ITC542 – Internetworking with TCP/IP Assessment item 2

Networking Fundamentals Value: 15%

Due Date: 07-Apr-2019

Return Date: 01-May-2019

Submission method options: Alternative submission method

Task Task

This assessment aims to develop and gauge student understanding of the key topics covered so far by answering the following questions. Answering these questions will help you build some understanding for the next assessment item as well as for the entire subject. It is expected that answers to the assignment questions be succinct (i.e. precise and concise) with all sources of information fully referenced as per APA referencing style. You have to reference the text book and any additional material you have used in your answers.

Note that the guide for APA referencing is provided in the resources section of Interact site of this subject.

Answers MUST be written in your own words. No marks will be awarded for any answer that contains more than 10% direct quote (referenced or unreferenced). One or two sentence answers will be too short and only receive low marks. Answers longer than 1.5 pages (12 point font, single line spacing) may incur a penalty if too much non-relevant information is stated. For mathematical questions it is expected that you show intermediate steps of your working. Just stating the correct solution will result in low marks, on the other hand if the working is correct and you only made minor mistakes, you will still be awarded marks, even though the final answer is wrong.

Question 1 [3 Marks]

Write functions of each layer of OSI reference model, also differentiate between hardware and software layers. Explain your view; why Network layer of OSI model is called Internet layer in TCP/IP networking model?

Question 2 [3 Marks]

Complete the following Hands-On Projects from the prescribed textbook (Pyles, Carel & Tittel 2017)

Hands-On Project 2-3

Hands-On Project 3.2

In order to complete this activity, students should insert screenshots in the assignment document along with a short description of each step taken to complete the project.

Question 3 [4 Marks]

For any data communication, MAC and IP addresses play very important role, explain why these two types of address are important and what critical role ARP protocol plays in this scenario?

Question 4 Case study task [5 Marks]

In your role as a Solutions Architect at Foreshore IT Solutions, you are leading a team of several system administrators. Foreshore IT Solutions is a large organisation and is currently expanding its operations. The company was using six sites across Brisbane to accommodate its various departments. These departments are interconnected by three routers.

Company’s current network is shown as above, which include following departments at various sites:

Site Department No of Hosts
HQ Sales 16000
  Marketing 8000
BR1 Advertising 2000
  Online Sales 4000
BR2 Product Support 1000
  Technical Support 500

Recently, company has experienced huge growth in their business, and need to employ more employees who will need more devices (hosts). Company is expecting 40% growth.

You are required to recalculate IP addressing scheme for this network to accommodate 40% growth, for example; Sales department will grow by 6400 hosts. Also provide subnets for inter router connections which should have subnet mask 255.255.255.252

Use network ID 180.XY.0.0/16 (where XY are last digits of your student ID). TASK Write a 800 words (+/- 10%) (Max) report explaining:

  • The detailed design of a simple addressing solution (with diagram(s) and step by step workout of the calculations) that accommodate for growth, is easy to administer and has the minimum wastage of available IP address space. [3 Marks]
    • Provide IP addresses and Subnet Masks for all LAN and WAN interfaces. [1 Mark]
    • Suppose in further future, this company experience more growth, which leaves company with no option except upgrading this network from IPv4 to IPv6, investigate/ explore the technical changes you may need to implement for such upgrade

Task

Task

Task 1 (Research) [5 marks]

In this task, you are required to research a range of options/methods that can be used for network designing in this assessment. Based on your research you are required to clearly list your views on pros and cons of each available option for the completion of this assessment and select an option that you will use to complete this assessment.

Task 2 – Setting up a Network [10 marks]

You are required to set up a network consisting of PCs, routers, switches and servers. You need to configure routing between routers, use any dynamic routing protocol. The PCs (clients) will be connected to switches and switches to the router’s interfaces. Clients and Servers are

connected on different networks (don’t attach clients and servers on same network). Client(s) <–> Switch <–> Router <–> Router <–> Switch <–> Server(s)

Use ONLY the IP address which you calculated in Assignment 2.

Perform the following activities and support your workings with screenshots [10 marks]:

  1. Configure the PCs, Server and Router interfaces with appropriate network addressing;
  2. Configure any classless dynamic routing protocol on the routers;
  3. On any client, ping the client’s own network interfaces, then the local router gateway interface, then the remote router interface, then the servers. Check full network conductivity;
  4. Use the traceroute command from the client to the server. Include results of the traceroute in your submission, explaining meaning of traceroute output.

Task 3 – Configuring Network Services [10 marks]:

Using the same network topology that you have setup in Task 1, perform the following additional activities

  1. DHCP: Configure DHCP servers and show that the client PC has successfully received IP Addresses and other network parameters (default gateway, subnet mask and DNS IP address) using DHCP
  2. WEB Server: Configure WEBs server on the dedicated machines in their specified networks, with URL as yourname.csu.org
  3. DNS: Configure DNS Servers on the server device and demonstrate that forward and reverse DNS are working from the client PC; test DNS Server by browsing yourname.csu.org from client PC, DNS must resolve this URL to IP address of WEB Server
  4. Firewall: Configure traffic filtering on the web servers to block ONLY HTTP TCP traffic between one of the client PCs and WEB Servers and allowing all other IP traffic, provide evidence of such traffic filtering. You should verify firewall by using PING and HTTPS TCP traffic which should not be blocked.

A series of screenshots with commentary on each of the required tasks is to be submitted. The submission must include a comprehensive explanation of each task and all the commands used along with the output (or final result) in report format.

Task 4 [5 marks]

Presentation

Please note that this assessment is asking for your reflections/thoughts and understanding of the topic. Therefore refrain from directly copying and pasting from other sources. I encourage wider reading to increase your knowledge base however proper referencing guidelines MUST be followed (please refer to the APA referencing guide in student resources) otherwise your work can be reported for plagiarism.

We have a very diverse learning group with students from different parts of the world, and it is important to respect that with such a diverse group, everyone’s ability to express themselves in written language can vary. Therefore it is important to respect diversity and opinions different from yours, no matter where they come from. Let us all also be mindful that written communication can be easily misinterpreted, therefore please be careful and avoid using strong words so we don’t cause confusion and/or anxiety for our peers.

Please ensure that (all tasks) mentioned in this Assessment must be submitted in the Turn-it-in.
