Subnetting Calculation And TCP/IP setting for the Scenario

 Say you are conducting a university learning platform with over 10,000 students, how do you setup the network of cloud computing for student accessing their assessments and notes? Well, the OSI layer model has already explained to you on how the data is carried from university to students computer. Now, let's take a look at how to calculate the proposed subnetting calculation. 

VLSM

VLSM Addressing Schemes. Variable-length subnet masking (VLSM) subnetting is similar to traditional subnetting in that bits are borrowed to create subnets. The formulas to calculate the number of hosts per subnet, and the number of subnets created still apply.

 VLSM stands for Variable Length Subnet Mask where the subnet design uses more than one mask in the same network which means more than one mask is used for different subnets of a single class A, B, C or a network. It is used to increase the usability of subnets as they can be of variable size.

 VLSM subnets used block size based on requirement so subnetting is required multiple times. In this situation there are 4 subnets to manage. Subnet Students with 10000 hosts, Subnet Admin with 4 hosts, Subnet Management with 100 hosts and Subnet Lecturer with 4300 hosts.

IP 192.168.1.0/24 as the network prefix because Class C IP Address is for handling huge network with large quantity of host. 

The first step in the VLSM subnet is to select the appropriate block size for each segment. The following table lists all available block sizes.

VLSM TABLE CLASS C

By referring to the table above, the host available for students are 16384 and the network address will start from 192.168.1.0. We may conclude that the available address for student to access the portal is 192.168.0.2 and upwards because the network address acts as a getaway for the servers. 

TCP/IP MANUAL

In the previous section, we have assigned IP address for Online Learning System which are 192.168.0.2 Thus, in this section we will provide a manual on how to configure the IP address on the server. The operating system use in the manual are Windows 10. The explanation will be supported with the screenshots and appropriate explanation.

1. In Search engine, search for Control Panel. Click to open it.

Figure 1 : open Control Panel

2.After Control Panel been displayed, there are many option such as System and Security, Programs, User Accounts and others but you need to click on Network and Internet.

3.Then, click on the Network and Sharing Center.

4.After you click, on the left side of the window, click the on the Change adapter settings. And then, it shows two networks. Choose the Ethernet  network to do the configuration.

5.Double click on the Ethernet 2 to get the Properties. Then select the Internet Protocol Version 4 (TCP/IPv4).

6.We must input an IP address for ULearn System Server from Question 2 Subnetting Calculation. The  available address is 192.168.0.2. The subnet mask will be automatically filled and we will leave the default gateway empty. Click OK and we will be redirected straight to the Online Learning System Server.
