Study on an Information System Integration Scheme of Enterprises Based on RFID Technology with SOA

Radio frequency identification(RFID) is high technology, which can rapidly and real-timely acquisition information and accurately deal with information. And it has broad application prospects in retail, logistics, transport and other fields. Service oriented architecture(SOA) is a service-oriented architecture, which is used to design and realize the loose coupling software. For the existing shortcomings of current enterprise information system integration, the RFID technology and SOA are introduced into system integration in order to propose a new enterprise information system integration scheme in this paper. In the proposed system integration scheme, the middleware uses the business documents as the carrier of data exchange among other enterprise application systems, and the data stream technology is used to filter and package RFID data. The rule parsing technology is used to control the business processes. The SOA is used to realize the loose coupling and integration of RFID data event and application system, and deal with the configuration of the components. At the same time, .NET Remoting technology is used to realize the distribution architecture of middleware in order to ensure the deployment flexibility of middleware. The applied cases of a demonstrative application system, blood management and traceability system are used to illustrate its feasibility and effectiveness of the proposed integration scheme. The enterprise information system integration scheme provides an effective solution for system integration between different enterprises or internal enterprises. It can solve the compatibility between different application systems, and takes on the higher service efficiency, less CPU average occupation and better average response time. This study provides a stable and effective solution for information sharing between enterprises, improves the work efficiency and reduces the whole work management capital, and continuously improves the informatization level of the enterprises.

Performance Comparison of ICE, HORB, CORBA and Dot NET Remoting Middleware Technologies

Distributed computing systems are designed to solve computationally intensive problems with the help of convergence of computing resources scattered across the network. Distributed computing object middleware technologies have bring revolutionary concepts in the world of distributed computing and also made the building of distributed computing applications more efficient and nearer to real world. But the selection of most efficient distributed computing object middleware technology on the basis of different performance metrics is an important research issue. In this paper we are presenting the performance evaluation and comparison of distributed computing object middleware technologies which include Common Object Request Broker Architecture (CORBA), Internet Communication Engine (ICE), HORB, and TCP based Dot NET Remoting. Because these distributed computing object middleware technologies have not been evaluated and compared collectively on the basis of performance metrics which include overhead generation and round trip latency. The results that we have gathered showed that ICE is showing better performance in terms of overhead generation. And HORB has showed reduced round trip latency as compared to other middleware’s.

A high‐performance and well‐manageable distributed measurement laboratory with an object‐oriented approach

AbstractThe distributed measurement laboratory (DML) can provide users with the capability of performing and practicing their experiments in a transparent manner on remote instruments located in different geographic areas and connected with a wide area network. In this article, we propose a high‐performance and well‐manageable DML, named HPWM, which is characterized by three main novel features: (1) using .NET Remoting to provide better network performance and having scalable and extendable architecture; (2) using Asynchronous JavaScript and XML (AJAX) to provide an efficient and lightweight Graphic User Interface (GUI) without browser plug‐ins; and (3) offering adequate management functionalities to well manage users and instruments and establishing their relationships. The software structure used for developing HPWM is also described. Finally, HPWM has been tested in the academic and industrial education and has shown its correctness and effectiveness. © 2009 Wiley Periodicals, Inc.

A Hybrid Architecture for Implementing Efficient Geospatial Web Services: Integrating .Net Remoting and Web Services Technologies

Open GIS Consortium (OGC) Geospatial Web services have been introduced to overcome spatial non-interoperability problem associated with most geospatial processing systems. Although OGC geospatial Web services provide interoperability among heterogeneous geospatial processing systems, in some cases they can not provide required performance and efficiency. This paper proposes a hybrid architecture which can efficiently provide interoperability and high performance for transferring geospatial data. It is suggested that making use of Web services technologies for implementing OGC geospatial Web services would significantly facilitate sharing geospatial data in heterogeneous environments like Web. In addition, making use of a proprietary and platform-dependant technologies can provide best performance and efficiency in homogeneous environments like an internal network. In this context, design and development of an OGC geospatial Web service using hybrid architecture of Web services Technologies and .NET Remoting technology (as proprietary and .NET specific technology) is described. Based on our evaluations and practical tests, the hybrid architecture proved to be an efficient solution for development of geospatial Web services.

A Secure Approach to Distributed Internet-Enabled Metrology

This paper aims to explore ways of securely operating electrical instruments via the Internet. A system is presented, which allows a person connected to a local area network (LAN) to operate multiple electrical instruments located at other LANs via a public Web server on the Internet, regardless of firewalls, proxy servers, or source network address translators that separate them. A full system test has been performed, and data from the test are later presented. The solution is based on Microsoft .NET Remoting, which is part of the Microsoft .NET Framework. A viable application is Internet-enabled calibration, and possible users are national measurement institutes and calibration laboratories. The solution is general and does not depend on the underlying network connections involved as long as hypertext transfer protocol over secure sockets layer is supported.

