Remote Process Control Over the Internet
Session 1520 Remote Process Control over the Internet Mark Smith Purdue University North Central Abstract This paper presents remote process control over the Internet using remote-control computing software. Remote-control computing software allows you to connect to remote computers from your computer and control those systems. You can monitor and control attached system processes, provide problem solving assistance, upload and download files, and even change system parameters. This paper describes what remote-control computing is, who the major players in the industry are, and how it can be used to monitor and control remote processes. A case study of remote-control computing software in operation is also presented, describing how one off-the-shelf package was setup to monitor and control a plant floor production system. Introduction Networking technologies, and especially the Internet, have become a major component of application systems. As we teach the design and implementation of process control systems in the Engineering curriculum, we must recognize that these systems will require capabilities for control and support from remote locations. For example, the need for remote control may be driven by the high cost of a particular process. The Oak Ridge National Laboratory uses remote process control at its High Temperature Materials Laboratory to allow researches from across the country to use a million-dollar electron microscope1. Even when control of the process is not required across the country, there are times when it is helpful (or even critical) to monitor another node on a LAN. For example, Conquergood describes in his research the ability to monitor and control potentially high voltages from one location by gathering voltage information from PCs doing data acquisition from various plant processes2. -
"IT Tools in the Virtualization of the Software Implementation And
INFORMATYKA EKONOMICZNA BUSINESS INFORMATICS 1(23) · 2012 ISSN 1507-3858 Iwona Chomiak-Orsa, Wiesława Gryncewicz, Maja Leszczyńska Wrocław University of Economics e-mail: [email protected] IT TOOLS IN THE VIRTUALIZATION OF THE SOFTWARE IMPLEMENTATION AND MAINTENANCE PROCESS Abstract: By implementing modern technological solutions, companies re-organize their activities. The remote software implementation process and then the remote maintenance mean for companies a new approach to gaining competitive advantage. In practice, it gives the opportunity to reduce costs and hence the prices of services. These two processes beco- me also independent of the geographical location of the client and the contractor, which can significantly reduce response time to reported problems and help ensure the higher quality of service. The IT support is needed to efficiently and quickly virtualize software imple- mentation and maintenance process, so the aim of this paper is to present and characterize such IT tools. Key words: virtualization, implementation, maintenance process. 1. Introduction Nowadays we are witnessing that the world has entered the information society era. The basic resources have become information and knowledge obtained from their processing. Digital products and services dominate the market. The availability of the transmission networks and sources of information has become more common and easier, while significantly reducing the costs of this access. Extensive use of IT tools in the economy, government, education and culture as well as in organization and management, has created new opportunities for all market participants and their environment [Steinmueller 2005, pp. 133–152]. By implementing modern technological solutions, companies re-organize their activities not only in the B&C context, but also in relation to other companies through the value-creation chain [Szpringer 2008, pp. -

Storage of Network Monitoring and Measurement Data
Storage of Network Monitoring and Measurement Data A report submitted in partial fulfillment of the requirements for the degree of Bachelor of Computing and Mathematical Sciences at The University of Waikato by Nathan Overall c 2012 Nathan Overall Abstract Despite the limitations of current network monitoring tools, there has been little investigation into providing a viable alternative. Network operators need high resolution data over long time periods to make informed decisions about their networks. Current solutions discard data or do not provide the data in a practical format. This report addresses this problem and explores the development of a new solution to address these problems. Acknowledgements I would like to show my appreciation to the following persons who have made this project possible. Members of the WAND Network group for their continued support during the project, including my supervisor Richard Nelson. I would also like to give a special mention to Shane Alcock and Brendon Jones for their ongoing assistance to the project while they developed the WAND Network Event Monitor. DR. Scott Raynel for his support and advice throughout the project. The WAND network group and Lightwire LTD for providing the resources necessary to conduct the project.

WWW URL: http://www.usenix.org MRTG – The Multi Router Traffic Grapher Tobias Oetiker – Swiss Federal Institute of Technology, Zurich ABSTRACT This paper describes the history and operation of the current version of MRTG as well as the Round Robin Database Tool. The Round Robin Database Tool is a program which logs and visualizes numerical data in a efficient manner. The RRD Tool is a key component of the next major release of the Multi Router Traffic Grapher (MRTG). It is already fully implemented and working. Because of the massive performance gain possible with RRD Tool some sites have already started to use RRD Tool in production. Motivation MRTG logged its data to an ASCII file, rewriting it every five minutes, constantly consolidating it, so In Summer 1994, the De Montfort University in that the logfile would not grow over time. The logfile Leicester, UK, had one 64 kBit Internet link for more did only store slightly more data than was needed to than 1000 networked computers. As it was not possi- draw the graphs on the web page. The graphs were ble to get a faster Internet link for another year, it was converted to GIF format by piping a graph in PNM desirable to at least provide the users on campus with format to the pnmtogif tool from the PBM pack- current and detailed information about the status of the age. -
