FlexiNet - QoS Investigation

نویسنده

  • Oyvind Hanssen
چکیده

In this report we investigate what are the main concepts and issues in the support of Quality of Service, focusing at open distributed computing and middleware platforms. We study how these issues are being addressed in research on QoS support related to middleware. QoS is about non-functional properties in general, but research has been centred around communication protocols and multimedia. The main issues of QoS, related to each RM-ODP viewpoints are discussed. Important issues are QoS specification, QoS provision and how to deal with changing conditions. Research in QoS in middleware platforms is mainly centred around ODP, ANSA and CORBA architectures. Distribution: Supersedes: Superseded by: APM.1977.01.00 Approved 02 June 1997 Technical Report

Developing an Electrified Fence to Exclude Rabbits from Crops

The effectiveness of a new design of electric strained wire fence (CSL fence) for managing rabbits is currently being assessed in a two year trial. It is being compared with a commercially available electric netting fence (Flexinet fence) and also with farmers' normal control methods. The study is taking place on commercial farms in Cornwall, England, where the fences are being erected to prote...

Multiple Language Family Support for Programmable Network Systems

Various programmable networks have been designed and implemented during the last couple of years. Many of them are focused on a single programming language only. This limitation might—to a certain extend—hinder the productivity of service modules being programmed for such networks. Therefore, the concurrent support of service modules written in multiple programming languages was investigated wi...

QoS-Based web service composition based on genetic algorithm

Quality of service (QoS) is an important issue in the design and management of web service composition. QoS in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. In recent years, the number of available web services has proliferated, and then offered the same services increasingly. The same web ...

Advanced operations research techniques for multi-constraint QoS routing in internet

Internet Traffic has grown exponentially over last few years due to provision of multiple class services through Internet backbone. With the explosive use of Internet, contemporary Internet routers are susceptible to overloads and their services deteriorate drastically and often cause denial of services. In this paper, an analysis is made how forecasting technique, routing algorithm and Genetic...
