WAN Design for Tyrell Corp: A Comprehensive Networking Project

This report presents a networking project solution for Tyrell Corp's WAN design, focusing on the head office's connectivity to a service provider. The design emphasizes availability, reliability, and security, incorporating redundant WAN links and a backdoor point-to-point connection. The solution utilizes BGP and OSPF for dynamic routing, MPLS for performance enhancement, and access control lists for security. Potential failure points are evaluated to ensure quality of service. The selection of OSPF and BGP routing technologies addresses customer needs for efficient data packet delivery and reduced waiting times. This document, available on Desklib, is a valuable resource for students studying network design, offering insights into real-world application and problem-solving in network architecture.

NETWORKING PROJECT
Technical Solution meeting the customer’s requirement
The network design is created meeting the current requirement of Tyrell Corp for
interconnecting the new site, head office and the site A with each other. There is a
requirement to redirect the traffic of site B through the head quarter such that the data packets
can be monitored. Multiple links are used for interconnecting the head office with the ISP
service provider such that one of the link can be used as a backup link for handling
emergency condition. The data flow of the traffic needs to handle different situation for
choosing primary and alternative path of network traffic and the potential point of failure
should be identified for the development of the network framework (Moe et al., 2014). The
security of the network is also important for the removal of the different vulnerabilities acting
on the network. The routers should be configured with access control list such that the
unknown users are not able to connect with the internal network of the organization and
access the organizational resources. The network solution should be used for the
redistribution of the network framework and a high level design of the network framework
should be created for the identification of the technical needs of the organization (Ghali,
Tsudik & Uzun, 2014). The network diagram for the head office should be designed such that
it is reliable and secured from the external agents. A backdoor high speed is created for
establishment of connection between the site B and the head office that can be used for the
maintenance of the network without affecting the performance of the network.
Details of the chosen features works
The router is configured with BGP and OSPF for routing the data packets from
different sources to the destination address. It is used for dynamic routing such that the
shortest path is selected for transmission of the data packets. Depending on the topology of
the network the head office router is configured with OSPF such that the fastest route is

NETWORKING PROJECT
determined for the transmission of the data packets while the other routers are configured
with BGP for the selection of the shortest path and increase the efficiency of the data transfer
rate in the network (Vasilakos et al., 2015). Two routers are used in the head office for the
redistribution of the data packets in the network and two links are used. One of the router acts
as the backup router used for increasing the availability of the network. The backdoor link is
also created for connecting with the datacentre and it is configured with loopback interface
such that the network can be configured with packet filtering, identification of the device that
are online, etc. The interface of the router is configured following the IP addressing plan and
the routing table contains all the information for centrally administrating the system.
Critical Evaluation
The router is configured with multiprotocol label switching for increasing the
performance of the telecommunication network. It helps in identification of the shortest path
and it helps in avoiding the complex lookups and used for supporting a range of technologies
that is used for frame relay. The forwarding of the data packet is dependent on the data link
layer and it is used for creating a data carrying capacity for the packet switching client and
deployment of the essential goals and objectives of the network solution (Sadek, 2016). The
network is configured with BGP because it helps in management of the larger network
efficiently. The OSPF configuration is used for the internal network of the organization and
have a control of the network. For the long distance communication the head office router is
connected with a fibre optics cable and thus frame relay configuration is required for reaching
the site B without loss of data packet due to long distance communication. The failure point
of the network are evaluated for the identification of the errors in the configuration of the
routers. The real time queueing delays and the support of the network for transferring the
different types of data packets in the network are analysed for the development of the
network solution without any errors (Zhang et al., 2014). The errors in the configuration of

the network can cause increase in the delay of transmission, loss of data packets and
congestion. The evaluation of the network is important and the errors should be eliminated
such that the network can provide a quality of service for handling the data packets in the
network.
Reason for choosing the technology
Customer Needs – The OSPF and BGP routing technology is selected for the
transmission of the data packets in the network. The customer needs the network to deliver
the data packets in the network efficiently and reduce the waiting time of the network. The
customer needs to connect with the end point of the network such that it can be used for
providing connection oriented service (Masamha, Mnkandla & Jaison, 2017). The real time
queuing delay should be used for the allocation of the bandwidth for reducing the delay in the
network.
Availability and Scalability – The network device installed in the network should be
available for the transmission of data packets in different sites of the network. The network
can be expanded to accommodate the growth of the network and configuration of the network
with the requirement of the customer (Vasilakos et al., 2015). The different opportunity for
connecting the routers located in different areas of the network should be identified for
meeting different challenges and increase the satisfaction level of the customer.
Other options – There are different other network technologies such as creation of
separate vlan and dividing the network into different subnet such that the network can be
managed easily. The creation of the vlan helps in increasing the security of the network
solution and configure the network for increasing the security of the network. The access of
the data centre should be restricted to the illegal user and the router interface should be
configured with the class A IP address. The minimum connectivity speed of the network

should be 100 mbps and the range of the IP address should be specified for the different vlan
and it should be configured with inter vlan routing such that it can be used for enabling each
of the department to communicate with the other branches of the organization.
