Internetworking with TCP/IP Assignment -

Learning outcomes - Upon successful completion of this subject, students should:

• be able to explain the TCP/IP architecture and layers and compare with the OSI layers;
• be able to analyse IP addressing requirements and design an addressing scheme;
• be able to analyse the requirements of IP routing and choose appropriate routing methods;
• be able to demonstrate how internetworking devices obtain their network configuration;
• be able to explain how data flows through the internet;
• be able to ascertain and evaluate selection of applications and protocols for transferring data across the internet; and
• be able to discuss the evolution and ongoing change of the internet.

Assessment item 2 - Networking Fundamentals

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 e

ntire 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.

Question 1 - 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 - Complete the Hands-On Projects as listed in the Online Lab section of Module 2 from the subject interact site. In order to complete these activities, students should insert screenshots in the assignment document along with a brief informative description of each step taken to complete the project. Marks will be deducted if the description is not provided.

Question 3 Case study task - Advanced Digital Computer Company needs to subnet their allocated network address 192.168.128.0/20 for their corporate network, given in the diagram attached (Figure 1).

Complete the table below according to the following requirements using the original network address 192.168.128.0/20:

1. Use VLSM addressing, ie theminimumnumber of bits to include all required hosts.

2. The gateways are the last usable host address(es) of each subnet.

3. The printer is the 5th usable host address of each subnet, except for the WANs.

Assessment item 3 - Network Design (Research) - Length: 500-700 words

Task - In this assessment, you are required to read Assessment 4 (Research Network Design) and research a range of options/methods that can be used for network designing in Assessment 4. Based on your research you are required to post your views on pros and cons of each available option for the completion of Assessment 4 and select an option that you will use to complete that assessment.

In your post you must also justify the reasons behind your selection. Your post will be marked on:

• Expressing your professional viewpoint on the topic.
• Justifying your viewpoint with valid and credible evidence.

You are also required to provide constructive comments on at least one other student's post. The final marks for this assessment will be provided along with Assessment 4.

Rationale - This assessment task will assess the following learning outcome/s:

• be able to analyse IP addressing requirements and design an addressing scheme.
• be able to analyse the requirements of IP routing and choose appropriate routing methods.
• be able to demonstrate how internetworking devices obtain their network configuration.
• be able to ascertain and evaluate selection of applications and protocols for transferring data across the internet.

Assessment item 4 - Network Design

Task - This is a practical assessment and will enhance and test your practical skills related to the subject topic.

Students are required to set up a network consisting of PCs, routers, switches and servers. You will 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)

To complete this assessment you are expected to refer to information beyond the text book. This assignment is open; in that you are free to choose the devices or software you use to complete the specified tasks. Students are expected to accomplish this task by utilising the necessary commands discussed in lectures and also described in the prescribed text book. There are numerous web sites available that discuss networking , however you MUST list your sources of information for the different tasks. When completing this project, you may encounter errors or experience difficulties getting your setup to work. If this occurs, your challenge is to analyse why they happen and report on how you solved the problems you encountered.

Task 1 - Setting up a Network

Perform the following activities and support your workings with screenshots:

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 2 - Configuring Network Services

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 in your own words and all the commands used along with the output (or final result) in report format. No description or lack of comprehensive description will result in deduction of marks.

Task 3 -

Task 3 has been designed to detect and prevent unauthorized assistance with your work. This task is a question and answer session with your lecturer. You must contact your lecturer after submitting your assessment to book an individual appointment. Your lecturer will advise on how to book individual one-on-one sessions, for online students these may be over the phone or Skype sessions. Failure to contact your lecturer may result in loss of marks associated with this task.

Note - Need Assessment item 3 - Network Design (Research) - Length: 500-700 words.
