NETWORK DESIGN
Assessment Item 3
The following steps are needed to be performed for the development of the network:
Network topological design: The placement of the network hardware components and
connecting them with each other is needed to be determined. The design is needed to be
optimized such that shortest path is used for transmitting data between the source and the
destination address (Bertasius, Shi & Torresani, 2015). The cost for transmission of data packet
is needed to be kept minimum and cost of switching is also needed to be kept minimum for
increasing the efficiency of the network.
Network Synthesis: The criteria of performance of the network and analysis of the
component size is important. The network is also needed to be segmented and the wastage of Ip
address is needed to be reduced for increasing the efficiency and performance of the network.
Selection of appropriate network topology is important and cost of transmission is needed to be
kept minimum such that the response of the network is higher.
Network Realization: The capacity needs of the network that is needed to be fulfilled is
needed to be identified and the reliability of the network is needed to be ensured. The flow of
data packet is needed to be optimized and the information related with demand, cost, bandwidth
requirement is needed to be calculated and the physical circuit plan is needed to be created
(Shrivastava et al., 2016).
The prototype of the network is created in packet tracer and configured with appropriate
network protocol and technology for demonstration of the network design. The main cons of the
developed network in assessment 4 is that it does not have any wireless access point and thus
does not support any wireless device to be connected with the network.

NETWORK DESIGN
For the development of the network an assessment is done on the hardware devices that
are needed to be selected for enabling transmission of data packets between the client and the
server. A top down network design approach is followed for the development of the network.
Focus is given on the specific goals and required network service and application for the
development of the network (Chou, Baker & Vega-Herrera, 2016). The main disadvantage of the
approach is that a thorough analysis is needed to be made for determining the specific user
requirement and it is needed to be ensured that all the possible application and services are
considered.
The network is setup with PC, router, switches and server and dynamic routing protocol
is utilized for configuring the route between the client and the server. Different network address
are used for configuring the interface of the router and enabling transmission of data packets
between the end nodes connected with the different interface of the routers. The routers are
connected with each other with serial link and for the distribution of the network the fast
Ethernet port is connected with a layer 3 switch. The interface of the router is configured with an
IP address and it is used for the configuration of the host as default gateway and send and receive
data packet via the interface (Archana, 2015). The data packets are transmitted via the default
gateway and static IP address is used for configuring route and reach the destination address. The
router protocols and configuration is checked by pinging the local and the remote router gateway
interface and the traceroute command is used for identifying the route used for reaching the
destination address. A DHCP server is configured by creating pool of IP address and allowing
the host connected in the network for assigning of IP address, subnet and DNS address from the
server automatically. A server is configured with web service for and DNS for allowing the user
to use URL instead of IP address to access the server.

NETWORK DESIGN
The router is configured with access control list for blocking the TCP traffic and between
the WEB server and the client PC. The firewall rule is verified by pinging the client and server
and analyzing that the traffic is blocked or not. For creating a plan for the network a research is
done on the topological design that can be implemented for the development of the network
(Balakumar & Prabhu, 2016). An assessment is needed to be made for the resources that is
essential for the development of the network and it is needed to be aligned with the current needs
of the business.
