Optical Network Design and Planning

Question: Discuss about the Optical Network Design and Planning. Answer: Network Diagram Figure: 1 Network Diagram The above network diagram portrays that a total of seven personal computer are connected to the network via wired line whereas, one laptop and one tablet computer are accessing the network through the wireless connection. In the above-designed network, diagram has total two routers and two switches. Router 1 is connected to the internet and the second router is connected to router one. Two routers are connected with two switches respectively. Switch one is connected with the router one and switch two is connected to the second router. Three PCs are connected to the switch one, and other three PCs are connected to the second switches which are subnet B and subnet A. The main network administration system is connected with the switch one. A wireless access point also connected with the switch one. A tablet computer and a laptop computer access, the network via access point which is subnet C. The subnet C network, is connected to the internet via switch and router. In the Subnet 3 netwo rk, it has wireless access to the internet. Subnet A System IP Address Subnet Mask Gateway Address PC1 172.22.0.2 255.255.254.0 172.22.0.1 PC2 172.22.0.3 255.255.254.0 172.22.0.1 PC3 172.22.0.4 255.255.254.0 172.22.0.1 Subnet B System IP Address Subnet Mask Gateway Address PC1 172.22.2.3 255.255.255.248 172.22.2.1 PC2 172.22.2.4 255.255.255.248 172.22.2.1 PC3 172.22.2.5 255.255.255.248 172.22.2.1 Subnet C System IP Address Subnet Mask Gateway Address Tablet computer 172.22.2.2 255.255.255.128 172.22.2.7 Laptop PC 172.22.2.6 255.255.255.128 172.22.2.7 The network diagram shows the various entities used in forming the network. The various other devices that need to be added to the network for ensuring the basic functionality are hub, bridge, repeater, central office server, firewall and many more. In order to understand the significant of connecting various devices, the architecture of the network need to be robust. An essential element required in the network is the Hub. Being a non-intelligent device the hub is required in the network to broadcast the data from one computer connected o the network to another device. The hub is added to the OSI model's physical layer. Thus, it has no acknowledgement of the different MAC address of the devices connected to the network. Repeater used in the network will amplify the signal while discarding the noise. Repeaters are required for broadcasting over a long distance to prevent the distorted signal. The firewall system is used for security purpose. A firewall system can be placed or connected the router, switch, or in between the internet and router. A firewall has two type of functions, one is packet filter firewall, and another one is proxy filter firewall. Packet filter firewall is used to filter the network packets, and proxy filter firewall is used to bypass the access system. A proxy server is used in proxy filter firewall to check the authorized access. A repeater can be used to in this network. The chief hardware recommendation of the network for basic functionality is a wireless router, wires based connection, and wireless NIC. The wireless router is required for the providing internet access to the components connected to the network. The wireless router acts as the hub of the wired network. Furthermore, a wired base connection or Ethernet connection is required to provide standard networking function in the network. The most vital part of the wireless network required is the Network Information Card (NIC). Usually, the laptops come with inbuilt NIC card, but in order to connect any personal computer on the desktop with the wireless network, the system must have installed NICs. To implement a wireless network few things must be considered, those are The environment creates major influence in a wireless network system. Before place any wireless access point, the environment should be checked. Application support must be enabled in a wireless network system. The application can be simple office application, like an email application, file transfer application, browsing application. It could be remote patient observing in a doctor's facility or voice telephony in a storeroom. The application prerequisites empower the network designer to indicate the material throughput, innovations and items when outlining the framework. Coverage area describes the place where users access the wireless network. The users might need only connectivity in their application. In addition, deliberately consider whether coverage is required in stairwells, lifts, and parking lots. These are hard-to-cover the area, and it can increase the wireless network device cost. By indicating the appropriate coverage, it can be avoid the extra expense for wireless network devices. Dynamic IP- Make sure to recognize whether the users are stationary or mobile, which gives evidence to incorporating upgraded roaming in the configuration. The user of mobile will move about the facility and possible roaming crosswise over IP spaces, making need to oversee IP addresses dynamically. Few users, in any case, might be stationary, for example, remote desktops. Security system describes the wireless network information sensitivity which will navigate the wireless system. The wireless network designer needs to put an authentication in the wireless network system. A robust firewall system needs to be installed in the network to provide security for communication through the network. Bibliography Simmons, J. M. (2014). Optical network design and planning.