Switching supports for stateful object remoting on network processors

Distributed object-oriented environments have become important platforms for parallel and distributed service frameworks. Among distributed object-oriented software, .NET Remoting provides a language layer of abstractions for performing parallel and distributed computing in .NET environments. In this paper, we present our methodologies in supporting .NET Remoting over meta-clustered environments. We take the advantage of the programmability of network processors to develop the content-based switch for distributing workloads generated from remote invocations in .NET. Our scheduling mechanisms include stateful supports for .NET Remoting services. In addition, we also propose scheduling policy to incorporate work-flow models as the models are now incorporated in many of tools of grid architectures. The result of our experiment shows that the improvement of EFT is from 5% to 21% when compared to ETT and is from 8% to 34% when compared to RR while the stateful task ratio is 50%. Our schemes are effective in supporting the switching of .NET Remoting computations over meta-cluster environments.

FORMI: Integrating Adaptive Fragmented Objects into Java RMI

Distributed object-oriented applications are commonly implemented atop middleware platforms such as CORBA, .NET Remoting, and Java remote method invocation (RMI). These platforms provide a simple mechanism to invoke methods of remote objects. Increasingly more applications are demanding nonfunctional properties such as fault tolerance, high availability, and adaptivity, which require extensions to distributed objects' basic interaction model. A fragmented-object model, such as the one Marc Shapiro proposed, can provide the required flexibility. It's far more generic and flexible than the traditional client-server approach. A fragmented object is a truly distributed object; it consists of multiple fragments located on multiple nodes. Such a model allows arbitrary partitioning of state and functionality on these fragments, and arbitrary internal interaction between fragments of a single object. We have investigated integrating a fragmented-object model into CORBA (AspectIX), which requires internal modifications to the CORBA object request broker. Our approach for transparently integrating fault-tolerant objects into .NET Remoting is also useful for seamlessly integrating fragmented objects. Our FORMI architecture integrates fragmented objects into Java RMI without requiring internal modifications to the RMI runtime

A Multithreaded Distributed Telerobotic Framework

A reliable real-time client-server telerobotic system that uses a distributed component framework to promote software reusability, ease of extensibility, debugging, and data encapsulation is proposed. .NET remoting is used for automatic handling of the network resources and data transfer while isolating the components from network protocol issues. A client-server transfer of live stereo video provides the operator three-dimensional (3-D) views of the slave scene with augmented reality (AR) framework and services. Overall distributed framework and design independence improves the portability and modularity of the proposed telerobotic system. A multithreaded execution is proposed for streaming of force, command, and for the transfer of live stereo video data. The proposed framework provides a useful integrated software and hardware environment to enhance man-machine interactions using stereo visualization and AR in real-time telerobotic systems

Matching search in fractal video compression and its parallel implementation in distributed computing environments

Fractal video compression is a relatively new video compression method. Its attraction is due to the high compression ratio and the simple decompression algorithm. But its computational complexity is high and as a result parallel algorithms on high performance machines become one way out. In this study we partition the matching search, which occupies the majority of the work in a fractal video compression process, into small tasks and implement them in two distributed computing environments, one using DCOM and the other using .NET Remoting technology, based on a local area network consists of loosely coupled PCs. Experimental results show that the parallel algorithm is able to achieve a high speedup in these distributed environments.

A Valuable Resource of Programmers Using .NET Technology

For applications to be deployed efficiently, the programmer or developer must have solid distributed systems knowledge, including knowledge of the system architecture and network configurations. Distributed .NET Programming in VB .NET by Tom Barnaby focuses on the new development platform .NET. Barnaby describes technologies you can use to develop efficient distributed applications with .NET, including such technologies as .NET Remoting, Web services, serialization, COM+, and MSMQ.

Concurrent object-oriented programming on .NET

The SCOOP model (Simple concurrent object-oriented programming) offers a comprehensive approach to building high-quality concurrent and distributed systems. The model takes advantage of the inherent concurrency implicit in object-oriented programming to provide programmers with a simple extension enabling them to produce concurrent applications with little more effort than sequential ones. In the paper, the authors discuss the basic concepts of the model, such as processors and separate objects. They also present SCOOPLI, a library implementation of SCOOP for the .NET platform. They show how SCOOP concepts are mapped to .NET constructs, and discuss distributed programming with SCOOPLI, with a focus on .NET Remoting capabilities. Several programming examples illustrate the discussion.
