The Internet can not keep up with changing application requirements and new network technologies as its network architecture makes it hard to introduce new functionality because existing functionalities in the Architecture are inherently tightly coupled. This article describes how the principles of Service Oriented Architecture (SOA) can help to develop more flexible network architecture. We argue...
Enterprise Cloud Computing has the complicated issues of the multi-tenancy, cross layer service composition, i.e., Software as a Service, Platform as a Service, and Infrastructure as a Service, multiple constraints from user requirements and Service Level Agreements. To assure the quality of service and effectiveness of Enterprise Cloud Computing, a middleware to support the service composition and...
The Smart Client is a system of network distribution, one of which important advantages is occasionally connected. It allows users to continue working where it can not connect the network resources. This paper focuses on the service-oriented occasionally connected smart client architecture, data cache, data management and other key technologies. And through the application of worker examination management...
Active learning or working by means of online laboratories is especially valuable for distance working or education. Users in the workplace can access remote laboratories without having to travel. This flexibility is important for teleworking, education and lifelong learning. The implementation and maintenance of online labs is expensive and partially associated with high administrative efforts. These...
Service-Oriented Architecture approach is extended gradually from the enterprise level to the device level. It encapsulates the functions of devices in the form of web services in the device layer in order to enhance the interoperability and openness between devices. However, most of the embedded services are deployed relying on human intervention rather than deployed automatically, due to different...
The proliferation of remote laboratories in multiple disciplines of science has removed the cost and administration burdens that hinder the adoption of practical sessions in engineering education. Remote laboratories provide online workbenches unconstrained by neither temporal nor geographical considerations and allow an interactive learning that maintains student attention. Recently, remote laboratories...
Software systems are becoming more and more complex due to the integration of large scale distributed entities and the continuous evolution of these new infrastructures. All these systems are progressively integrated in our daily environment and their increasing importance have raised a dependability issue. While Service oriented architecture is providing a good level of abstraction to deal with the...
In Service-Oriented Architecture, a service contains a set of operations with openly defined input and output parameters. In addition to these operations and traditional QoS, offered services need to implement different levels of intrusion tolerance. Indeed, intrusion tolerance has been recently presented as part of the defense-in-depth solution in order to enhance security resilience for services,...
The current growth in embedded ICT infrastructure, driven by visions such as the "Smart Cities" concept, is leading to the deployment of a wide range of embedded systems in our environment, which motivates the need for a reusable, flexible and manageable Wireless Sensor Network or WSN infrastructure. However, to simplify the system operation and maintenance as well as to reduce costs, WSNs...
Multi-tenancy helps service providers to save costs, improve resource utilization, and reduce service customization and maintenance time by sharing of resources and services. On the other hand, supporting multi-tenancy adds more complexity to the shared application's required capabilities. Security is a key requirement that must be addressed when engineering new SaaS applications or when re-engineering...
As Cloud Computing has become more and morepopular, various Cloud Computing architectures or infrastructurehave been defined, given their specific circumstances forthe applications. However, to effectively achieve the potentialof cloud computing, there is need for the definition of systemarchitecture of the software systems involved in the deliveryof cloud computing, so that it can be used as a reference...
This paper proposes a service-oriented reconfigurable co-processing architecture. The novelty of the architecture is to apply service-oriented concepts to system on chip (SoC) design paradigms and utilizes each processor and IP core as a function unit. Regarded as abstract instructions, tasks can be scheduled to IP core for parallel execution automatically. A uniform IP reconfiguration interface is...
Service Oriented Architecture (SOA) has become the prominent distributed computing paradigm nowadays. One of the technologies that enable the running of SOA is web services. In its nature of similar to peer-to-peer communication, web services involve customer who requests for the service and provider who provides the service. As a result, web services implementation requires a contract agreement so...
In order to obtain an advantageous position in the protean global market, the modern manufacturing enterprises require a flexible and self-adaptive foundation which is capable of dynamically exploiting manufacturing resources and services distributed across the network. In this paper, the cloud manufacturing vision (GetCM) is introduced to provide the on-demand architecture with reliability, flexibility...
Information infrastructure for healthcare is undergoing a transformational shift in the way it is perceived and used by health professionals. This is driven by the need to unify patient records seamlessly, and integrate emerging technologies in the Sensor-Actor Network (SANET) realm that incorporate patient sensory systems such as wireless sensor networks and body-area networks. By harnessing The...
Hierarchical architecture and technical characteristics of Web Services are studied, and combined with develop tendency of the new generation electronic business, the logical structure of dynamic electronic business based on Web Services is put forward, it has the inherent dynamic characteristics, and can help to realize dynamic application integration. On this basis, the seven-layer architecture...
Scripting Languages are often used in order to assist the user in repetitious tasks or when smaller program logics shall be expressed. Normally a scripting language is easier to learn than a programming language so that a wide range of professional developers and end users can use the language for its specific tasks. This paper introduces a specific, small scripting language supporting the deployment...
Service Oriented Architecture (SOA) refers to an architectural paradigm that describes how organizations, people and systems provide and use services to achieve their goals. Moreover, with the evolution of SOA, the focus in software development has shifted from applications to reusable services. Besides, reuse in SOA has more focused on service composition rather than reuse of existing implementations...
In adoption process of Service Oriented Architecture (SOA), the legacy system of a company can not be neglected. The reason is that legacy system runs important role of the business process within the company that has significant business value. However not all migration process of a legacy system to SOA has been successful. Highlighting the right factors to reach legacy system migration success in...
The paper introduces a novel architecture for industrial automation which addresses both the optimization of manufacturing processes and the ability to react to changes in the market demand. The architecture consists of three main components: a mixed-integer-programming level, a two-layered web service level, and an OPC UA server. The web service layer acts as backbone of the architecture and assures...
