Assignment: Network Routing and Switching
Objectives
This assessment task requires you to demonstrate your knowledge of basic routing concepts by completing a number of exercise questions. The questions contain various numerical as well as descriptive questions covering the material from Weeks 1 to 9. Question #4 requires you to research further and then demonstrate knowledge of advanced concepts.
Completing these questions should help you to achieve the unit learning outcomes as listed in the unit profile.
Question 1 - Routing table construction
Given the following network in Figure 1, construct the routing table of router R1:
Question 2- Allocating subnets from a block
You are the Network Administrator for a very large IP company, you have an IP address of 10.0.0.0 and the subnet mask given is 255.0.0.0. The IP address must be divided in to 4 different subnets.
a) Calculate the total number of addresses available in this block including all the special addresses. Show your calculation.
b) As Network Administrator, you need to distribute the available addresses on a departmental needs basis (meaning not allocating more than you have to), with 4 new subnets determined as follows:
In Subnet 1, there will be 210 computers,
In Subnet 2 we will have 700 computers, In Subnet 3, 150 computers, and
In Subnet 4, 70 computers.
Create the 4 subnets. For each subnet, list the subnet or first address, the last address, and the subnet mask in CIDR format. Show your calculations for all subnets, briefly showing how you arrived at the sub-block addresses.
c) How many addresses are left unallocated? Show your calculation.
Question 3:
An Ethernet frame carrying an IP packet was captured by Wireshark. The Ethernet header was removed and the remaining data (i.e. the payload, arranged in groups for readability, left to right) is the following:

Analyse the given data for layer 3 information:
a) Identify the protocol version for layer 3.
b) Identify the header length (remember to specify the units).
c) Identify the service type.
d) Identify the total length of the layer 3 packet (specify the units).
e) Determine the identification value.
f) Interpret the flag information.
g) Determine the time to live value.
h) What is the protocol value?
i) What is the protocol used in layer 4?
j) Identify the source IP address.
k) Identify the destination IP address.
Analyse the payload of the IP packet (i.e. layer 4 segment):
l) Identify the source port number.
m) Identify the destination port number.
n) What is the length of the data? (specify the units)
o) Is it a packet from the client to the server or vice versa?
p) What is the client process?
Question 4: Advanced routing study
Research and write a report with the following content (marks allocated as shown):
1. Introduction IoT Devices.
2. Communication protocols that are specifically related to IoT.
3. IoT would not be possible without IPv6, Advantages of IPV6.
4. Different types of wireless connections used for IoT.
5. Not everyone agrees with Sigfox that a separate network is needed for the IoT. Compare and contrast with other networks.
6. Conclusion.
7. References: Adhered to Harvard reference style.
Your report should include only the introduction (about 200 words), body (about 1000 words), conclusion (about 200 words) and the reference list (Do not include the executive summary and table of contents). Use the sub-headings given in the template and include in-text references in the body of the report. Use Harvard style of referencing for the list of references and in-text references.
Your references (at least 5) may come from quality websites, white papers, government documents or published conference or journal papers.
Question 5 - IPv6 Packets
Given the following IPv6 addresses, answer the following questions.
a) What is the full (expanded) address of the abbreviated IPv6 address: FE8A::B00:27EF:FED4:10BC?
b) What is the type of block of the abbreviated IPv6 address FE8A::B00:27EF:FED4:10BC?
c) What is the type of address of the abbreviated IPv6 address 0::37.201.14.95?
