Autonomic Brokerage Service for an End-to-End Cloud Networking Service Level Agreement
2014
8 pages; International audience; Today, cloud networking which is the ability to connect the user with his cloud services and to interconnect these services within an inter-cloud approach, is one of the recent research areas in the cloud computing research communities. The main drawback of cloud networking consists in the lack of Quality of Service (QoS) assurance and management in conformance with a corresponding Service Level Agreement (SLA). In this paper, we propose a framework for self-establishing an end-to-end service level agreement between a Cloud Service User (CSU) and multiple Cloud Service Providers (CSPs) in a cloud networking environment using brokerage service. We focus on Qo…
UMTS radio networks
2006
Publisher Summary This chapter reviews the contributions to the UMTS radio network planning, with the optimization being provided from COST 273 and the real-time tuning, which is related to RRM. The results on UTRAN performance evaluation by the means of simulation tools are also discussed. The UMTS planning includes processes like: the propagation and traffic models, the aspects of parameter planning, and the automatic planning algorithms. An accurate ray-tracing model integrated in a UMTS-capable planning tool allows the radio network planner to reach optimal numbers for the BS deployment and configuration while meeting the service level requirements. Ray tracing can identify the problem …
Service policies of German manufacturers: Critical factors in international competition
1992
Abstract German companies perform well in export markets, based on product quality and technology. But the competitive advantages and value-added of service are expected to grow sharply in the coming decade — especially product-focused service. Hermann Simon has identified ‘Hidden Champions’ in Germany — companies like Heidelberg Printing Machines, BMW and Mercedes-Benz, which integrate market and technology as equal driving forces and provide quick and reliable customer service. But there is much room for improvement in service provided by German manufacturing companies. They could upgrade their design and marketing of service, and apply better quality control such as setting quantitative …
Unit-level fairness and quality within the health care industry: A justice–quality model
2014
We test a justice–quality model in which peer justice and justice climate are related to the service quality provided by the work unit. Based on the effort–reward imbalance model, we propose that units perceiving fair treatment provide better delivery of the core service (functional service quality) and better relational service beyond the core service (relational service quality). We also test whether the cross-level relationship of high service quality delivered by work units translates into high customer ratings of the service quality they receive. Furthermore, we propose that high service quality increases the work unit’s influence on their customers’ quality of life (QoL). We test thes…
Towards global service level guarantee within autonomic computing systems
2011
International audience; In this paper, we specify a global service level guarantee including not only QoS but also security and taking into account user mobility. This global service level could be guaranteed within several autonomic computing systems managed by different autonomic domain managers. For that purpose, we propose an end-to-end Service Level Negotiation Protocol, called SLNP, to provide those autonomic managers with a negotiation capability. This allows achieving an agreement on the service level of each offered service between the different domains involved in the transport of that service. SLNP Implementation is made of Web Services technologies to enable interoperability in …
An effective opportunistic maintenance policy for a global service
2010
The aim of the present paper is to develop a model for an effective maintenance policy with refer to a global service contract between a services provider company and a company for the waste management. The contract requires, with fixed performance levels of the service, the supplying of a mandatory set of maintenance services on a set of waste compactors vehicles of the outsourcer company. In particular, the service provider (SP) must perform corrective maintenance actions and the replacement of the fault parts. The tackled problem concerns the determination of an effective opportunistic maintenance policy in order to assure the required service performance levels at the minimum global mai…
A global service level guarantee in NGN networks
2010
In this paper, we propose an end-to-end service level negotiation protocol which enables a global service offer covering quality of service (QoS) and security while taking into account user's mobility in this offer. This protocol provides all the domains involved in the transport of a various offered services with a negotiation capability to achieve an agreement on a service level. This paper shows also results of measurements evaluating the performances of the considered negotiation protocol and security impact on QoS.
