The composition of services in the web of objects poses important challenges concerning resources limitation, adaptability, performance and scalability. In this paper, we focus on the optimization of service selection as the key operation in dynamic service composition by using multi-agent architecture that achieves an online generation and rescheduling of the optimal services execution workflow by...
QoS (Quality of Service) guarantee has emerged as one of the most important technologies for the grid computing. Because the existing QoS control systems focus on designing independent executive management system, some problems still remain to be addressed, including low efficiency, bad scalability, and inadequate QoS automatic control. To address the above problems, this paper presents a novel SLA-driven...
This paper presents a purely empirical approach to estimating the effective bandwidth of aggregated traffic flows independent of traffic model assumptions. The approach is shown to be robust when used in a variety of traffic scenarios such as both elastic and streaming traffic flows of varying degrees of aggregation. The method then forms the basis of two quality of service related traffic performance...
In order to realize the core networks of the future utilizing the translucent or transparent optical networks the DICONET vision is presented in this article. Providing ultra high-speed end-to-end connectivity with quality of service and high reliability through the exploitation of optimized protocols and lightpath routing algorithms that will complement a flexible control and management plane is...
