Abstract
The applicability of network-based computing depends on the availability of the underlying network bandwidth. However, network resources are shared and the available network bandwidth varies with time.
There is no satisfactory solution available for network performance predictions. In this research, we propose, design, and implement the NBP (Network Bandwidth
Predictor) for rapid network performance prediction.
NBP is a new system that employs a neural network based approach for network bandwidth forecasting.
This system is designed to integrate with most advanced technologies. It employs the NWS (Network
Weather Service) monitoring subsystem to measure the network traffic, and provides an improved, more accurate performance prediction than that of NWS, especially with applications with a network usage pattern. The NBP system has been tested on real time data collected by NWS monitoring subsystem and on trace files. Experimental results confirm that NBP has an improved prediction.
Index Terms— Performance prediction, Network bandwidth, Artificial Neural Network, Distributed computing 1. Introduction
Performance monitoring and forecasting is an active area of research. In the growing world of networking, more emphasis is being placed on speed, connectivity, and reliability. When network problems occur, they often result in catastrophic breakdowns. Due to the heterogeneity and the constantly varying nature of the network traffic, there are only a few works available to provide prediction of network performance in terms of

available bandwidth and latency in a heterogeneous environment, such as Grid computing.
Network Weather Service (NWS) [1, 2] is a wellused network performance measurement and
prediction

    1. Your OS will use the hard drive as a "swap file" or virtual memory, if your PC runs out of RAM while you are working away. Using your hard drive as memory causes a serious performance hit, as hard drives are slower than RAM. You must have enough memory, adding more does not help if you are not doing anything that needs more memory. Today, a modern PC and a modern OS need about 4 gigs to achieve this for most standard users. You want enough RAM so the OS doesn't start using the hard drive as memory.…

    In this paper I will be going over a network design proposal for a building on the UMUC campus in Adelphi, Maryland. I would plan to run a fiber optic network to ensure the fastest speeds possible and fiber optics are notorious for not having any signal loss compared to a Cat5e. Using a star topology throughout the building with the servers in each classroom connected to the server room on the respective floor. Equipment used to build the network will consist of servers, routers, hubs and computers. There will be a physical firewall installed on each server and an IDS (Snort) for the network as well as AVG firewall and virus scanner.…

    UMUC’s new building in Adelphi, MD will have to provide networking connectivity to students, professors, and staff. In order to begin the process of planning the new network, we will begin by planning the network IP addressing scheme. It is very important that the network IP addressing scheme be clearly defined in order for IT administrators to locate computers promptly. Also, in order to make it easier for the administrators, DHCP (Dynamic Host Configuration Protocol) will be used to assign IP addresses. The organization of the subnet layout will assist the IT administrators as well as making effective use of IP addresses.…

    Bandwidth

    Computers store all information as binary numbers. The binary number system uses two binary digits, 0 and 1, which are called bits. The amount of data that a computer network can transfer in a certain amount of time is called the bandwidth of the network and is measured in kilobits per second (kbps) or megabits per second (mbps). A kilobit is 1 thousand bits; a megabit is 1 million bits. A dial-up telephone modem can transfer data at rates up to 56 kbps; DSL and cable modem connections are much faster and can transfer at several mbps. The Internet connections used by businesses often operate at 155 mbps, and connections between routers in the heart of the Internet may operate at rates from 2,488 to 9,953 mbps (9.953 gigabits per second) The terms wideband or broadband are used to characterize networks with high capacity and to distinguish them from narrowband networks, which have low capacity. Research on dividing information into packets and switching them from computer to computer began in the 1960s. The U.S. Department of Defense Advanced Research Projects Agency (ARPA) funded a research project that created a packet switching network known as the ARPANET. ARPA also funded research projects that produced two satellite networks. In the 1970s ARPA was faced with a dilemma: Each of its networks had advantages for some situations, but each network was incompatible with the others. ARPA focused research on ways that networks could be interconnected, and the Internet was envisioned and created to be an interconnection of networks that use TCP/IP protocols. In the early 1980s a group of academic computer scientists formed the Computer Science NETwork, which used TCP/IP protocols. Other government agencies extended the role of TCP/IP by applying it to their networks: The Department of Energy's Magnetic Fusion Energy Network (MFENet), the High Energy Physics NETwork (HEPNET), and the National Science Foundation NETwork (NSFNET).…

    Networking Gadgets, Inc. requirements are secured centralized access network for 18 people that is easy to manage and back up. They need server-based network because peer-to-peer network model has no centralized authority or control over resources. On the other hand, server-based network provides centralized control over network resources and will have secure access to project files and will fulfill company’s need for centralized management and back up requirement. So, all of these factors are the key reasons for using server-based network.…

    Cryptography is derived from the Greek words kryptos meaning “hidden” and graphien, meaning “to write/study”. The process of making and using codes to secure the transmission of information is called cryptography. Before modern era cryptography was synonymous to encryption but today cryptography is heavily based on mathematical theory and computer science practice. Cryptography today deals with the ways to transfer information in such a manner that no one beside the recipients can read what was actually sent and also more advanced crypto techniques deal with ensuring that the information being transferred has not been compromised in the transit. Cryptanalysis is the process of obtaining the original message (Plaintext) from an encrypted message (ciphertetext) without knowing the algorithms and keys used in encryption. Crypto is a tool that can be used in both good and bad ways. Some of the good crypto uses are:…
