ADVANCED NETWORK DESIGN
Project ScopeThe scope of development of then network solution identified are listed below:
The area that should be covered by the network and the number of users connected
with the network should be identified for the development of the subnet plan
The types of cables used for the interconnection of the network device should be
managed
A network diagram should be prepared with all the details of the network and each of
the department should be assigned with separate VLAN
The voice and the data channel should be separated for increasing the efficiency of the
network and reduce congestion
The subnet plan should be created with keeping extra IP address such that the network
can support the growth of the college
A prototype of the network should be configured for the identification of the error and
resolve it for increasing the efficiency of the network.
Detailed Network DiagramsThe network design is created following the requirement of the IT college where the college
needs to connect its 400 number of users of different departments. For the development of the
network solution a subnet plan is prepared and separate switches are used for each of the Labs. The
switches are configured with VLAN such that congestion is avoided and the communication cost is
reduced. The building and 2 router are configured with IP telephony for reducing the communication
cost between the departments and the Labs and each of the routers are connected using the serial
cable. A wireless router is connected with the core switch of the building for increasing the
scalability of the network and enabling the user to connect their wireless device in the network. The
development of the detailed network diagram helps in identification of the hardware needed for the
development of the network framework. The router needs to be configured with access control list
such that the unknown packets cannot reach the servers connected in the network and the network
is secured from the external agents. The development of then network also helps to identify the
type of cable and the ports used for interconnecting the network devices.

IP Addressing PlanMajor Network: 10.10.30.0/24
Available IP addresses in major network: 510
Number of IP addresses needed: 253
Available IP addresses in allocated subnets: 442
About 91% of available major network address space is used
About 57% of subnetted network address space is used
