The report is prepared for the development of a local area network and configure the hardware device installed in the network. The scope of the expansion of the current organizational network is analyzed for proposing the new network solution and accommodation of the growth of the organization. The floor plan of the organization building is evaluated for the development of the network design and number of data points required for each of the department are analyzed for the development of the network solution. The hardware that are essential for the development of the network solution are listed and they are used for the preparation of the network design. Cisco packet tracer is used as a simulator software for the configuration of the network and the commands are attached with the report. The prepared network is tested multiple times for the identification of the errors in the network and increase the fault tolerance in the network. Each of the department in the network are connected using different VLAN and reducing the congestion in the network.
The project scope are defined for the preparation of the of the proposed network solution for the ecommerce business organization.
The following table is created for listing the hardware that are required for transforming the current network infrastructure and meet the requirement of the ecommerce business organization.

The proposed network design is created following the data points required to be installed for each of the location. An access point is installed at each of the floor of the network for covering all the departments and increase the efficiency of the network. A layer three switch is connected with the ground floor router for making the management of the network simplified and reducing the risk of network downtime. A layer 2 switch is installed for the first floor network and interconnecting the nodes of the first floor. The second floor router is also connected with a layer three switch for easy management of the network. The data packets and the voice packets are sent in the network using different VLAN for reducing the risk of congestion and delay in communication. The routers installed in the network are configured with DHCP protocol for allocation of the IP address to the nodes connected in the network. Four server are installed in the network i.e. database server, file server, webserver and email sever. For the server the windows server 2012 R2 is used and the active directory are configured according to the business requirement if the organization. The access point installed in the network are secured with WPA/ PSK 2 for securing the network from illegal access. The firewall installed in the network are configured such that the normal users does not have access to the file and the database server and the company information are kept secured.
Frame relay, TDM and HDLC protocol are used for the configuration of the network. The frame relay uses the packet switching for the transmission of the data packets in the network and the high level data link control is used for the establishment of point to multipoint connection between the source and the destination nodes in the network. The time division multiplexing is used for the avoidance of the deadlock situation in the network and increase its efficiency.
Asynchronous transfer mode and CSMA/CD is used as a LAN protocol for the development of the network solution. The SDP and RTP (Session description and real time transfer protocol) is used for the configuration of the VOIP devices in the network.
The following are the configuration command used for the configuration of the routers and the switches used for the development of the network solution:

Conclusion
The approval of the proposed network solution is important for the success of the project and thus the report is prepared for clearly defining the structure of the network. The report would help the stakeholders to identify the security measures, hardware and the protocol used for the configuration of the network. The proposed network design is prepared after aligning it with the requirement of the current infrastructure of the ecommerce business organization. The router and the switch installed in the network are located are configured with proper protocol and commands for communicating with the nodes connected in the network. An appropriate cabling plan is used for interconnecting the departments and reduce the congestion in the network. The network is designed for supporting VPN connection and manage the network resources from remote sites. The path to reach the network resources are kept redundant such that in case of link failure the redundant link can be used for communication.
