Thin Client Computing Solutions in Low- and High-Motion Scenarios

Abstract: The centralized thin client computing environment offers a solution to the vulnerability of desktops to viruses, trojan horses and worms. It also releases the user from regular software and hardware updates. One of the major barriers for the proliferation of thin clients in public wide-area networks is the hampering presentation of multimedia applications. While the existing remote display protocols offer a good user experience for office applications, most protocols cannot deal with swift display updates, like video playback, or hardware-accelerated 3D-graphics as in games. In this paper, a wide range of well-known and widely used thin client protocols are tested in both low-motion and high-motion scenarios. It is shown that additional functionality is required to offer a satisfying multimedia experience.

PadicoTM: An Open Integration Framework for Communication Middleware and Runtimes

Abstract: Computational grids are seen as the future emergent computing infrastructures. Their programming requires the use of several paradigms that are implemented through communication middleware and runtimes. However some of these middleware systems and runtimes are unable to take benefit of the presence of specific networking technologies available in grid infrastructures. In this paper, we describe an open integration framework that allows several communication middleware and runtimes to efficiently share the networking resources available in a computational grid. Such framework encourages grid programmers to use the most suited communication paradigms for their applications independently from the underlying networks. Therefore, there is no obstacle to deploy the applications on a specific grid configuration.

Performance Prediction of Service-Oriented Applications based on an Enterprise Service Bus

Abstract: An enterprise service bus (ESB) is a standards-based integration platform that combines messaging, web services, data transformation, and intelligent routing in a highly distributed environment. The ESB has been adopted as a key component of SOA infrastructures. For SOA implementations with large number of users, services, or traffic, maintaining the necessary performance levels of applications integrated using an ESB presents a substantial challenge, both to the architects who design the infrastructure as well as to IT professionals who are responsible for administration. In this paper, we develop a performance model for analyzing and predicting the runtime performance of service applications composed on a COTS ESB platform. Our approach utilizes benchmarking techniques to measure primitive performance overheads of service routing activities in the ESB. The performance characteristics of the ESB and services running on the ESB are modeled in a queuing network, which facilitates the performance prediction of service oriented applications. This model is validated by an example ESB based service application modeled from real world loan broking business application.

A Case Study in Applying a Product Line Approach for Car Periphery Supervision Systems

Abstract: Car Periphery Supervision (CPS) systems comprise a family of automotive systems that are based on sensors installed around the vehicle to monitor its environment. The measurement and evaluation of sensor data enables the realization of several kinds of higher level applications such as parking assistance or blind spot detection. Although a lot of similarity can be identified among CPS applications, these systems are traditionally built separately. Usually, each single system is built with its own electronic control unit, and it is likely that the application software is bound to the controller’s hardware. Current systems engineering therefore often leads to a large number of inflexible, dedicated systems in the automobile that together consume a large amount of power, weight, and installation space and produce high manufacturing and maintenance costs. This paper reports on an initiative undertaken by the Bosch Group in applying a product line development approach to develop CPS systems economically. Product line development represents a multi-system engineering approach which takes common and variable aspects between systems in the same application domain into account. It provides a basis to develop a line of products economically based on a common system architecture and reusable components. A product line allows the degree of reusability to be optimized across different systems while simultaneously preserving the overall quality. This supports the need to develop more integrated and flexible multi-functional systems quickly and cost-effectively. The purpose of this paper is to report on the experiences and results obtained from a case study in developing a product line of CPS systems.

Computing environment configuration

Abstract: Within a computing environment, an application may run in a variety of contexts, e.g., as a natively executable application, as a client-side interpretable application embedded in a web browser, or as a server-side application that communicates with the user through a web interface presented on a device. The application may also access resources of the computing environment stored on multiple devices. The configuration of the application to operate equivalently in these diverse environments may be facilitated by representing the application within an object hierarchy representing the computing environment. The application may be configured to operate on the objects of the object hierarchy regardless of the location of the stored objects, to execute on any device, and to execute upon a standard set of application programming interfaces. The configuration of the application in this manner promotes the versatility of the application in operating equivalently in different programming contexts.
