LAB 3 WAN Implementation

1. Objective

The objective of designing this lab is to show the WAN implementation. X!

compan" branches are in #lasgow and $anchester while head office is in %ondon& all

the servers r'nning in head office. The goal is to show networ( performance is

affected b" bac(gro'nd traffic. There are two scenarios in the project.

). To show networ( performance witho't bac(gro'nd traffic.

2. Wide Area Network

) Networ( Overview

of interconnected switching nodes. 1nternal nodes ro'ted the transmission from an"

one device to its exact destination. 1nternal nodes are not concerned with the content

of the data. Their act'al f'nctionalit" is to offer a switching facilit" that will shift the

data from one to another node 'ntil the" reach their destination.
