1. Introduction
Overview of Virtualmaju
The network solution is prepared for the development of the wide area network and
the different communication model is used for enabling communication between the different
departments of the organization. The Virtualmaju is a township and it is selected as the best
option for the business companies to set up their business. A design of the network topology
is created for interconnecting the buildings and meet the current needs of the business
organization for performing different business operations. The metropolitan area network is
required to be planned for assisting the user to enable communication between the different
areas of the network. Different types of communication such as wired and wireless media
should be used for the development of the network solution and different types of network
device should be used for the development of the MAN.
Overview of MAN
The metropolitan area network is developed for interconnecting the users between
different geographical locations and interconnecting the local area network. The local area
network are combined to form a single large network and creating a point to point connection
between the network devices. The metropolitan area network is designed for interconnecting
the different parts of the city and securing the transmission of data packets. The types of
network cables that should be used for interconnecting the network devices should be
identified for the development of the network solution. The different data transmission modes
should be classified for the identification of the network strategies and providing different
facilities for enabling transmission of data between the different nodes connected in the
network. The organization needs a changes and the basic needs of the organization should be
fulfilled for the development of the network solution.

2. Network Design
Detailed diagram of network design with legends
Explanation of the network diagram
The network diagram is created by segmenting the different areas and multiple
network cables are used for interconnecting the devices. The network infrastructure is created
for supporting the network and creating a reliable channel for communicating with the
different areas of the network. There are different categories such as end devices,
intermediary devices and the network media that are used for the development of the
network. The laptop, PC, tablet, routers and the access point should be connected with each
other such that different communication device should be used responding to the different
services to the network. The host devices should be able to communicate with the source and
the destination address. The network access device should be configured according to the
needs of the organization and appropriate medium should be used for interconnecting the
devices. Different types of network cables such as copper, Fibre optics and wireless medium
should be used for the transmission of the signals.

3. Media Communication
Type of media communication selected with justification
The distance of the network device and the area that should be covered is analysed for
creation of the network cabling plan. The similar type of network device should be connected
with the copper straight through cables and the different network devices such as the
connection between the switch and the router should be done using copper cross over cable.
Cat 6 cables are used for the transmission of the data packets and for the long distance
communication fibre optics cables are used. Since it can transmit the data packets at the speed
of the light and supports higher bandwidth without any loss in the transmission of the signals.
Type of media communication selected for network redundancy
The success of the network depends on the redundancy of the links of the network and
it should be used for handling the emergency condition such as failure of the link and
handling more number of request at a time. The network is needed to be configured with
frame relay such that the network traffic can be redirected using different link to reach the
destination address in the network. The security of the network should be considered and it
should be developed for securing the communication between the devices. The cost of the
network device and the cables such as the long haul links, metropolitan trunk and the speed
of the local area network should be constant such that there are no error in the data
transmission. UTP shielded twisted pair cables should be used for transmission of the data
packets within the distance of 100 meters and it is best suited for the Ethernet connectivity
and multiple links can be created such that if a link fails the nodes can use the redundant link
to reach the destination address.

The following three network device are selected for performing different operation in the
network such as:
 Cisco 2811 Series router
 Cisco 2960 Series Switch, and
 Linksys Wireless Access Points
Justification of selection
The Cisco 2811 series router is selected since it provides different functionality and
advanced service in the network. The router have enhanced module slot and integrated fast
Ethernet ports that can be used for local area connection. It has on board encryption and
provides a support for 1500 VPN tunnel that can be used for supporting the wide area
network topology. It has also the feature of configuration with Intrusion prevention system
for protecting the network from the intruders and keep the resources of the network safe.
Cisco 2960 series switch is used for increasing the productivity because it support
transmission of the voice packets in the network and management of the quality of service.
The Linksys router is used as a wireless access point for connecting the wireless device of the
office users and enabling communication of data packets in the network. The router is used
for enabling the data traffic to reach different sources in the network using different routes.
The router is configured with static routes and DHCP pool for automatically assigning the IP
address to the nodes connected in the network.
