Corporate Business:
Tech Solutions is a company that deals in creating software products for different businesses. It is a small company consists of 20 employees. A sperate office room has been given to each employee with a cell telephone, a lap-top computer. Each computer has a wireless network card and a wired network card so that it can be utilized as a workstation and a mobile laptop outside an office.
Tech Solutions has been divided in to two sections. One section is manufacturing section that handles the final software products, its delivery and its maintenance. The other section includes secretary, president, chief financial officer, engineers, sales and marketing employees.
I have been appointed as computer network designer and administrator to design and implement a computer network for Tech solutions.
Let’s analyze networking requirements of the company.
Network Requirements:
There must be separate office for each employee. Each employee must be given a cell telephone, laptop having wireless network card and wired network card.

Linksys switches enhances the data paths of wired LAN to information superhighways with gigabit switches. It increases performance and enhance the quality when large files are sent over the network at gigabit speed. There is no need of additional outlets to carry electricity to it connecting devices.
BV-Tech 18 Ports POE switch is a 18 port switch. It has two Gigabit uplink ports to allow communication without sacrificing any POE ports. It has LED indicators on all ports for data.
TP-Link is a 16-Port Gigabit rack mount easy smart web managed POE+ switch.
It is recommended to apply Linksys Business 16-Port network switches to connect network devices.
A Gateway:
Gateway is a networking device that can connect two different networks. In the above scenario we need gateways to connect internet to two LANs and the DMZ. Both LANs and DMZ are different network for internet. It can also act as firewall. The firewall can be used for NAT to the LAN and port forwarding to the DMZ.

A Bridge:
A bridge is different then a gateway. A bridge can be used to filter traffic by utilizing both MAC addresses and network card addresses. It can also filter traffic using iptables rules. It is very powerful tool as it can be used to monitor and secure a network. In the tech solutions network, Bridge can be used in the wireless network, to accept IP addresses from the DHCP server and it also secure the workstations if any infected workstation or laptop is brought within the network by blocking the traffic.

Company Space Size and layout
LAN Selection
The company Tech solutions has been divided into two sections. It is required to have to different LANs for two sections. Each Section would be designed according to the star topology. The company also has wireless network. If any device is brought in the network, then should be connected to the company’s network. The company LANs would also be connected to the Internet so that clients, employee or users could access company’s network from outside.
The overall company network would be designed using star topology. In the star topology, company’s branches communicate with the central office or headquarter. Internet would be communicating to the tech solutions office. The company office has internal sections that would be communicating with each other and outside world in the form of star topology.
The server room within the office premises would be acting as the central site. If it fails the entire network goes down and there will be no communication. The performance of central hub indicates the performance of the entire network.
A start topology is scalable. It allows network growth and changes.

Conclusion:
Tech Solutions is software development company. It is small size company. There are only 20 employees. The company has been divided into two section. Each section has wired LAN. The two LAN networks and one DMZ section is connected to internet using gateway. It also acts as firewalls. The company also has wireless network so that any laptop or computer brought inside the company can get connected to the company’s network.
As it is a software development company, it is make sure that hardware equipment must be supported for development or programming purpose. We have analyzed different network hardware products from different vendors and selected suitable product for small business and for software development purpose.
To understand the computer network design and structure, first we have created company layout plan, then Lan configurations has been shown and then cabling layout of company network has been created.
The overall cost of the network has been calculated which is approximately $14133.45. This is the minimum cost of the network; however, cost may be increased by adding more network components and applying more security to the network.
