On the Automated Synthesis of Enterprise Integration Patterns to Adapt Choreography-based Distributed Systems

The Future Internet is becoming a reality, providing a large-scale computing environments where a virtually infinite number of available services can be composed so to fit users' needs. Modern service-oriented applications will be more and more often built by reusing and assembling distributed services. A key enabler for this vision is then the ability to automatically compose and dynamically coordinate software services. Service choreographies are an emergent Service Engineering (SE) approach to compose together and coordinate services in a distributed way. When mismatching third-party services are to be composed, obtaining the distributed coordination and adaptation logic required to suitably realize a choreography is a non-trivial and error prone task. Automatic support is then needed. In this direction, this paper leverages previous work on the automatic synthesis of choreography-based systems, and describes our preliminary steps towards exploiting Enterprise Integration Patterns to deal with a form of choreography adaptation.Comment: In Proceedings FOCLASA 2015, arXiv:1512.0694

Supporting Dynamic Service Composition at Runtime based on End-user Requirements

Network-based software application services are receiving a lot of attention in recent years, as observed in developments as Internet of Services, Software as a Service and Cloud Computing. A service-oriented computing ecosystem is being created where the end-user is having an increasingly more active role in the service creation process. However, supporting end-users in the creation process, at runtime, is a difficult undertaking. Users have different requirements and preferences towards application services, use services in different situations and expect highly abstract mechanisms in the creation process. Furthermore, there are different types of end-users: some can deliver more detailed requirements or can be provided with more advanced request interface, while others can not. To tackle these issues and provide end-users with personalised service delivery, we claim that runtime automated service composition mechanisms are required. In this paper we present the DynamiCoS framework, which aims at supporting the different phases required to provide end-users with automatic service discovery, selection and composition process. In this paper we also present the developed prototype and its evaluation

Creating agent platforms to host agent-mediated services that share resources

After a period where the Internet was exclusively filled with content, the present efforts are moving towards services, which handle the raw information to create value from it. Therefore labors to create a wide collection of agent-based services are being perfomed in several projects, such as Agentcities does. In this work we present an architecture for agent platforms named a-Buildings. The aim of the proposed architecture is to ease the creation, installation, search and management of agent-mediated services and the share of resources among services. To do so the a-Buildings architecture creates a new level of abstraction on top of the standard FIPA agent platform specification. Basically, an a-Building is a service-oriented platform which offers a set of low level services to the agents it hosts. We define low level services as those required services that are neccesary to create more complex high level composed services.Postprint (published version

Agent based Internet (WWW) services

The evolution of the World Wide Web heads towards the use of more and more intelligent services. A possible solution to implement this service oriented view of World Wide Web is to use agents. A framework is proposed to provide agent-based Internet services via WWW. A case study introduces the actual use of this framework and its relation to the agent technology. As an implementation effort the Personalized Home Page (PHP) system is presented here. investigates the application of this voting tool for rating purposes

Analysis of Security Service Oriented Architecture (SOA) with Access Control Models Dynamic Level

Now we are moving towards the "Internet of Things" (IOT) in millions of devices will be interconnected with each other, giving and taking information provided within a network that can work together. Because of computing and information processing itself IOT core supporters, So in this paper introduces "Service-Oriented Computing" (SOA) as one of the models that can be used. Where's it at each device can offer functionality as a standard service [4]. In SOA, we can make the resources available to each other in the IOT together. However, a major challenge in these service-oriented environment is the design of effective access control schemes. In SOA, the service will be invoked by a large number, and at the same time authentication and authorization need to cross several security domains are always used. In this paper, we present the analysis of data safety suatua WorkflowBased Access Control Model associated oriented (WABAC) to troubleshoot problems that occur within a system integration. The analysis showed that the point system function model based integration system that is lower than the legacy model of SOA-based systems, by designing several services using WOA approach. In addition, we have observed that the integrated model can guarantee the quality of service, security and reliability main, by applying SOA approach when needed. Finally, experimental results have proved that the service can be run side by side seamlessly without performance degradation and additional complexity

Adaptive data synchronization algorithm for IoT-oriented low-power wide-area networks

The Internet of Things (IoT) is by now very close to be realized, leading the world towards a new technological era where people’s lives and habits will be definitively revolutionized. Furthermore, the incoming 5G technology promises significant enhancements concerning the Quality of Service (QoS) in mobile communications. Having billions of devices simultaneously connected has opened new challenges about network management and data exchange rules that need to be tailored to the characteristics of the considered scenario. A large part of the IoT market is pointing to Low-Power Wide-Area Networks (LPWANs) representing the infrastructure for several applications having energy saving as a mandatory goal besides other aspects of QoS. In this context, we propose a low-power IoT-oriented file synchronization protocol that, by dynamically optimizing the amount of data to be transferred, limits the device level of interaction within the network, therefore extending the battery life. This protocol can be adopted with different Layer 2 technologies and provides energy savings at the IoT device level that can be exploited by different applications

Maturity model and action recommendation : A PSS capability self-assessment tool for companies

The main idea in Product-Service Systems (PSS) research is to provide solutions instead of products or services. Nevertheless, PSS comprise a broad variety of characteristics from product-oriented services, to use-oriented services and result-oriented services [1]. In industrial practice all of these dimension as well as intermediate stages are evidently realized. Additionally, trending topics like smart services, which can be described as the exploitation strategy from Industrie 4.0 [2], also known as cyber-physical systems and Internet of Things, accelerate the interest in PSS. However, many companies’ in particular small and medium-sized enterprises just started realizing the potential and necessity to establish service thinking in order to stay competitive. These companies face considerable challenges regarding the transformation from an Original Equipment Manufacturer (OEM) towards an Original Solution Provider (OSP)[3]. In a first step,companies need to assess their current situation and develop a strategy based on the desired target situation. For this reason, the authors developed a model combined with a self-assessment method which enables a basic analysis of the companies’ situation including action recommendations. The research results as well as the evaluation with a company are presented in this paper

The Next Generation of Internetworking

This paper describes a research effort concerned with the design of the next generation of internet architecture, which has been necessitated by two emerging trends. First, there will be at least a few orders of magnitude increase in data rates of communication networks in the next few years. For example, researchers are already prototyping networks with data rates of up to a few hundred Mbps, and are planning networks with data rates up to a few Gbps. Second, researchers from all disciplines of science, engineering, and humanities plan to use the communication infrastructure to access widely distributed resources in order to solve bigger and more complex problems. These trends provide new challenges and opportunities to researchers in the communication field. One such challenge is the design of what we call the very high speed internet (VHSI) abstraction which can help efficiently support guaranteed levels of performance for a variety of applications, and can cope with the ever increasing diversity of underlying networks with rapidly growing user population and needs. Our strategy towards achieving this ambitious goal comprises the following: • Design, specification, and prototype implementation of novel multipoint congram-oriented service that can work well with connection-oriented and datagram high speed networks, can provide variable grade service on a need basis to its applications, and can provide adequate reconfigurability to deal with survivability requirements due to network failures. • Design and implementation of gateway architecture than can support data rates of a few hundred Mbps, can interface with diverse networks, and can implement the congram-oriented service without becoming a performance bottleneck. • Development of analytical and simulation models to evaluate important tradeoffs associated with the design of a congram-oriented protocol, the resource management on diverse networks, and the design of new gateway architectures
