Network Design Report: LAN, WAN, and Network Topology Analysis

This report provides a comprehensive overview of network design, focusing on the implementation of LAN and WAN networks for a head office and its branches. The report begins with an introduction to networking, emphasizing the importance of data and resource sharing. It then delves into the specifics of LAN design, including the use of routers, hubs, and wireless access points, along with considerations for wired and wireless connectivity. The report analyzes network topologies, specifically mentioning bus topology, and discusses the use of internet protocols for network communication. The WAN design section covers the devices used, such as modems, CSU/DSUs, and routers, along with the choice of wireless media for connecting different office locations. The report highlights the suitability of a packet-switched network structure and recommends OSPF as a routing protocol. The report concludes by summarizing the key aspects of the network design, including the use of specific devices and protocols for efficient communication and information transfer. The report also includes a list of references that were used for the assignment.

INTRODUCTION
 Networking is considered as practice of exchanging and transfer of data and
resources between computers, over the different channels in an information
system.
 The connection between devices could be wired or wireless. Information
sharing and transferring is important for organization in effective working and
goal achieving.
 Better communication and data transfer can improve the operation efficiency
of organization.

LAN NETWORKING DESIGN FOR HEAD
OFFICE
 Server
 Router
 Hub
 WAP

Networking Media
 There are two types of networking medias can be used for the LAN network in
organization which are wired or wireless. As per the case study organization
need both type of connection for their head office. For this organization can
use specific devices like router to provide both wired and wireless connection
to workstations.

Network Topologies and Protocols
 Network Topology- Bus Topology
 Network Protocol- Internet Protocol

Internet Access Provider
 Modem is the device that can be used by organization to access internet.
Various routers in the organization can be connected to modem to provide
network access to workstations.

WAN DESIGN FOR ORGANIZATION

Devices that are Used in WAN Network
 Modem
 CSU/DSU
 Access Server
 Router
 Core Router

Type of Media Used for WAN
 In order to maintain communication between offices of company wireless
media is used because the offices of organization are located on different
locations in Australia

Suitable Network Structure
 For the long-distance communication and data transfer Packet switched
structure is most suitable because in circuit type network structure
organization needs point to point connection between companies which is
physical difficult for company.
