INTRODUCTION:

Topology provides different configurations that are used to create a network. Topologies can be physical or logical. Physical Topology means the physical design of a network including the devices, location and cable installation. Logical Topology refers to the fact that how data actually transfers in a network as opposed to its design. Networks have become a vital part of today’s world. The idea of connecting several computers together has not changed over the years. However, the way in which these computers are connected has changed. The pattern in which computers or devices in a network are connected is called network topology.

 

OBJECTIVES:

  1. To identify and define network topology.
  2. To explain the different types of network topologies used in computer networks.
  3. To identify and explain the different devices used in computer networks.
  4. To differentiate between the devices used in network.

 

Problem Statement (including Literature Review):

 PROBLEM STATEMENT:

There are some problems which are come in a network:

 (1)Share the files and information to client.

(2)Switch does not get a link light.

(3)Clients do not access the files, documents and applications.

 

LITERATURE REVIEW:

Networks have become a vital part of today’s world. The idea of connecting several computers together has not changed over the years. However, the way in which these computers are connected has changed. The pattern in which computers or devices in a network are connected is called network topology A network topology is the pattern in which computers, printers, and other devices are connected in a network. It describes the different layout of wires, devices, and routing paths. There are two types of network topologies, namely physical topology and logical topology.

In the project, the network is created by using the network topology and networking devices in the home, college and office. Network allows the computers to communicate with each other and share resources which include information, software and peripheral devices such as printers, scanners.

Server is a computer system that is shared by several users in a network.  A network consists of more than one computer, each performing a particular task.  A network topology is the pattern in which computers, printers, and other devices are connected in a network. Topology provides different configurations that are used to create a network. A network is a group of devices connected by communication paths to exchange information and share resources.  By the using of network topology, networking devices and transmission media we create a network. The network is used to access the information and files from the server all clients are used to access it. If we want to share the data to the all clients it is possible by the server. In the other words the network is very use full in the world. Transmission media is way to send the data from the one end to other end. In the network, there is use networking devices to create the network. As there is use network operation system is installed in the server to operate the clients and give the facility to the clients to access the data and the information in the network agent for transmission of data in the network.

METHODLOGY TO BE USED:

In this project, there is using the Networking devices, Network topologies, Transmission media and Network operating system. To create a network, the topology provides different configurations that are used to create a network. Computer network can be wired or wireless. Networks can be categorized as pre the geographical area to be covered by the network. Local area networks (LANs) are most commonly used by the organizations need to connect multiple LANs together to extend networks. The networking devices also called as internetworking devices act as an intermediate agent for transmission of data in Hubs, and Switches. Networking involves connection of computers, workstations and peripheral devices. Networking hardware involves all the peripheral devices, interface cards, and other such as cables and equipments wires that are used to establish a network connection.

In the project, the following are used to create the network:

  1. Computer Networks
  2. Transmission Media
  3. Network Topologies
  4. Networking Devices
  5. Network Servers and Clients
  6. Network Operating System

Two Monitoring Techniques are discussed in the following sections: Router Based and Non-Router Based. Monitoring functionalities that are built-into the routers themselves and do not require additional installation of hardware or software are referred to as Router Based techniques. Non-Router based techniques require additional hardware and software to be installed and provide greater flexibility. Both techniques are further discussed in the following paragraphs Router Based Monitoring Techniques: Router Based Monitoring Techniques are hard-coded into the routers and therefore offer little flexibility. Simple Network Monitoring Protocol (SNMP) RFC 1157: SNMP is an application layer protocol that is part of the TCPIP protocol suite. It allows Administrators to manage network performance, find and solve network problems, and plan for network growth. Remote Monitoring (RMON) RFC 1757: RMON enables various network monitors and console systems to exchange network-monitoring data. Non-Router Based Techniques: Although non-router based techniques are still limited in there abilities they do offer more flexibility than the router based techniques. These techniques are classified as either active or passive. Active Monitoring: Active monitoring transmits probes into the network to collect measurements between at least two endpoints in the network.  Active measurement systems deal with metrics such as: • Availability • Routes • Packet Delay • Packet Reordering • Packet Loss • Packet Inter-arrival Jitter • Bandwidth Measurements (Capacity, Achievable Throughputs). Also unlike active monitoring, passive monitoring collects information about only one point in the network that is being measured rather than between two endpoints as active monitoring measures. Two newly introduced combinational monitoring techniques are described below. Watching Resources from the Edge of the Network (WREN) and Self-Configuring Network Monitor (SCNM).
