And Performance

Traditionally, network Service Providers specify Service Level Agreements (SLAs) to guarantee service availability and performance to their customers. However, these SLAs are rather static and span a single provider domain. Thus, they are not applicable to a multi–domain environment. In this paper, the authors present a framework for automatic creation and management of SLAs in a multi-domain environment. The framework is based on Service Oriented Computing (SOC) and contains a collection of web service calls and modules that allow for the automatic creation, configuration, and delivery of an end-to-end SLA, created from the merging of the per-domain SLAs. This paper also presents a monitoring procedure to monitor the QoS guarantees stipulated in the SLA. The SLA establishment and monitoring procedures are tested through a Grid application scenario targeted to perform remote control and monitoring of instrument elements distributed across the Grid.

Service Migration

This article provides a proof-of-concept of the applicability and reusability of the authors proposed framework for web service migration through a traffic jam detection case study. The framework migrates mobile hosted web services between mobile vehicles using context-aware self-adaptive mechanism in order to guarantee service availability and quality. A decision-making process is implemented to select the best destination vehicle from between the found possible migrations based on prioritized criteria set.
