KNE434 Computer And Data Networks

Answers:

1. Comparison between OSI reference Model with TCP/IP Networking Model

Working with the TCP/IP networking model can be more useful in the network development as it can be helpful in enabling the full control over the network through specifying the mechanism of the information exchange over the network. It is helpful in effective and proper network management through assembling small packets of the data and transferring it over the network.  

2.Completed Hands - On Project

Hands – on Project 2 - 3

Subnet mask Calculation for the Required Number of IPV4 Subnets

The website “gestioip.net” is visited and the Ipv4 address is inputted for finding the details of the IP address. The bitmask is kept 24 for allowing 254 number of host to be connected in the network and it can also be used for mapping of the IPv4 address with the IPv6 address and configure a dual stack network for enabling communication with the network configured with IPv6 address scheme.

Hands on Project 2 – 5

IP Address 192.168.0.1: Subnet Calculation

 IP Address 10.0.0.1: Subnet Calculation

Further experiment was done on the Network class B that has an IP adress of 172.16.0.1 and following results were found:

3. ARP (Address Resolution Protocol)

The ARP to the physical machine addresses can map the internet protocol address recognized in the local network. The table namely ‘ARP cache’ is being used in general for the maintenance of the relationship between the IP addresses and the MAC address.

4.Case Study Task

Introduction

This report emphasizes network solutions for the ‘Foreshore IT Solutions’ company that has been expanding its business through establishing six sites across Adelaide in manner to allow the accommodation of its various departments. The prototype of the network design has been proposed in this report. This report also presents a “simple network address solution” for the router’s configuration has also been proposed in manner to enable the effective and efficient communication between the various departments of the Forshore IT Solutions.

Detailed Simple Addressing Solution Design

(Source: created by author)

Six offices will be having six different routers that will be connected with the central router as expressed in the above figure. The central router and the Cloud will be connected with each other passing through the firewall. This will be helpful in controlling the traffic, the interface of the router will be configured through the first IP address, and rest of the IPs will be reserved. The reserved IP will be helpful in supporting the further growth of the Foreshore IT solution company.

Major Network: 10.0.0.0/21

IP addresses: 2046

Needed count of the IP addresse: 1130

Available IP addresses: 2036

Approximately 100% space of the available major network address space has been used

Approximately 56% space of the subnetted network address space has been used

The data represented in the above table has been noted considering the needs and requirements of the Foreshore IT solution company. The table represents the complete establishment of the IT infrastructure within the six sites including 1200 workstations. Considering the assignable range of IP address and the minimum wastage of the IP address, the subnet has been calculated that is capable of presenting the favorable solution for the company. It can be recommended that can be configured with the DHCP protocol in manner to allocate the IP addresses top the hosts those have been connected to the network as per the identified subnet for each of the department. There is the need of the configuration again due to the situation of the enhancement in the number of the hosts.  There will be the need of the calculation of the subnets and configuration of the router in manner to allow the effective communication between the workstations. In manner to calculate the subnet mask VLSM, there will be the need of the CIDR in manner to establish the network communication between the routers at the workstations and the central router. The isolation process can be helpful in enhancing the security of the established network.

Conclusion

The facts presented in the above report can be helpful in concluding that the aspects related to the development of a network solution has been presented in the above report in manner to provide an efficient and secured communication network for the Forshore IT solution company. the networkn recommended in he above report will be helpful in allowing th configuration of the router using DHCP protocols and will be addressing the problems identified within the Forshore company. “If case of sudden increase of the host to1204 for each of the department the whole address plan needs to be reconfigured with the application of the new address plan.”
