TL;DR: In this article, service quality research in traditional services and, more recently, in e-services tends to take a long time and is typically multichannel, whereas in virtual channels of delivery such as the Internet are typically multi-channel.
Abstract: Services employing virtual channels of delivery such as the Internet are typically multichannel. Service quality research in traditional services and, more recently, in e-services tends to take a s...

TL;DR: The Service Experience Blueprint (SEB) method is a multidisciplinary tool and terminology for service design that starts by studying the customer service experience to understand customer experience requirements for different service activities and how these requirements can be satisfied through alternative service interfaces.
Abstract: This article introduces the Service Experience Blueprint (SEB), a multidisciplinary method for designing multi-interface service experiences, and illustrates its application with two case examples ...

TL;DR: An analytical model is presented, in which most new features of the EDCA such as virtual collision, different arbitration interframe space (AIFS), and different contention window are taken into account, and based on the model, the throughput performance of differentiated service traffic is analyzed and a recursive method capable of calculating the mean access delay is proposed.
Abstract: The new standard IEEE 802.11e is specified to support quality-of-service in wireless local area networks. A comprehensive study of the performance of enhanced distributed channel access (EDCA), the fundamental medium access control mechanism in IEEE 802.11e, is reported in this paper. We present our development of an analytical model, in which most new features of the EDCA such as virtual collision, different arbitration interframe space (AIFS), and different contention window are taken into account. Based on the model, we analyze the throughput performance of differentiated service traffic and propose a recursive method capable of calculating the mean access delay. Service differentiation functionality and effectiveness of the EDCA are investigated through extensive numerical and simulation results. The model and the analysis provide an in-depth understanding and insights into the protocol and the effects of different parameters on the performance.

TL;DR: In this article, a distributed computing system using a data communications network may have a number of service providers for a given service or remote procedure call, and the name service maintains for each client or group of clients a configuration profile of the service providers in order to resolve the issue of selecting one of the several service providers when a request is made.
Abstract: A distributed computing system using a data communications network may have a number of service providers for a given service or remote procedure call. A client on the network makes reference to a name service to obtain the network address of one of these service providers. The name service maintains for each client or group of clients a configuration profile of the service providers in order to resolve the issue of selecting one of the several service providers when a request is made. A single configuration profile is a priority-ordered search list that maps from a service identifier (e.g., remote procedure call interface specification) into service provider (e.g., remote procedure call server) names. A configuration profile may include names for individual service providers, and/or named groups of service providers, and/or other configuration profiles. Configuration profiles are stored in a manner that makes them accessible throughout the distributed system, e.g., in the name service. Configuration profiles may be chained together by referencing other configuration profiles to provide a hierarchy of configuration profiles.

TL;DR: A framework for providing customers of Web services differentiated levels of service through the use of automated management and service level agreements (SLAs) is described, which was implemented as the utility computing services part of the IBM Emerging Technologies Tool Kit, which is publicly available on the IBM alphaWorksTM Web site.
Abstract: In this paper we describe a framework for providing customers of Web services differentiated levels of service through the use of automated management and service level agreements (SLAs). The framework comprises the Web Service Level Agreement (WSLA) language, designed to specify SLAs in a flexible and individualized way, a system to provision resources based on service level objectives, a workload management system that prioritizes requests according to the associated SLAs, and a system to monitor compliance with the SLA. This framework was implemented as the utility computing services part of the IBM Emerging Technologies Tool Kit, which is publicly available on the IBM alphaWorksTM Web site.
