The current Internet does not enable easy introduction and deployment of new network technologies and services. This paper aims to progress the Future Internet (FI) by introduction of a service composition and execution environment that re-use existing components of access and core networks. This paper presents essential service-centric platforms and software systems that have been developed with...
With the characteristics of open source, excellent index structure and system architecture, Lucene promotes the application of full-text retrieval technology in various industries and fields greatly. In this paper, the system architecture and operational mechanism of Lucene were discussed. Further, according to the requirement of external network information leakage monitoring and querying system,...
For constructing a Pub/Sub middleware to detect and disseminate events in the Internet of Things (IoT), we have to pay close attention to the following requirements: (1) the IoT applications usually care about the events with both spatial and temporal extents, (2) It must address the issues brought by the IoT features, such as autonomy embedded in collaboration among things, dynamics implied by running...
SaaS (Software as a Service) is a kind of application services which is provided via Internet, and customers can order and receive their peculiar types of software application services from the SaaS provider via the Internet according to their actual needs. This paper analysis current development of SaaS, by means of comparing SaaS model with traditional software model, a new engineering method is...
The intelligent interaction is an important supporting technique for achieving the merging of the information space and physical space in the internet of things. For now there isn 't a general architecture of the intelligent interaction in the environment of the internet of things. In this paper, we propose an intelligent interaction architecture based on the context merging in the internet of things...
The integration of sensor networks with service oriented architectures requires explicit representations of sensor information and interfaces. A strong candidate language for modelling sensor information is SensorML. SensorML as opposed to other sensor modelling languages supports a specification of a process model associated with a sensor system. As a way of facilitating interaction with other decision...
Parlay is an efficient and flexible approach that enables telecom operators to efficiently wrap up their network services and capabilities and allows third parties to flexibly access those services for deployment of new applications that drive consumption of network services. This paper describes an Internet-mobile platform for telecom applications based on Parlay X. Our solution aggregates resources...
The concepts and principles of layered design method and collaboratively using of different tools for developing network application system are presented in this paper. The recommended layered architectures are given respectively for the applications based on Client/Server model, Distributed Computing model and Web Database model. The advantages and disadvantages of layered design are also analyzed...
Many efforts are centered around creating large-scale networks of “smart things” found in the physical world (e.g., wireless sensor and actuator networks, embedded devices, tagged objects). Rather than exposing real-world data and functionality through proprietary and tightly-coupled systems, we propose to make them an integral part of the Web. As a result, smart things become easier to build upon...
Software as a Service (SaaS) has gained momentum in the past few years and businesses have been increasingly moving to SaaS model for their IT solutions. SaaS is a newer and transformed model where software is delivered to customers as a service over the web. With the SaaS model, there is a need for service providers to ensure that the services are available and reliable for end users at all times,...
Cloud service providers (CSPs) should institute the necessary security controls, including restricting physical and logical access to hyper visor and other forms of employed virtualization layers. To enact relevant security measures, the core elements communicating with the hyper visor need to be secured. A proposed security model will introduce some of the aspects that need to be secured in the virtual...
In the current environment of accelerating technological change, software development continues to be difficult, unpredictable, expensive, and error-prone. Model Driven Architecture (MDA), sometimes known as Executable UML, offers a possible solution. MDA provides design notations with precisely defined semantics. Using these notations, developers can create a design model that is detailed and complete...
Some technical problems in developing Java Web application software are discussed. With introduction of SH (Struts + Hibernate) middleware, the advantages of SH in J2EE software development are analyzed, and a feasible B/S software architecture is proposed in this paper. The interface coupling between different layers of software architecture reduces the influence on the whole software system caused...
This paper presented a Kahn Process Network (KPN) based service composition environment called CSCE which can establish interactions among computational service nodes. KPN is a model of computation and commonly used for describing a set of cooperative processes that communicate with each other using FIFO buffered channel. KPN has several advantages which make it adequate to model service interactions:...
With the blast of information available on the web and the relevant documents set returned by search engineer can not meet the user's needs, the question answer system research is promoted. In this paper, we introduce the structure of Question Answer system based on SOA, define the structure of the dictionary of Keywords and searching template, the word segmentation algorithm based on the dictionary...
Globalization, financial crisis, requirements of the students from the XXI century and other factors are leading to pressure on universities in terms of ensuring appropriate IT (Information Technology) supports necessary for educational and research/development activities. Using an integrated approach based on SOA (Service-Oriented Architecture), BPM (Business Process Management) and Cloud Computing...
The current Internet is built on a set of protocols, but exhibits problems in supporting applications. The network is optimised for best-effort traffic, but other functional aspects are widely neglected. Applying concepts well-known in software engineering (abstraction, composition, separation of concerns) to design the future Internet architecture is seen as a promising way forward. This paper presents...
Economic model is mainly used to study the quantitative relationship of economic phenomena. In this paper, a didactical system on economic model based on ASP and MATLAB Web Server technology is developed, which is characterized by model learning, student-teacher interaction and model exploration. The system is useful to make the teaching more vivid, and improve the quality of the economic model learning...
The paper introduces a control system design of a new type of coater of sealant, and details the function and principle of the system, and describes the software architecture and protection system of the system. The coater of sealant is one of the most important part in the gearbox assembly line . Besides the functions of automatic glue and detect automatically to give an alarm, it also can communicate...
This paper presents an environment for molecular visualization with multi-projection and collaboration capabilities between geographically dispersed research groups. It was drafted a hardware and software architecture whose purpose is to reduce the negative effects of the delay in communication inherent long-distance networks.
