Executive Summary
Network Design is a platform in which implementation planning is done for computer
network infrastructure. In the network design conceder, all the reliable deliver the
application. In the network design, we have protected the data which is transmitted from it.
Network design can grow for the new application without impacting the services of the
level. For design, the new network design, planning the location for the security of the
devices with critical network resources.

Task -1
Research methods to design network
Methods for network design:
1. Cisco Packet Tracer Method
Cisco packet tracer is a powerful programme to generate the design of the network. Cisco
packet tracer provides the simulation, visualization, and authoring process to find out the
technical concept. It provides the multiple opportunities for instructors to design the
complex networking design. It gives the fundamental capability for configuring of switches
and routers. Cisco packet has logical as well as have a physical workspace.
Figure 1 Cisco Packet Tracer System
(Itechtics,2018)
The advantage of Cisco Packet Tracer
 Provide a visual demonstration for complex technology and configuration.
 Allow the instructor to customized the data and provide immediate feedback using
the activity.
 It provides more function like troubleshooting, network design activity and a case
study of the network design.

 Lab grading function
 International language support
The disadvantage of Cisco Packet Tracer
 It is not supported for summarisation manually through the amount of range.
 The default bandwidth of reference cannot change.
 It cannot change the default load balancing options
2. NetSim Method
Netsim is a software which is used for protocol, network R&D and for Defence Applications.
It is used to analyze computer network with flexibility and power. NetSim is a tool which is
used to calculate pipe network for heating. The result of the calculation represents in the
form of charts, graphs, and tables. It includes the powerful export tools which are directly
export the data to DWG and Excel format.
NetSim software allows working with Cisco. It supports 42 router and switches and device.
This is an important tool for business and classroom. It is easy to use for the design of the
network. NetSim supports a wide range of technology. It is used in the military radio
network and also in the metro rail network.
Figure 2 NetSim Cisco network
(certexams, 2019)
The advantage of NetSim:
 It is used to emulate a large amount of technology.

 It provides different types of switching, MANETs and routing for the network.
 NetSim tool is smoothly run and high efficiency.
The disadvantage of NetSim:
 It is costly.
 Sometimes it is complex to interpret the result (Abbreviations, 2019).
3. GNS-3 Method:
It has been one of the best network implementation software which is used for
implementing a virtual network and it also supports simulator for the testing of the
packet travelling. It allows the user to simply modify the network as per their
requirement. It is very easy to implement network over it.
Figure 3 GNS-3
(Source-Mark,2019)
Advantage of GNS-3
 It provides the simulated topology for connected the basic structure.
 By the use, and-3 bugs can be reproduced.
 In the GNS-3 all IOS command is activated.
 In which take packet capture with Wireshark between devices simulating
rate is high.
Disadvantage of GNS-3
 It is costly in use for network design.

 In which graphical user interface rate is high.

Task 2
Designing the network:
The network will be followed as the following which has been shown in the figure below:
Figure 4: Network Design
This design will be like as given in the scenario. The Computers will be connected to the
switch and then the switch will be connected to the router then the router of one network
will be connected to another network’s router. Then that remote router will be connected
to the remote switch and that switch will be connected to the server.
We will then configure the interface of each of the networking devices that all are
connected to the network. First of all, we will configure the server interface by assigning the
static IP address to it.

Figure 5: Server interface
The server will be assigned the address of 163.4.1.2 with the subnet mask of
255.255.255.240. This will be used to communicate between different devices which are
holding the address.
Then we will configure the interface of the Computer which is connected to the network.
The address follows the address of 163.3.1.2 with the subnet mask 255.255.255.240. The
below

Figure 6: Computer Interface
The address which will be assigned statically to the router interface of the local router
interface will be 163.3.1.1 with the subnet mask of 255.255.255.240. The interface will be
configured below:
Figure 7: Router interface
The above figure shows the interface of the router that holds the following address for
communicating with other connected devices.

2. The second thing we need to configure n between the two different routers is RIP. It is the
basic routing protocol which has to be implemented in between these two for the
communication of these two different networks. RIP configuration needs to be implemented
in both the routers of different networks.
Figure 8: RIP Configuration
The above figure shows the configuration of the RIP routing protocol. This will help in
communicating the client holding the address of 163.3.1.2 to the server holding the address
of 163.4.1.2.
3. The communication is working properly is checked by troubleshooting the network. So we
will start pinging the networking devices which are connected in the given network. First,
we will check the connection of the computer by pinging its own interface:
