standards and the service of requirements such that the network traffic can be redirected in the
network using multiple paths. The throughput in the network should be calculated and the loads
acting the servers should be balances using MPLS for the management of the network devices.
The servers deployed in the network should be configured with multimedia service and active
directory for the management of the network. The packet should not be dropped in the network
and the router should not fail to deliver the data packet in the network. The problem faced in the
network should be identified and configuring the router with the QoS service help in reducing

17NETWORK REDESIGN
the bandwidth consumption. The type of cable used for interconnecting the network device
connected in the network should be identified and the length of the cable should not exceed 100
meter in length because it can cause lag in the network. The application used by the student and
the staffs should be able to store data in the servers in the different location of the network. There
are many condition that cause corruption of the data packets due to noise and the interference
from the wireless communication. The wireless access points should not be placed in closed
areas because the obstruction can affect the coverage range of the signal. Other systems
operating on the same frequency can also cause interference and affect the quality of the signal.
The user may face latency and jitter in the packets and the performance of the network can be
reduced. The creation of direct routes and the mesh network topology can help in increasing the
efficiency of the network.
The Quality of Service in the network can be achieved with the implementation of the following
measures such as:
 Identification of the QoS mark up and the orders for creation of an end to end link
between the user and the destination nodes for connecting with the network device.
 Use a single network element for the quality of service
 Management of the QoS policy and adding different functionality for controlling and
administering the traffic flow in the network for ensuring successful delivery to the
destination address of the host connected with the university network.
The entire network is connected with each other and OSPF routing protocol is used for
configuring the router and enabling forwarding of data packets in the routers assigned for
each of the branches of the University. The user and the faculty should be able to
communicate with each other and able to transfer different type of network traffic in the

18NETWORK REDESIGN
network. Different transmission mechanism is used for transmitting the data packets such as
TCP/IP, UDP and ensuring the successful delivery of the data packets in the network.
