LAN Plan, Design And Implementation For E-commerce Business Expansion

Project Scope

This documentation is a proposal for network implementation for a primary e- commerce business. The organization which is merging two small business into one business is migrating into a story building to occupy the first three floors. The project aims at designing a network that will support all the businesses to run more efficiently than before. The first floor is divided into three rooms, reception, foyer and a warehouse. At the reception point, it will have five workstations for employees. The warehouse room will contain four computers and the foyer room will have two workstations. The first floor which will have five offices and 40 cubicle will have a wireless access Point at one of the offices. Each office will also have a data point. The second floor will be divided into four rooms with a meeting room. The wireless access point will be mounted in the meeting room so that guests can use the Wi-Fi during special meetings. Each room will have data points for employees. IP phones will be used for calling the service room any time any support is required.

This project aims at designing network for the e-commerce organization. The organization is expecting a high speed internet connection that will be used by the employees in their daily activities. The organization which occupies the first three floors of the building will be divided into several rooms. Each room is required to have a workstation. Each building is also to be fixed with a wireless access point for Wi-Fi connection. The network will be secured so that only authorized personnel will access it. So here we will design the scalable and efficient network that will meet the organizations requirements [1].

The volume of hardware components that are required in any given network design depends on the available number of users and the budget plan of the organization. While on the other hand the type of hardware devices required in the network depends on the data type that will be required to flow in the network [2]. Datatype that is required will be reports, web applications and files like bulletins. Here we will have several components that will be used in the system in order to make the network faster and efficient. The following devices will be used in the network.

Computers: They will be used as end devices for internet connection.

Ethernet cat 5: These are cables that will be used for connecting the network devices.

Fiber cables: They will be used for fiber connection between LAN switch and the fiber switch.

Servers: This will be the data center where information will stored in the organization [3].

Switches: These are devices that are used to expand the network in any connection.

Cameras: They will be used for security purposes.

The total cost that will be used in implementation will be $540020.

The operating systems that will be used in the network implementation are windows 7 and 8. They will run from different parts of the system. Windows 7 will run from the client side. This means that all the desktop computers will have windows 7 operating system. These client computers will have applications like Microsoft word and access running on them. While from the server, windows 8 will be installed since it more secure than Windows 7 [4]. The server will store all the important information about the organization. Website database and other business applications will run from the server side.

Network Hardware Components

Two or more accounts will be created in the computers that are owned by the organization. One account will be for the user while the other account will be owned by the network admin. Users will have limited access to the network as compared to the management team. Users will perform functions like reading and updating information on the system. The network will serve almost a maximum users of 150 employees [4]. Wi-Fi will support and connect to all employees devices after they have registered with the network admins. Any device that will not be registered won’t be able to connect to the wireless network.

In order for the network to be more secure, firewalls will be installed in the network. Firewall software is used to prevent the system from being attacked by viruses and malicious codes that may cause or hinder the functioning of the system. Wireless networks at each floor will have different passwords to make the network more secure. Wireless network passwords will not be given to individuals [5]. The network admin will be the one to connect users’ devices to the network. To prevent attackers from cracking the Wi-Fi passwords, they will be encrypted using AEs algorithm that is very difficult to be cracked.

Other equipment that will be used in the network will include UPS, repeaters and hub. UPS is an electronic component device that controls the shutting down process of devices in case there is power loss. Repeaters on the other hand are devices that are used to increase the strength of a signal while routers are the devices that are used to forward packets in a network. They find the shortest path in which a packet travels from its source to the destination.

The system will have data recovery plan on all servers in a secondary hard disk. Also some of the data will be stored in the cloudy for the system to be more secure. The data recovery plan will use windows backup system to save data in the secondary hard disk [6]. The system will be set with automatic data recovery plan every night at the end of each week. Fundamentally, windows restore plans of windows seven will be installed in the systems in order to recover data when it is deleted by mistake by users.

The first active directory will be installed in the domain server named www.business.com. Three groups will be set in this domain type which will include the administration, staff and other employees working for the company. These groups will be given different limitation of access to the system.

The following diagram shows how the network components will be arranged in the building.

Above is the design network diagram that will be used in the network implementation. Each floor will be connected to its own switch as shown above. The switches can then be extended by connecting to other switches in order to increase the number of ports. The switches will be linked together using a router.

Security

The above is the network diagram of the ground floor. The floor will be divided into three rooms which will be the reception, foyer and a warehouse. The reception which is located at the entry door of the building will have five workstations as shown in the above diagram. Each data point will be connected to the switch using cables to form star topology. The floor will have one printer that is linked to the network and will be located at the reception room. Also Wireless access points will be located at the reception room. The reception will have one IP phone for making calls to other offices. The warehouse will have four workstations and IP phones for calling while the foyer room will only have four workstations.

Above is a network diagram of the first floor of the building. The floor will consist of five offices and forty open cubic offices. Each office will have two workstations and each cubicle office will have one data point. The wireless access point will be mounted at the open office. A printer will also be located at the open office. Each room will have an IP phone for calling. Servers will be also be located one of the five rooms. They will be connected to the switches through fiber cables. The server room will have several firewalls for security purposes

The second floor will be divided into three offices. Each office will have two data points. The floor also has thirty open cubicle offices. Each cubicle office will have a workstation. The wireless access point and the printer will be located at that meeting room. IP phones that will be used for calling the service desk will be in each office. The cubicle offices will only have one phone.

Devices that are used in the network will be configured using different commands. The following is the IP address table [6]. It contains IP addresses that will be used in configuring the network.

Device	interface	IP address	Subnet mask	Default Gateway	Switch port
Router	Ga0/0	192.168.1.1	255.255.255.0	n/a	n/a

Conclusion

The project was successfully designed for the business organization. The business organization which contains 150 employees. The proposed network will have high-speed and support the   large number of users.it is designed to be more efficient and scalable and to serve the organization in 24hrs every day. The star topology implemented will make the network faster since it does not cause data collision in the network.
