Scope of Project
The project is designed for the implementation of a network for a primary school. The
components that are involved in the designing of the network are for the good
implementation of the network for the primary school. The, again and again, exercise will
make the design more specified according to the given requirement and it also increases the
project effectiveness. The project design is implemented on the NetSim for the proper
implementation that provides simulation according to the user’s requirement. In the end of
the project network design, security, IP addressing, and configuration is done according to the
requirement of the primary school.
The requirement for the Project
For the designing of the network NetSim simulation software is used and this is a Boson
Network Simulator Application. There a large number of various switches and routers that
are available in this software. All the components are arranged in that such way so that all
requirements of primary school is successfully and properly achieved. The basic network
requirements are as follows:
 The network must be designed according to the network requirements over the
simulator. The router is implemented in the network so that it works properly within
the network components properly.
 The network must be implemented properly so that it can connect 10 Guest user with
each other and 50 staff of school at a single point in time.
 A server must be implemented to provide services for FTP, so the server that is
demand from the school side is FTP server
 The network must be designed over the NetSim software to achieve all network
requirements.
 The school network must have an access point where the wireless user must connect
to the network and use the internet connectivity.
 A protocol is implemented for the guest user that is DHCP so that the guest user must
get an IP address for the usage of the network (Fleischmann, Beullens, BLOEMHOF‐
RUWAARD, and Wassenhove, 2001).

Design of Network
The planning and implementation of the network are starting with the basic design of the
network. The function that is performed by the user is done by staff members, network
administrator and the network designer etc.
####
The network design is basically a blueprint that provides a basic idea that how the network
must be implemented over the NetSim simulator.
IP Address Scheme
The IP addressing of the network is done according to the network requirement. The
following table is showing the IP address of the implemented network which includes the
three major parts i.e. LAN department, Guest Department, Server Department etc.
Department Name Subnet IP Address Subnet Mask Gateway
Guest 192.168.1.0 255.255.255.240 192.168.1.1
LAN 192.168.2.0 255.255.255.192 192.168.2.1
Server 192.168.3.0 255.255.255.252 192.168.3.1
The server department has the subnet mask of 255.255.255.252 for a C class IP. This mask
will provide four IPs one for the network, last IP for broadcasting and remaining two for the
hosts. Classless IP addressing scheme (i.e. CIDR) is used for the server.
For the Guest department there are 10 users so the subnet mask of 255.255.255.240 is used
which provides IP to 14 hosts and for LAN department users subnet mask of
255.255.255.192 is used which can provide 63 host IP addresses.
