Shared Event Model Key Words A commonly used model in collaboration is Shared Collaborative System, Open Office, Shared Event. Display. In this model, some amount of screen image in a format (e.g. bitmap) is sent over the networks between the collaborating computers each time when the image of the 1.

The Remote Desktop Connection of Microsoft Open Office [1] is an open source office suite; it has Windows XP and VNC (Virtual Network Computing) [7] similar functionality as Microsoft Office suite. Because it are using this model. is free downloadable, and every one has an opportunity to It is appropriate in situations especially where the develop and contribute to the resource using a broad screen output is random, like online meeting, discussion, range of programming languages and protocols, it has the sharing data (text, graph, image, etc.,) or impromptu features such as availability, usability, extensibility, presentations using some software. popularity, and versatility. It is people’s common property The disadvantages of Shared Display include: and wisdom. • It consumes big bandwidth of the networks Impress is a presentation application in Open because of the image transferring.

The underlying communication environment to communicate waiting time depends on the amount of image messages between the clients in a session. of a screen that needs to update. The worst The master client lectures and broadcasts its event case is when the image changes abruptly, say, messages to all participating clients. the whole screen. The applications make use of the functions of Open Let’s examine a case of using presentation files in Office/Star Office, and collaborate between the Master collaboration, such as Microsoft PowerPoint (.ppt) or and Participant clients so that they share the same Open Office/Star Office Impress (.sxi) files.

  • Solving Quarto with JXTA and JNGI
    Solving Quarto with JXTA and JNGI Matthew Shepherd University of Texas at Austin Abstract. This paper presents an implementation of a grid-based autonomous quarto player. The implementation uses the JNGI framework which itself is written on top of JXTA. 1 Introduction Quarto is a game reminiscent of tic-tac-toe. It is played with sixteen unique pieces on a four-by-four square board. Each piece is large or small, black or white, solid or hollow and square or round. The game begins with an empty board and all sixteen pieces available. Two players take successive turns with the first player choosing an available piece. That piece is given to the second player who places it on an empty spot on the board. The roles reverse and the process repeats. A player wins by placing the final piece in a row, column or diagonal where all four pieces have at least one attribute in common. For example, the winner might place a piece that completes a row of four black pieces or a column of four round pieces. My goal was to write an implementation of the game and an autonomous program for a human player to compete against. The program performs an exhaustive search of possible moves in order to find the most appropriate one. If the program were to perform the search on the first move of the game, the sixteen available pieces and sixteen empty squares would combine to produce a (16!)^2 search space. Eliminating the moves that take place after a game has already been won reduces that number, but a single processor would still not be sufficient to perform such a task in a reasonable amount of time.

Furthermore, AMD and Intel announcing specifications for integrating the use of virtual machines eases the deployment of a wide IOMMUs (Input/Output Memory Management Units) with range of legacy systems that may subsequently be exposed upcoming architectures.

  • Decentralized Grid Services on P2P Networks: a Case Study
    Decentralized Grid Services on P2P Networks: A Case Study FREDRIK SÖDERSTRÖM Master of Science Thesis Stockholm, Sweden 2005 IMIT/LECS-2005-05 Decentralized Grid Services on P2P Networks: A Case Study FREDRIK SÖDERSTRÖM Exam iner Assoc. Prof. Vladim ir Vlassov (IM IT/KTH) Master of Science Thesis Stockholm, Sweden 2005 IMIT/LECS-2005-05 Abstract Computers have been connected to networks for a long time. Traditional networks usually provide only simple services. To keep up with the ever- increasing demand for computing resources, like processing power and storage, there is a need to leverage more power from existing networks. One way of managing all resources of large networks, and letting multiple organizations share these resources with each other, is called Grid comput- ing. In this thesis, we examine one of the services that is necessary for a Grid, namely resource discovery, a mechanism for finding the available re- sources on a network. Resource discovery services are often designed to rely on some kind of central repository where all resources must be regis- tered. But this approach does not work well in very large networks, be- cause the central repository will become a bottleneck. Resource discovery can also be decentralized, and we suggest that it should be built on peer-to- peer technology to achieve maximum scalability. Using JXTA, a peer-to- peer platform, and the Globus Toolkit for Grid services, we create and evaluate a prototype implementation of a distributed discovery service. Acknowledgments I would like to thank my father, Håkan Söderström, for helping me with a number of bugs and reading drafts of the report.

  • Edge-Based Network Attack Detection Using Apache Pulsar
    Volume 5, Issue 8, August – 2020 International Journal of Innovative Science and Research Technology ISSN No:-2456-2165 Edge Based Network Attack Detection Using Pulsar Sheetal Dash IJISRT20AUG624 www.ijisrt.com 1501 Volume 5, Issue 8, August – 2020 International Journal of Innovative Science and Research Technology ISSN No:-2456-2165 ABSTRACT The edge-based network attacks are increasing largely in size, scale and frequency with the booming internet. The Distributed Denial of Service (DDoS) attacks is one of the most diffused types of attacks in the cyberworld which is a great concern for all organizations today. There were 5.2 billion Google searches in the year 2017 alone. Research shows that there cannot be a better example to show how prevalent internet use is nowadays. What started off as a point to point conversation in 1970s as a mode of communication has expanded to millions and millions of devices communicating with each other via some or the other form of the web. And therefore, this research focuses on the strategic approach that has been taken to defend from the growing cyber threat. In this dissertation, the focus is on defending against these edge-based network attacks and collaborating with other neighboring networks in order to communicate with them to transfer information about potentially malicious hosts. This research has focused on exploring ways of integrating the Software Defined Networking with the pub-sub messaging system in order to show a collaborative approach of defense to these attacks. The attacks from unknown multiple sources have also been analyzed in order to cope with them through this robust solution that has been proposed and implemented in this dissertation.
