1 INFORMATION SYSTEMS NETWORKING ESSENTIALS ASSIGNMENT Executive Summary The report is prepared for the preparation of the wireless network solution for the Advanced Digital computer company. The WLAN has a recent growth of the computing industry and the application of the wireless network helps in reducing the cabling cost and the complexity of the network. For the development of the network the guidelines of the cross merchants should be followed and an estimation should be made for the network device required for the development of the WLAN network solution. The security of the wireless access point installed in different location of the network should be analyzed for securing the access off the wireless access point deployed in the network. The current challenges faced by the organization should be mitigated and the network design is made flexible such that it can accommodate the growth of the organization. The device interfaced for each of the device used for connecting the different branches of the organization should be configured with the dual stack address i.e IPv4 and IPv6 such that it can communicate with the network configured with the IPv6 address scheme.

3 INFORMATION SYSTEMS NETWORKING ESSENTIALS ASSIGNMENT Introduction The report is prepared for Advanced Digital Company that have a city head office, 3 branch office and 2 home office. The network is designed for supporting the retail business of the organization and the currently it have a WAN connection between the sites and the city head office. Internet access is also available for each of the branch office and the branches access the internet via their city head office. A network solution is proposed for supporting the 100 % expansionofthecurrentbusinessandthenetworkframeworkisrestructuredforthe accommodation of the growth. For the development of the network solution an IP addressing plan is created for each of the branches and the network is subnetted according to the requirement of the company such that it can meet the future needs for a tenure of minimum 5 years. A detailed network plan is designed and documented for the preparation of the report. Network Media It is recommended that the local area network should have a connectivity of 100 mbps for each of the branches connected with the city head office. The selection of the 100 Mbps Fast Ethernet can help in increasing the data transfer rate for transferring the data packets from the client server to users (Simmons 2014). An Ethernet LAN is exactly provisioned to meet information exchange speed essentials with better segments that incorporate NICs, links and also internetworking devices that can meet the most stringent requests for accessing the network. WLAN 802.11 standard is used for the securing the wireless connectivity and provide the same operating speed as the Ethernet connection (Voet al.2015). The access point should be secured with the application of encryption algorithm such that the unauthorized users does not have the access of the wireless network.

4 INFORMATION SYSTEMS NETWORKING ESSENTIALS ASSIGNMENT Ethernet innovation can be utilized as a part of numerous ways: Ethernet speed of 10 Mbps will be used at the entrance layer to give better access to customers. Additionally, 100-Mbps Fast Ethernet can be used for high-information exchange speed to customers or servers. Gigabit Ethernet can be used as the association between the entrance layer and also organizing frameworks that can bolster the system activity from Ethernet piece on the entrance interface (Karstenet al.2015). For getting the best performance from the network the bottleneck situation should be avoided and a constant bandwidth should be allocated for the transmission of the data packets. For each of the branches and the home office network different VLAN should be created such that it can be used for the separation of the network and create different channel for secure transmission of the data packets (Fleischmann and Koberstein 2015). The network should be divided into core, access and distribution layer such that the type of network media used for the connection should be analyzed.

The list basically consist of the various devices for example configuration the VPN of the remote access. These devices should be tested before the actual implementation of the aspect due to the factor that it can set aside long for the output (Wang, Liu and Szeto 2015). On the other hand it can be stated that the VPN firewall must be installed in the middle of the switch with the aspect of the approach of the VPN and a switch that directly advances movement into the framework of the

7 INFORMATION SYSTEMS NETWORKING ESSENTIALS ASSIGNMENT ground. The firewall must be the Ethernet interfaces that are basically used as a part of the network. A router or a switch directly associates with the modem through an Ethernet link done directly gives the network to different types of system. On the other hand when comparing with the concept of the router and the switch can directly able the user to interact with two system at a single time. The router requirement at each of the location would be one router. But as there 125 hosts at the office, I will directly propose five routers. For the Chatswood, it would be very much appropriate if we can use 3 routers and two routers which are recommended for Leichhart branch office. So the total of fourteen routers would be required. These routers would be directly be connected with the WAN. The switches can be used to make the traffic of the network at a very fast speed. One of the switch can be used be the server room. The major list of recommendation hardware required for the setting are given below: DeviceModelPrice RouterNetGear Wifi Cable Modem Router $120 (per piece) SwitchCisco Smart 24 port Switch$420 (per piece) FirewallCisco SA540 firewall$400 (at Head office server farm) RouterCisco 2811 Series router$2495 Network Topology In this type of scenario according to me the proposal of the hierarchical topology for HO. Utilizing a network of topology which is heretical it can be enables to limit cost. We can directly

Additionally it can be stated that the schedule idea of model empower exact the scope of the organization inside each of the layer of the hierarchy and it directly reduces squandered transmission capacity. The system administration obligation and the aspect of the system administration can be very much disseminated to the layer of the distinctive layer of the network to the control of the cost which is relatedtoadministrative.Iftheconceptoftheadaptabilityisnoteworthyobjective,the hierarchical topology is directly prescribed in the light of the fact that directly outlines that empowers the making components of the plans that can be replicated as the system (Qu, Bektaş and Bennell 2016). Since each of the example of the module is very much reliable and easy in the aspect of the analysis and design.

But it can be seen in the concept of Chatswood and Leichhart with 52 and 25 host respectively and hierarchical topology will be appropriate. Figure 2: Network design for the branch office Type of Internet Access Depending upon the ISP and the development of the associating, diverse organization are very much available like the video on demand, virus checking and the concept of the data storage. The organization must directly pick the ISP who will give a speed limit in the range of minimum 1.5 Mbps or higher from the using of the DSL advancement. The ISP must have the directly ability to recognize and involve in the concept of the information to the end customer and diverse ISP’s

Framework organization devices that are used which are part of the ISP must be awesome and can be considered to be redundant. ISP must be considered to the physical requirement for instance control and the aspect of the ventilate Thewirelessnetworkcanbeconsideredabestoptionfortheorganization.The organization can directly utilize their own DNS server due to the factor that it directly gives access to all the system administration aspect and can easily be consolidated unto the structure of the association to manage the customer’s domain. The association can directly set their own TTL value and different parameters (de Keizeret al.2015). The association which is related to the stretch keep their updates at whatever point is required. It can make the aspect of the cost very much cheap. The DNS can provide an access speed which is very much faster. Conclusion From the above report it can be concluded that with the development of the IP addressing plan the network designer can prepare the network design for meeting the needs of the organization. The selection of the network topology and the cabling plan is important for designing the network solution. The number of users using the network solution should be estimated for the preparation of the network design and preparation of the IPv4 and IPv6 address plan. The configuration of the network device must be done according to the address plan. Different VLAN should be created for the department and the wireless network such that it can help in increasing the security of the network. The servers connected in the network should be installed in the demilitarized zone such that the security of the network is maintained and the physical access of the servers are restricted for increasing the security of the network.
