Introduction
Planning a network basically focuses on the topology and arrangement of network devices. The design
process varies with the available devices and size of the network. Computer information networks
basically are a medium of communication and resource sharing. In both local and enterprise network, it
connects people, supports applications and their services and provides channels and entree to resources
that basically keep the communication consecutively [1]. On the other side such as business school or
any other field, the network must be able to adjust to changing traffic barriers and be able to sustain the
consistence of data flow. This report explains network design and implementation process of a company
that has five departments and the network is divided into five subnets.
Project scope
This is a network design of an organization that has 5 Departments. This network is further divided into
five subnets. The departments are interlinked in such a way that they are able to communicate but only
the Human Resource and the Finance departments have free access to all services in the network while
engineering departments have access to file server and print server but not the department server.
Preferably, in any data communication, the project should be planned and designed in the form of the
organization information strategy context. Internet being the backbone of network today, it will be
implemented in the network. The following are some of the goals that this process will aim to fulfil [2].
 Verify the goal and the need of the network plan and implement it
 To determine the basic features and functions that are to be implemented.
 To create a solution and an acceptance test plan.
After all this have been attained, the proposed network plan will be implemented. Communication is
very vital to any business organization and thus the implementation of a network that is scalable and
meets the requirements of the 5 departments will be the main objective. It requires an overall strategic
vision that is comprehensive and detailed enough to be useful.

Project Requirement
These are the components that are required in order to keep the networking functioning. They include
hardware and software components or network topology. The least likely traffic for such dedicated
network is the way you project it. On the other hand most network have only few requirements [3].
 The network should be able to manage up time, even in the scenario of failure links, apparatus
disappointment and loaded situations.
 The network must be efficient and be able to give reasonable times from any client in the
network
 The network must be an end to end, meaning secure. It should encrypt the data and
communication that is being conveyed across the network and information put away on the
gadgets that store over ut.
 The network basically should be easy to maintain and modified to adapt to network growth and
to change the field in which things are done. When failure occurs, then troubleshooting should
be easy.
By doing this, when inspected carefully it should translate into four fundamental network goals [4].
 Availability -organize intended for the accessibility is the one that conveys steady and
dependable execution. To include it up disappointment of a basic connection of hardware
ought not connote and effect to the system execution.
 Security - this is one of the core features that must addressed in the network. Not included
after the system is finished. Arranging the area of security gadgets, channels and firewall
highlights is basic to safe guide organize assets
 Scalability - this can grow to include new user groups and remote sites and can support new
applications without impacting the level of service delivered to the existent service
 Manageability - this matters how great the present system configuration is, the system
accessibility staff and furthermore should have the capacity to oversee and bolster the system.
A system that is excessively mind boggling, making it impossible to keep up can't be utilitarian
viable and productive.

The network was designed using hierarchical method in order to meet the goals of the company. This
design method makes networks to be more flexible and manageable than other kinds of design.
Network design
This is the arrangement of different devices in the network [7]. The goal of the Network Design
Approach is to make a network which is highly efficient. This fuses how accommodating to
accommodate the network similar to its usage, sensibility, and reasonability and how well the network
mapped to the customer necessities. The following are some of the of the periods in network designed
in accordance to human centric design.
 Evaluating orchestrate design: Network engineers do usability testing to get customers'
contribution of the framework. Framework evaluation is a critical development in arrange
change which gives essential contribution of the framework plan.
 Create Design courses of action and progression: Based on sort out framework destinations and
requirements, start an iterative method of framework plan and change.
 Specify setting of usage: The investigation has perceived who the fundamental customers of the
framework setup are are, the reason they will use the framework plot and their essentials and
under what condition they will use it.
IP address table
Depending on a layout of the network and its formation, IPs are divided into 3 classes: CLASS A that is
composed of 224 nodes which is addressed from 1.0.0.0 to 126.0.0.0, CLASS B ranges from 128.0.0.0 to
191.0.0.0 and CLASS C is regarded as baby since it ranges from 192.0.0.0 to 223.0.0.0 [6]. That is all
without sub-netting. Our network will have .Class c will be utilized in the network. The IP addresses will
be allocated to computers will range from 192.168.1.1 to 192.168.1.155.Routers will be configured with
the following IP addresses.
Device
name
IP address Subnet Mask Effective Hosts
Router 1 10.200.2.1 225.255.120.0 2 32766
Router 2 10.200.3.1 225.255.192.0 4 16382
Router 3 10.200.4.1 225.255.224.0 8 8190
Router 4 10.200.5.1 225.255.240.0 16 4094
Router 5 10.200.6.1 225.255.248.0 32 2046

In conclusion, the above network is ready and set to for the school based communication between
different departments and is able to meet the threshold of the requirement needed.

Network Topology diagram
All the networks are organized in a layered approach. The model has 3 basic layers which include: Core
layer that simply connects layered devices, Distribution Layer that interconnects the smaller local
networks and last is the access layer which connects devices to the network [5]. Using of Hierarchical
networks is more advantageous than flat design since it can easily be managed and expanded. The
diagram is as shown.

Router configuration
Each router was configured differently in the network as shown in the table below.

Switch configuration
The switches were configured will be configured with Vlan commands in order to forward the packets in
the network.
DHCP configuration
Client routers will be configured with DHCP property so that they can auto allocate IP addresses to client
computers .This will make it easier for any computer within the department to connect to the network.
Without being configured with static IP address.
Server configuration
There are different types of server in the network. Firewall security will be implemented to prevent and
block some users from accessing the network. Servers will be configured manually with static IP
addresses to be uniquely identified in the network.

Conclusion
The network was designed using five routers each department is linked to its own router. Some
departments will be prevented from accessing some servers. The Administration department is able to
access all servers that are found within the network. Implementation of the network using star topology
will make it faster since the topology has no packet collision.
