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 % expansion of the current business and the network framework is restructured for the 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.
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 (Vo et 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.
Ethernet innovation can be utilized as a part of numerous ways:

The different types of networking devices which would be required for the concept of the usage of the procedures are routers, switches and firewall (just to name a few). 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 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:

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 buy the interworking suitable device for each of the layers of the hierarchy, avoiding the aspect of the expense on pointless layer of the highlights (González et al. 2016). 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 related to administrative. If the concept of the adaptability is noteworthy objective, 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, Bekta? 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.
As it can be seen that there are 4 hosts at the bankstown home office and 2 hosts at Epping, topology of mesh which will be better option in this context. But it can be seen in the concept of Chatswood and Leichhart with 52 and 25 host respectively and hierarchical topology will be appropriate.
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 using the development concept (Alshamsi and Diabat 2015). 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
The wireless network can be considered a best option for the organization. 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 Keizer et 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.
