Project Overview

Overview
IT 2 is a laboratory room consisting of many PCs, with an appropriate network connection the room will be much more efficient to use. In this network we will be using server based network environments that will manage and facilitate the whole network. This network will implement the star topology for easier expansion of workstations and for easier troubleshooting in case an error occurs.



Objectives

1. To create a network design for the room IT2 that will provide students and instructors with a network connection for easier file sharing for each computer in the class room.
2. To help Instructors with easier and well organized way of checking files due to the help of the network connection

Hardware Requirements

1 Router
24 workstations
2 Hubs
Category 5 Unshielded Twisted Pair Cable
RJ45

Network Installation

Our group discussed about the topologies that we will use, we have come to the decision to use the star topology to implement in the room IT2.





Advantages of a Star Topology

• Easy to install and wire.
• No disruptions to the network then connecting or removing devices.
• Easy to detect faults and to remove parts.

Disadvantage of a Star Topology

• Requires more cable length than a linear topology.
• If the hub or concentrator fails, nodes attached are disabled.
• More expensive than linear bus topologies because of the cost of the concentrators

The protocols used with star configurations are usually Ethernet.

Switch

D-Link DES-1016 16 Port Switch

Superior Performance, Exceptional Value, Auto Sensing 10/100 ports

Price: P 2,080 x 2 = 4,160

Product Description

The DES-1016D is an unmanaged 10/100Mbps switch designed to enhance workgroup performance while providing a high level of flexibility. Powerful yet easy to use, this device allows users to simply plug any port to either a 10Mbps or 100

Mbps network to multiply bandwidths, boost response time and satisfy heavy load demands.

16 Auto-sensing 10/100Mbps Ports
The switch comes with 16 10/100Mbps ports, allowing a small workgroup to flexibly integrate to Ethernet and Fast Ethernet. These intelligent ports detect the network speed and auto-negotiate between 100BASE-TX and 10BASE-T, as well as between full and half-duplex.

Flow Control for Secure Transmission
All ports support flow control. This function minimizes dropped packets by sending out collision signals when the ports receiving buffer is full.

Auto-negotiation of MDI/MDIX Cross Over
All ports support auto-negotiation of MDI/MDIX cross over. This eliminates the need for cross over cables or uplink ports. Any port can simply plug to a server, a hub or a switch, using the usual straight-through twisted-pair cable.

Plug-and-Play
With 16 plug-and-play ports, the switch is a perfect choice for workgroups to upgrade performance in a client/server environment. The ports can be connected to servers in fullduplex, or hubs in half-duplex.

Direct Connection to Workstations
With low-cost connection per-port, the switch can be set up for direct connection from the PCs. This relieves data bottleneck by giving each workstation a dedicated bandwidth on the network.

Wiring Standards and Procedures

Introduction

The interconnected hardware components, Category 5 UTP cable, rj45, hubs and other elements that construct the network for the room of IT2 are constructed by the LAN network technology that confined these hardware components to travel the data and protocols along distances. The following is a list and concise explanation of the standards and cabling components for the LAN of IT2. During the design and installation of LAN in IT2, there are several things to deliberate regarding on how the design and installation can be structured depending on the hardware components and materials that have multiple choices to build the LAN covering the small physical area of IT2.

Standards

The documented agreements containing technical specifications and precise criteria that how network cable should be installed using the hardware components, LAN and star topology should be performed by the EIA/TIA (Electronics Industries association/ Telecommunications Industries Association) wiring standards. It provides flexible way of representing the acceptable performance of the network. The standards are capable for transmitting protocols and data at a certain speed. Without these standards there would be difficulty to design the network in IT2 because the materials, software, and hardware from different manufactures will not be sure to use. Using these standards the network connection will enhance the capable of being bent of communication and also increase the competent in the use of computers. Using the star if a computer fails, it will not affect the rest of the network and other computers can continue to communicate.

Topology

Star Topology

A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network switch.

Data on a star network passes through the hub or concentrator before continuing to its destination. The hub or concentrator manages and controls all functions of the network. It also acts as a repeater for the data flow. This configuration is common with twisted pair cable; however, it can also be used with coaxial cable or fiber optic cable.

Category of Wires

Category 5 UTP cable

The specification for category 5 cable was defined in ANSI/TIA/EIA-568-A,with clarification in TSB-95. These documents specified performance characteristics and test requirements for frequencies of up to 100 MHz.

Category 5 cable includes four twisted pairs in a single cable jacket. This use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and other pairs (this latter form of interference is called crosstalk). It is most commonly used for 100 Mbit/s networks, such as 100BASE-TX Ethernet, although IEEE 802.3ab defines standards for 1000BASE-T - Gigabit Ethernet over category 5 cable. Cat 5 cable typically has three twists per inch of each twisted pair of 24 gauge copper wires within the cables.

Connector

RJ45 Connector wiring

A Registered jack (RJ) is a standardized physical Network Interface both jack construction and wiring pattern for connecting telecommunications, data equipment , computer networking equipment to a service provided by a local exchange carrier, a long distance carrier, or a data network in the case of the RJ45 connector
