DATA COMMUNICATION AND NETWORKING
Introduction
The report is prepared for the development of a network solution for a large university
that has a new building and a ten storey office block in the centre of town. The building block
is needed to be turned into administrative and teaching space by housing 100 computers for
each of the floor in the building. The floor is needed to be isolated and the main network is
needed to be divided into a sub network. The building floor is needed to be connected to the
LAN and configured as separate VLAN for reducing congestion, packet loss and jitter in the
network. The report is prepared by demonstrating the design prepared for the building. The
number of device needed to be deployed for interconnecting each of the department is needed
to be identified and the cables used for interconnection is also needed to be identified for
increasing availability of the network. The alternatives of the backbone network design is
identified and described with the help of the WAN design. The cost of the device and the
supplier details are attached with the report that would help to eliminate the constraints for
the development of the network solution.
LAN Design
The local area network solution is designed after a detailed analysis of the current
framework of the university and the floor plan of the building block. For developing the
network the requirement is aligned and a list is prepared containing the network device and
the other needed for the development of network. An analysis is made on the emerging
technology for its application in the network and increase the efficiency of communication

between the different hosts connected in the network. A preliminary design of the network is
developed such that it can be used for the development of the network.
The technology that can be applied for development of the local area network solution
is identified for enabling the network to improve network performance. The network device
and hardware that are essential for developing network solution should be identified for the
preparation of LAN design. The main components identified for developing network solution
is Cisco 2811 series router and it is connected with two layer three switch for enabling
configuration of server.
The network devices are needed to be connected via high speed link such that
sufficient bandwidth is available to the user for performing different activity in the network.
The local area network solution is designed following the design principles considering the
privacy and security of the network. The connectivity of the endpoints is needed to be
supported and the network is needed to support consistent bandwidth and should have

DATA COMMUNICATION AND NETWORKING
support for wide range of devices for meeting the current and future needs of the University.
Multiple link should be used for connecting the core network device such that the end device
can be reached if one of the link fails and the reliability of the network is increased. For the
development of the network it is needed to be divided into multiple subnet and VLAN such
that the different departments are connected in different network. The router is also needed to
be configured with routing such that the end PCs connected in different VLANs are allowed
to communicate with the host connected in different VLAN. The layer 3 switch is needed to
be configured as server and the distribution level switch should be configured as client such
that the VLAN information are automatically transferred to the layer 2 switches.
Some extra number of IP address are kept in reserve for each of the subnet such that
the network have support for future expansion. The service that is needed by the user should
be identified at an early stage of development of the network. The current barriers in the
development of the LAN design is needed to be identified for the development of the local
area network solution and interconnect each of the department for allowing communication
between the different areas of the network. The network should be able to grow with the
growth of the University and a server is needed to be configured with email, ftp, DHCP and
DNS service such that the different needs of the user can be fulfilled. The installation location
of the wireless access point should be analysed for providing wireless coverage to the
different users of the department and increase the efficiency of the network. Encryption
should be applied in the wireless access point such that the unknown users are restricted to
access the network of the University.

Backbone Design
The network backbone is a part of the network that is used for enabling exchange of
information and interconnect the different network device located in different areas of the
network. The backbone cabling is essential for tie by the different location and work as a
centralized network and the capacity of the backbone is needed to be larger than the current
University network such that the network is efficient to handle increased loads and respond to
the different services to the network. The congestion, packet loss and jitter in the network can
be avoided with the help of an efficient backbone cabling plan. Three different types of
backbone cabling plan are created for the development of the network design solution and the
plan is needed to be tested for the selection of the best plan and enabling service invocation
for improvement of network performance. The similar kind of network device is needed to be
connected with the help of copper crossover cable and for the distribution of the network

6
DATA COMMUNICATION AND NETWORKING
copper straight through cable is used. Fixed horizontal cabling is used for connecting the
network equipment such as the router and the switch.
The core network device is need to have the functionality of aggregation,
authentication, call control, service invocation and gateway. The operation and maintenance
of the support system should be analysed for management of distributed connectivity and
connecting the different equipment’s placed in different floors of the building and provide
them service to reduce the complexity of management of the network device. Similar kind of
network topology is followed for designing the network framework for each of the floor and
interconnect each of the network device interface. Wiring closet is used for backbone cabling
and the wire is connected with the main server room for increasing the efficiency of
management of the network devices. Routing function is needed to be configured and internal
switching is needed to be done for improvement of the network performance. Parallel
backbone is also used for the University network for increasing the reliability of the network
and allowing duplicate connection for the router and switch. Parallel backbone helps in
increasing the fault tolerance of the network and serial backbone should be used connecting
more than one working network device. Switches are used for extending the network and
here the gateway, router, bridges and switches are a common part of the backbone.

DATA COMMUNICATION AND NETWORKING
Fibber optics cables are used for long distance communication since there is minimum
loss of data packets and the data packets are transmitted in the form of light waves. For serial
and interconnection of the network device cat 6 cables are used and this cables are done for a
distance of 100 meter. Cat 6 cables are a form of twisted pair cable and works in the physical
layer of the OSI model. It has the support for gigabyte ethernet and 90 meters are
recommended for connecting it with the patch panel and horizontal cabling layout. For
increasing the efficiency of the network from the electromagnetic interference shielding
should be used such that no data packet are corrupted.
WAN Design
For interconnecting different location of the network different factors are needed to be
considered and attention should be made on the goals and objectives of the organization. The
traffic generated at each of the nodes connected in the network should be transmitted to the
destination address using secure communication channel. For connecting to the different
network location site to site VPN can be used and the communication should be made
through secure communication tunnel. A firewall is needed to be deployed for restricting the
outgoing and incoming and the switches are needed to be configured with MPLS for
improvement of performance of the network. An analysis should be made on the
performance and network operation is needed to be analysed based on the throughput, latency
and other factors. Simulation software should be used for analysing the current and future
requirement of the University and enabling interdependency and connectivity of different

devices in the network. Network monitoring and management of the network is essential for
the management of connectivity between the remote location. The performance of the
application is needed to be estimated such that the network performance can be improved and
the performance expectation is available within the available budget.
The wide area network is developed with high capacity link from node to node link
and connecting it with different office location. There are different internet based network
such as VPN that is used for similar network topology at the remote end. The capacity
planning is essential for testing the load and collecting data from different activity involved
for collaborating with the different users and develop the network aligning the needs of the
network. A forensic analysis is made on the network for analysis of the problem and
troubleshooting the errors and negotiating the data traffic in the network. Planning is needed
to be done for the management of existing data and voice traffic in the network and
placement of the network device such as router, switches and the domain controller. Network
redundancy and resilience is needed to be made and the security requirement should be
fulfilled for the management of data traffic and decrease the response time of the network.
The capacity of the network should be planned for understanding the network activity and
application such as voice, email and remote access communication. The network
performance is needed to be audited and the bandwidth usage is needed to be estimated and it
should be sufficient for the design. The network redundancy and translation of additional
capacity should be analysed and the network is needed to be tested and validated with the use
of traffic generators with the use of network design software.
A questionnaire is needed to be set for the identification of requirement of bandwidth
and the number of user and application used by them should be identified with the
identification of needs of remote accessibility. What types of device that are needed to be
connected with the network is also needed to be identified and the security issues are needed
to be identified for securing the network from the external agents. Active directory should be
configured and the long term requirement of the University is needed to be identified and
group management is necessary for restricting the user to connect with the different parts of
the network.
