PART A: DESIGN THE PROPOSED TOPOLOGYTask 1: Produce a performance analysis documenta.The network topology has one broadcast domain as the router connects to a switch that has connections with all other devices on the network. Within the broadcast domain there are 17 collision domains.All devices are connected to a D-Link DES-1026G 24 port 10/100 (Mbps) unmanaged switches viaCat3 cables. The Cat3 cable has a maximum speed of 10MBps.The first floor requires 37 ports, with 30 for the administration staff. Second floor requires 64 ports, third floor needs 47 ports and level 4 requires 52 ports. Aside from the first floor, the other floors has adequate amount of ports. The first floor will need an additional switch to accommodate for all the devices on that levelThere are switches connecting each floor to the one above and or below it, this creates a single LAN which causes congestion due to the amount of data travelling through these switches to get to the database server. b.To reduce congestion the company could employ logical division on switches. This will increase the LAN bandwidth’s availability and improve the network traffic.
