Networking Goals
 The company XYZ requires a network infrastructure to setup LAN
networks for its branches at Sydney, Melbourne and Adelaide.
 The overall network of the company must ensure inter departmental
data transfer within each of these LAN networks.
 The LAN networks of Sydney, Melbourne and Adelaide require 63, 53
and 43 IP addresses of subnets A, B and C respectively.
 The router of the Sydney network connects routers of Melbourne and
Adelaide with two IP addresses of subnet D.
 Every host must also be able to access the Internet.
 Every LAN network should support wireless network connectivity.

Networking Architecture and Purpose
 The network design follows the
three-layered hierarchical
network architecture.
 Network designs based on this
model is to use minimum
networking devices.
 Such designs also ensure that
the network is easily scalable
and expandable.

Network Design
 The network proposed follows a
top down approach.
 The networking devices are
positioned across three layers –
core, distribution and access.
 Core contains the routers,
distribution comprises of L3
switches and access consists of
L2 switches.
 Wireless network connectivity is
ensured by wireless access
points.
