A New Mechanism for Available Bandwidth Estimation [PDF]
Journal of Convergence Information Technology, 2009 In this paper, a new mechanism for available bandwidth estimation is proposed to improve the estimation accuracy compared with the existing IGI(Initial Gap Increasing)/PTR(Packet Transmission Rate) mechanism. The proposed mechanism defines three cases of the difference between the average output gap and the input gap, and then reflects fully them ...

Distributed bandwidth reservation by probing for available bandwidth
The 11th IEEE International Conference on Networks, 2003. ICON2003., 2004For many applications in Internet protocol-based networks a guaranteed quality of service is crucial. A simple and scalable way of achieving this is to use the differentiated services architecture in conjunction with admission control. In this research, we focus on the reservation of bandwidth by routers on the edge of a single network domain with ...

Difficulties in Estimating Available Bandwidth
2006 IEEE International Conference on Communications, 2006Available bandwidth estimation is very important for network operators, users, and bandwidth-sensitive applications. In the last 15 years, a large number of techniques and software tools have been introduced to estimate the available bandwidth actively. Many of them were verified in simulation and over a limited number of Internet paths.

Estimation of the Available Bandwidth in Inter-Cloud Links for Task Scheduling in Hybrid Clouds
IEEE Transactions on Cloud Computing, 2019In hybrid clouds, inter-cloud links play a key role in the execution of jobs with data dependencies. Insufficient available bandwidth in inter-cloud links can increase the makespan and the monetary cost to execute the application on public clouds ...

Bandwidth availability of multiple-bus multiprocessors
IEEE Transactions on Computers, 1985The effect of failures on the performance of multiple-bus multiprocessors is considered. Bandwidth expressions for this architecture are derived for uniform and nonuniform memory references. Mathematical models are developed to compute the reliability and the performance-related bandwidth availability (BA).

On the bandwidth availability of multistage interconnection networks
1993 Euromicro Workshop on Parallel and Distributed Processing, 2002In this paper, we develop a model that describes the behaviour of a multistage interconnection network (MIN) interconnecting processors and memory modules, when faults exist among the functional units (the processors, memory modules, switching elements and links).

On measuring available bandwidth in wireless networks
2008 33rd IEEE Conference on Local Computer Networks (LCN), 2008BART is a state-of-the-art active end-to-end bandwidth measurement method that estimates not only the available bandwidth but also the link capacity of the bottleneck link. It uses a Kalman filter to give estimates in real time during a measurement session. In this paper, we have studied the impact of 802.11 networks on the bandwidth estimates produced

Towards multihop available bandwidth estimation
ACM SIGMETRICS Performance Evaluation Review, 2009We evaluate the algorithm proposed in [1], which estimates the residual bandwidth on each hop of an Internet path using a para-metric model which consists of a Kelly queueing network. The evaluation is driven by simulation based on real network traces over a two node path. Correction factors are proposed and evaluated to cope with deviations from model

An Algorithm for Available Bandwidth Measurement
2001In this paper, we present an algorithm for available bandwidth measurement of a path between two hosts as well as some preliminary simulation results. The measurement algorithm is based on active probing with two techniques we have developed: variable speed probing and zoom-in/zoomout. Compared with previous work, the algorithm has the advantage of low

Bandwidth availability of multiprocessor systems
Microelectronics Reliability, 1994Abstract Multiprocessors are non-failure critical systems and therefore various reliability measures cannot properly evaluate these systems. For such systems bandwidth availability is the most appropriate measure. This paper presents equations for computing bandwidth availability of three types of multiprocessors, namely multiple bus, crossbar and ...
