Each of the local area network is connected with the internet and it uses VPN client
software for transmitting the data packets over the distributed network. An analysis is made
on the current network usage by segmenting the network, users and applications. The
network is segmented into smaller lan for each of the location and a local server is used for
connecting the internet of the branch with the other branch via the internet. SSL connection is
used for securely transmitting data packets and keep the organizational information secured
from external agents. The Lan is sub divided into multiple VLAN depending on the number
of department and users working under on that branch. The users are also managed according
to their needs of bandwidth and assigned to a high speed VLAN for improving their
performance.
