Quality of Service. In recent studies Hnatyshin et al. showed that the variation of the Bandwidth Distribution Scheme called the Exact Requested Bandwidth Range BDS (X-BDS),(More)
In the recent year a variety of approaches for QoS support in the Internet such as Integrated Services [1], Differentiated Services [2], Bandwidth Distribution Scheme (BDS) [3], and others have been proposed. Most of the proposed approaches rely on the traffic policing unit, which may mark, delay, or drop packets that arrive above their reserved rate. The(More)
The current best effort approach to Quality of Service in the Internet can no longer satisfy a diverse variety of customer service requirements, and that is why there is a need for alternative strategies. In order to solve this problem a number of service differentiation approaches have been proposed. Unfortunately, these schemes are often inadequate for(More)
