Introduction
In this era, the use of computers has greatly influenced many operations in the business.
Networking is the process of sharing resources such as the printer, information or data in a
specific network or over the internet. The network is for connecting people together as if they are
in one platform, where they support all the services, the applications, and thus offering
provisions such as accessing the resources needed in keeping the business running for long.
Requirements of the Network.
In any area, when installing the internet that is economy-based, all the demands rotates around
meeting the customer services (Leon, 2015). In many cases the main objective is meeting the
requirements and at the same time offering protection against all insecurity incidences. If the
above considerations are met, then it will be easy to adjust to traffic changes in maintaining the
consistence loads and thus the response time becoming consistent (Network11, 2015). In
completion of any single network, there are major requirements that must be met in making sure
the needs of the user are met in all ways (Cisco, 2011).
1. Network Scalability.
2. Network Availability
3. Network Security.
4. Network manageability
Three-Layered Hierarchical Network Design
This is a type of networking that groups devices in multiple network. In Hierarchical design, the
networks are organized in layers and in this case, it will have three layers thus the name Three
Layered approach. The first layer is called Core Layer as it connects all the devices in the
distributed layer. The second layer is the distribution layer that is used for interconnections of the
networks, which are small. Last and third layer is the access layer that offers provisions in
connecting the network hosts and the end devices. The diagram below has been used to explain
the lookout of hierarchical network design.

Tools Applied for Implementation
In development of the network design, some tools are used for designing the topology or the
layout of the anticipated network can be clear when doing the implementation. Some of the
major tools are such as the use of Cisco packet Tracer and GNS3 among others.
Cisco Packet tracer
This is a tool that is very helpful and that is used when one is networking, switching, routing and
sometimes maybe over the internet. It is known for offering provisions of visualizations which
are very clear especially when is still on the sessions of networking.
