TLDR
This paper forms the trust-based resource allocation problem as an optimization problem under SLA constraints, and it is solved using an efficient numerical procedure.Abstract:
With the number of e-Business applications dramatically increasing, service level agreement (SLA) will play an important part in Web services. A SLA is a combination of several quality of services (QoS), such as security, performance, and availability, agreed between a customer and a service provider. Most existing research addresses only one QoS metric, and in the case of the response time, the average time to process and complete a job is typically used. In this paper, we study trustworthiness, percentile response time and availability. We consider all these qualities for a trust-based resource allocation problem which typically arises in Web services applications. We formulate the trust-based resource allocation problem as an optimization problem under SLA constraints, and we solve it using an efficient numerical procedure.read more

A trust-based game theoretical model for Web services collaboration
TL;DR: A trust-based game theoretical model for Web services collaboration that provides a metric for the assessment of the collaboration trust shows that the use of the trust allows a safer collaboration with respect to a game where there is no consideration of theTrust as a criteria for allocating tasks.

Personalized Services Recommendation Based on Context-Aware QoS Prediction
Li Kuang,Yingjie Xia,Yuxin Mao +2 more
TL;DR: A new method dubbed CASR (Context-Aware Services Recommendation) is proposed by referring to previous service invocation experiences under similar context with the current consumer, which is of great importance in the personalized service recommendation system.

SLA-Based Service Composition in Enterprise Computing
Kaiqi Xiong,Harry G. Perros +1 more
TL;DR: A novel framework for a QoS-constrained resource provisioning problem is presented, and a capacity planning approach to optimizing computer resources for all service sites owned by service providers subject to multiple QoS metrics defined in the SLA and their violation penalties is proposed.

Bandwidth estimation for video streaming under percentile delay, jitter, and packet loss rate constraints using traces
Bushra Anjum,Harry G. Perros +1 more
TL;DR: A CPU-efficient activity-based simulation model is presented and it is shown that the bandwidth required for n identical video streams that follow the same path through an IP network, so that the end-to-end percentile delay remains the same, is a linear function of n.

QoS issues in Web services
TL;DR: QoS measures can include the maximum throughput or a function that describes how throughput varies with load intensity, which can be measured in terms of arrival rates (such as requests per second) or number of concurrent requests.
