Describing and selecting communication services in a service oriented network architecture

Abstract: Today networks offer communication services ranging from a rather simple and unsecure one to secure and reliable data transmission for communicating on the network In the future, it is expected that networks will offer a large number of different communication services With so many services available, determining which service to select and use becomes much more difficult Here we propose a description schema including an ontology for describing communication services For service selection a decision making process called Analytic Hierarchy Process (AHP) is utilized which is specially adapted and extended for automatic processing

Towards QoS in Internet of Things for Delay Sensitive Information

Abstract: Ensuring QoS for transmission of delay sensitive information is of paramount importance in network of smart devices formally known as Internet of Things (IoTs). The most commonly used Best Effort service model cannot be an attractive mechanism to treat delay sensitive traffic. Heterogeneous smart devices with limited buffer capacity needs effective buffer management scheme and differentiated service priorities to provide preferential treatment to delay sensitive traffic. This paper proposes a cost-effective analytical model for a finite capacity queueing system with pre-emptive resume service priority and push-out buffer management scheme. The analytical model can be used to predict the performance of smart devices under various traffic conditions that meet the required QoS constraints of IoT devices.

Alternative representations for end user composition of service-based systems

Abstract: Service composition is a process of developing service-based applications that combine the functionality and features from multiple service providers in a unified solution In this paper we report on a study aimed to gauge users' views and perceptions about traditional service composition approaches (such as control flow and data flow-based composition approaches) versus a system assisted composition approach User preferences and opinions are obtained from a set of focus groups that aimed at exploring the mental model of end-users about the way they would prefer to develop service-based applications The results of user studies are being used in the design of an easy to use service-based application development tool in the EC funded SOA4All project

Service selection in web service compositions optimizing energy consumption and service response time

Abstract: A challenging task in Web service composition is the runtime binding of a set of interconnected abstract services to concrete ones. This question, formulated as the service selection problem, has been studied in the area of service compositions implementing business processes. Despite the abundance of work on this topic, few of them match some practical needs that we are interested in. Indeed, while considering the business process implemented by service compositions, we can distinguish between two classes: compositions that correspond to single business process and those implementing multiple communicating processes. While most of the prior work focuses only on the first case, it is the latter that interests us in this paper. This paper contributes to the service selection by proposing a new algorithm that, in polynomial time, generates a mixed linear integer program for optimizing service compositions based on the service response time and the energy consumption. The novelty in this work is our focus on multi-process composition and energy consumption. The paper also proposes a new analysis of the service selection and an evaluation of the proposed algorithm.

System and method for differentiated service levels in an internet protocol television network

Abstract: Various embodiments of the inventive subject matter provide a framework that may be used to provide service level differentiation in an IPTV delivery system based on program content for any given television channel or programming. For example, for the same TV channel, different service levels may be offered and provided, with each level of service offering to individual subscribers. For example, in one embodiment service levels may be provided by varying the number and duration of commercials or the amount of display space afforded to commercials, value-added content and/or entertainment content in a particular channel. Accordingly, the systems and methods hereof allow service providers flexibility to provide IPTV advertisement and value-added content services. This service differentiation can be used to attract different levels of subscribers, increasing the penetration ratio of IPTV services, facilitate the delivery of effective advertisements to target subscribers, and/or increase revenue. In some cases, some subscribers will pay more money to watch TV with fewer ads and more value-added content. Other subscribers may be agreeable to watching more ads if they can receive TV for less money. Thus, providing customized live TV delivery service is may enable IPTV providers to improve penetration ratio and increase revenue.
