Network Requirement Analysis And Plan Essay

Question:

Discuss about the Network Requirement Analysis and Plan.

Answer:

Introduction

The fundamentals of network design for the University Campus are discussed in this section. To design a network, its basic concepts such as the network topology also important to be considered and its selection is an important criterion. The geometric representation of network topology is to build relationship among all the links connecting the device nodes (Chapman Cooper & Zwicky, 2000). Network topology represents the physical topology and represents the way in which a network is physically connected. It is logical topology that defines flow of data through the network.

Design types determine the type of Network for the Campus is interested to adopt in order to meet their work system requirements. There are different types of designs available for the company to adopt into their system. The various configurations used in the network set up is LAN, WAN, MAN and CAN. The specific requirement depends upon how much big the area need to get covered along with their complexity. In the small business network setting the need of high frequency Wi-Fi connections demand are high in demand (Chen, Iyer & Whisnant, 2002).

The plan is to analyse and address the star up issues with the University. It is related to their network design, inter networking and implementation process. Since the University is going to have highly distributed, heterogeneous and globalised set of branches across the area hence a comprehensive system of network is designed to maintain their connectivity without any interruption. The network topology is chosen initially and designed as per their requirements.

Network is designed in order to provide 100% availability with time. Efforts are made to maintain the network availability in wide adverse situations of link failure, equipment failure and overload conditions. Network designed to support tremendous traffic loads with the time. Design is carried out with consistent application response time. Protection is provided against unexpected security incidents. The important necessity to build the network includes proper network topology, router, wireless adaptor through which all their systems are internally connected.

The best solution to network design is to ensure that they must meet the basic requirements. In this mode of network design an inter connection of network design procedure has been adopted. This has three components in its network layer namely core layer, distributed layer and Access layer (Ali & Alabady , 2007).

Network Device

  1. Network Interface Card (NIC) or LAN(Local Area Network) Card
  2. Media - Wired or Wireless
  3. Networking devices - Hubs, Switches, Routers etc.
  4. Computers like Laptop or Desktop.

Operating systems like Windows, Linux and Mcintosh and so on.

NIC

NETGEAR

10.10.10.1

RTL8111C(P)

Computers of various types connect to networks via several types of wired and wireless interfaces, the most common being Ethernet and Wi-Fi Alabady, 2008). These interfaces may be integrated into the motherboard, or they may come in the form of an add-on card that connects to the computer via PCI/PCIe or USB.

Hub

Intel(R) Corporation

1.0.5.235

HID

It acts as a central point of communication among e media devices.

3

Switch

Dell Inc

DEMOSERIAL

Devices essentially serve as hubs for the network. Multiple computers link to a router or switch, which itself may be connected to other switches.

4

Router

Cisco

Cisco router_30

Cisco - 1841

These devices setup their own sub network. Only one per one device is permitted.

  • A design table specifying IP network
  • IP address specifying Network Topology diagram
  • Management Software access to every computer from each of the location using a fixed IP address.
  • Network configuration (ACL configuration and Router interface with explanation)

The cables are often used in the networking set up. Although now a days the cable requirements are often, but the use of cable is perhaps required in minimum amount. There are various type of cable such twisted pair cable unshielded, twisted pair cable shielded, co axial cable, fibre optic cable, and wireless LANs.

The most important server operating system used is that UNIX –like operating system. They are open source system. They have the features of ability to fast recognise and software and hardware updating capacity without re starting the system. They have the capacity of flexibility an transparent data transfer among the devices. They have to store tera bytes of data in daily basis and hence th size of the data sources are enormous. The server has space ranging from 16 GB to 128 GB RAM and are equipped with multi-tera byte HDD storage.

Network Design in Netsim

NetSim 8.0 is an application. This system of software allows to apply the vision of network design within the application. They are performed using the Cisco command line equipment. NetSim is a network simulation and emulation tool. It is mainly used for the purpose of network design. It is done with the basis of network planning and management system. Many technologies are being covered in th design process using NetSim. Thy are wireless sensor networks, wireless land area network system, MANETs, LTE and many more.

Network navigation mode allows viewing the devices tat are closely connected with each other and with whom they are connected sequentially. At the same time they have the feature of displaying the network connectivity in the active mode. By right clicking on the device, we can view the device with the topology in order to access the selected device. The sequential set connectivity using NetSim has been shown in the below representation. The simple way of connection is at first shown and it is then followed by rest of the connectivity for the entire University campus.

This shows how the routers are connected and forming sub networks.

This shows how all the other networks are being connected for the access control from the management system.

The network connection design along with the simulation result is shown.

During the installation of the operating system the network software installation takes place. A certain IP configuration parameters are used in the appropriate files tat are stored. They are stored in such a way that they can be read at the boot time Akyildiz, Melodia & Chowdhury, 2008).

After the completion of building the entire network, it is required to make sure for the testing of the equipment and the performance monitoring of the entire network for the specific range of duration. Before starting the complete set up, it is required to test the entire network performance. To avoid the situation of sudden system failurerity, it is utmost require to keep a regular monitoring system. The monitoring system is required to enable all of this redundancy (Akin, 2002).

Conclusion

World class University in today’s scenario is impossible without emails, online banking and all other important services that are linked by the internet. The services computer network plays an important role to access the information necessary to maintain the connecting operation. For interconnectivity of components within the campus a network topology adapts to the physical and set up and to maintain the interconnection between arrangement of computers, cables and other component. It is important in a data communication network since the information travels through packet form from one device and sending it through the network to another device on a different network.
