In this report I will be talking about the practical I did, I will be talking about the purposes of each device and their role within my network. I will also be talking about my chosen IP addressing for my network and why it is suitable for the network. I will be also talking about the choice of cables I used to connect the devices together.
1.0 – The purpose of each device
1.1 – Server
Server’s provide functionality for programs or devices, also called clients. This is called a client-server model. Servers also provide various functionalities, such as sharing data or resources among multiple the clients on the server. A server can serve multiple clients, as well as the single client being able to use multiple servers. The typical server various from database servers, file servers, mail servers, print servers, web servers, game servers, and application servers, all vastly used throughout the world.
1.2 – Router
Routers are networking devices that can forward the data packets transmitted between the computer networks. Routers can perform traffic directing functions, these data packets are forwarded through one router to another until the data has reached its location.
Routers connect to two or more data lines typically are from different networks. When the data packets are being processed within one of the lines, the router automatically reads the network address information. It then checks the set-up routing table or routing policy to determine the packet’s destination. After, the packet is directed to the next network.
1.3 – Switch
Network switches or hubs are computer networking devices that allow connections to other devices possible, together within a computer network by using the packet switching to receive, process, that can forward data to the destination device.
The network switch uses assigned hardware addresses that can process and forward data.
1.4 – PC
2.0 – Cabling used
Crossover cables can connect two devices of the same type together, for example, DTE-DTE or DCE-DCE these are usually connected asymmetrically (DTE-DCE), by a modified cable called a crosslink.
The most common cross-over cable used in modern networking is the Ethernet crossover cable. This type of crossover cable is used to connect two computing devices together directly. For example, two computers (via their network interface cards) or two switches to each other.
Why its chosen
2.1 – Copper straight-through
The straight-through cable is a twisted pair of cable, which is common in local area networks to allow connection of a computer to the network hub/router. The cable is also called a patch cable and is used as an alternative to wireless connections where computers access the router through a wireless signal.
The straight-through cable is used to connect the different types of devices together. Below is a list of when this cable is used.
· Connect a computer to a switch/hub’s normal port.
· Connect a computer to a cable/DSL modem’s LAN port.
· Connect a router’s WAN port to a cable/DSL modem’s LAN port.
· Connect a router’s LAN port to a switch/hub’s uplink port. (normally used for expanding network)
· Connect 2 switches/hubs with one of the switch/hub using an uplink port and the other one using the normal port.
Why its chosen
3.0 – Choice of IP addressing scheme
In the lab, the chosen IP address scheme was the 172.20.xxx.xxx with the subnet of /26 and /30 subnet mask. The /30 subnet mask was chosen for the router and server, the /30 subnet is perfect for 2 devices as this subnet only has 4 addresses, 2 which are usable. The /26 subnet was used as the network can have up to 62 hosts, which will be best for a small business.
3.1 – IP Addresses
· Server IP Addressing – 172.20.5.66/30
· Router IP Addressing- 172.20.5.65/30 interface g0/0 ~ 172.20.5.1/26 interface g0/1
· Switch (VLAN1) IP Addressing – 172.20.5.2/26
· PC IP Addressing – 172.20.5.3/26
· 255.255.255.192 /26 – 64 addresses / 62 Hosts
· 255.255.255.252 /30 – 4 addresses / 2 Hosts
