Analysis and description of the current network Circuits The framework is made with a less response time and cabling plan is required to be used for supporting huge measure of transmission. Cisco 1900 series routers are utilized for the transmission of data packets in the network and there is no option of remote accessibility. No wireless access point are installed in the network for supporting the employees to connect their devices and laptops in the organizational network. The essential building contains the item design and the site authority and a colossal measure of movement is made from the building and therefore there is a need of working up the framework to diminish blockage and handle the request of the customer gainfully. The switches installed in the network supports VLAN configuration but it is not configured for reducing the collision of network traffic. Cat 5 cables joins the different interfaces of the devices used in the network and makes it accessible to the users. Hardware The hardware used for the employees are obsolete and affects the productivity of the employees. It does not supports virtualization and thus required to be replaced. The router is required to be upgraded and wireless access points is also required to be installed at all of the branches for connecting the wireless devices (Zhu, Crainic and Gendreau 2014). The memory and the processing speed of the employees machine is also required to be increased. Topology Software Windows Server 2008 is installed and utilized for the management of the network. Some of the desktops have free licensed antivirus softwares and other are left unprotected. For network analysis wireshark is utilized and it is installed on a PC to capture the network traffic and keep it as an evidence of any kind of attacks. Analysis A genuine and a physical framework diagram is made for the framework and it is required to be orchestrated with appropriate frameworks organization traditions for dealing with the request from the customers. The current is required to be upgraded for the settlement of the more number of centers and workstation in the working environment (Saarman et al. 2013). The present course of action uses a Hub for trading of the data packs and it is required to be supplanted with switches and switches for extending the adequacy of the game plan. The present framework have heaps of degree of progress, there is an essential of execution of the remote access point on the present framework structure for the difference in the system. Analysis and description of the proposed network Circuits For the development of the proposed network design different technology are analyzed and applied for increasing the efficiency of the current network of the organization. The main goals of the network is to increase the productivity of the employees and thus the switches used in the network solution are layer 2 and is configured with vlans for the different levels of users. Cat 5 cables of the old network is replaced with the cat 6 cables and the interconnection of the interfaces of the routers are done with serial cables. Hardware The servers are developed with multi core processors and larger memory to handle more number of requests generated from the network. The server also supports virtualization that it it can be virtualized when the load of the network increases and thus makes the proposed network flexible. Firewall devices are also installed at different points of the network for blocking the unknown request to reach the servers and increase the security of the network. Topology Software Microsoft Windows Server 2010 is used for the development of the servers and Avast Internet Security is installed on the client and the employees machine for compel virus and spam protection. There are other software required such as Corel premium collection required for designing software, Turbo Cad deluxe, etc. for increasing the efficiency of the software developers.
