Introduction
The report is prepared for development of a modern network for a multi building campus
after analysis of the requirement of the services for the University campus. A diagram of the network
frame work is created and scope and limitation of the project is analysed for development of the
solution of the solution design. The security feature and policy that is essential for maintaining the
security of communication between the user is documented in the report by analysing the service
and policies of the organization.
Building Diagram
The following diagram is created for the demonstration of the building plan and it can be
used for the analysis of the network deployment for the university and identification of the location
of the installation of the wireless access point.
Scopes and Limitations
The main scope of the project for the development of the network are listed below:
 Selection of the appropriate technology for the configuration of the network and provide
different service to the users
 To secure the communication between the user and the servers such that the
communication cannot be intercepted.

 To use multiple link for interconnecting the network devices for increasing the redundancy
and availability of the network
 Deployment of VPN service for allowing the users to remotely access the network and
services
 To subnet the network according to the departments for allowing two different LAN
technologies to work together in the network.
 Selection of the hierarchical design model for adding modularity in the network design
allowing each of the layer in the network for performing specific action.
Requirements
The main requirement for the development of the network framework for the campus is given
below:
 Connecting the different building of the university campus with each other using the local
area network and provide different service to the students and staffs of the university.
 To secure the transmission of data and information of the network by encrypting the
communication channel and eliminate the risk of different types of network attacks.
 Allowing the network administrator to have full visibility of the network and control the flow
of data packets in the network.
 Maintaining integrity of the network such that only the authorized personnel would have
access of the network device and servers
 Installation of wireless access point and securing it with proper encryption algorithm for
restricting the unauthorised used to access the wireless network
 To create backup plan for storing the data in remote location and increasing the redundancy
of data for handling emergency situation.
 To divide the network into different subnet for reducing congestion in the network and
enable better management of the network
 To secure the routers and switches with encryption for restricting the user to modify the
configuration and increasing the security of the network and block the unused ports of the
network device
 To create an Ip address plan and configure the network device interface with the first
assignable of IP address
Solution Design
The design is created after analysis of the area that is needed to be covered with the wired
and wireless network for connecting the user from the different branches and departments of the

university. A firewall is needed to be installed at the entry and exit point of the network for
management of the network traffic and securing the network from the external agents to reach the
university server and secure the information residing in the servers. The wireless access point is
needed to be connected in different subnet such that the users connected with the wireless network
should not be able to access the wired network and the security of the wired network is not
hampered.

Network Structure
For the development of the network the hierarchical design model is selected that helps in
breaking the network into different modular groups and allow each of the layer to perform different
specific function following the requirement of the university. It also helps in simplifying the structure
and the design for easy management of the network devices. The modularity of the network helps in

ADVANCED NETWORKING
replication of the elements used for design and thus improves the scalability of the network.
Redundant links are used for connecting the network devices that helps in increasing the availability
of the network since if one of the link fails the data packets can reach the destination using the other
link available. The following are the three layers of the hierarchical design such as:
Core – In this layer the main network device are configured and connected with the
distribution layer for the management of the large local area network environment.
Distribution – In this layer the access layer is aggregated for allowing connectivity with the
different services configured in the core devices of the network.
Access layer – It is used for connecting the hosts or the end point users with the network
and enabling them access to the network directly.
Since five building are needed to be connected a dedicated distribution layer is needed for
providing network based services and sharing connectivity with the devices connected with the
access layer. The quality of service for the application should be configured for management of the
performance of the network.
Protocols, technologies and services
The protocols used for the configuration of the network device are given below:
DHCP – It is used for automatically assigning the Ip address to the hosts connected in the
network and it is needed to be configured according to the vlan for each of the subnet.
PPP – It is used for establishment of direct connection with the admin Pc and access the
network device without ant delay due to congestion in the data traffic of the network.
Frame Relay – This is used for packet switching and transmitting the voice and the data
packets using the same communication channel. It helps in reducing the communication cost for the
organisation.
NAT – It is used for mapping the port address with an Ip address for increasing the security
of the network. It also decrease the needs of the IP address and the configuration of the NAT the
router Is needed to be configured with HSRP protocol.
PAT – It is an extension of the NAT protocol used for mapping multiple devices connected in
the network into a single IP address.
HDLC – It is a set of protocol used for combining the data packets in the form of a frame and
sent over the network to verify the data packets.

Security features, policies, redundancy
For increasing the security of the network IDS, IPS and firewalls should be installed along
with the use of password based authentication for the management of the access of the network
device to the users connected in then network. The threats associated with the network should be
easily identified and the unauthorised access of the user should be prevented for keeping the data
and resources safe from the intruders.
A policy should be set for allowing the user to use the wireless service and accessing the
university server. The students and the staffs should access the server with their username and
password and should not connect any device with the wired network [2]. The use of portable devices
should also be restricted because it may contain virus, malware or spyware that can infect the device
and compromise the security of the network.
A good security practice should be followed for the network for the management of the data
traffic in the network. The flow of traffic should be monitored with the use of network monitoring
tool and the servers and the network device configuration should be backed up in remote location or
cloud servers such that if the security of the network is compromised no data is lost [1]. The
switches should also be configured with multiple VLAN such that connected with redundant
connection for increasing the availability and uptime of the network.
LAN and WAN services design and analysis
For analysing the WAN and the LAN services different types of tests are needed to be
performed on the network. The devices that are needed for the configuration of the network is
analysed and a prototype of the network is created for the identification of the errors in the final
design of the network. The number of users accessing the wireless access point should also be
identified for the configuration of the VLAN for the wireless network. The area of coverage of the
wireless network should also be identified for the analysis of the number of devices needed to be
installed for the management of the connectivity of the users using the WLAN services.

Provision of wired and wireless internet for staff and student
The floor plan of the building and number of users for each of the subnet is needed to be
identified for the preparation of the subnet plan and selection of the network topology that is
needed for connecting the users with the network. The organizational policy is needed to be
developed for enabling the users to connect their wireless device with the organizational network.
For each of the department a separate server is needed to be installed for management of the
activity of the user and it should be configured with DHCP pool for automatically assigning the Ip
address to the device connected in the subnet and reduce the complexity of management of the
network device.
Summary
The requirement of the network is listed and a solution design is proposed aligning the
current framework of the campus. There are different network technologies that are available for
the development of the network infrastructure and the protocols, technologies and services
required for the development of the network framework is analysed for the development of the
network. An IPv4 and IPv6 IP address plan is created that is needed for configuring the network
device interface and enable the different department of the campus to communicate with each
other.
