COIT12206 - TCP/IP Principles and Protocols

General Information

Unit Synopsis

This unit provides you with an in-depth understanding of the role and function of TCP/IP protocols in contemporary network communication. The unit details the underlying technologies and relationships between the five network layers. You will gain an understanding of how data is encapsulated, addressed, and routed over networks. On completion of the unit, you will be able to explain the mechanisms used to facilitate communication between applications over the internet.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Written Assessment 25%
2. Practical Assessment 40%
3. Online Quiz(zes) 35%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: Student feedback
Some of the calculations in the course should be explained a little bit more clearly.
Provide additional supporting resources on the concepts such as subnetting and packet forwarding.
Action Taken
A new lecture video was released containing demonstrated subnetting and explanation of routing and forwarding.
Source: Students and Tutor
A smaller set of slides that follows the lecture more closely would be preferred
Reduce the comprehensive publisher-provided slides to match the size and content of the lectures
Action Taken
Source: Students
There are many Wireshark activities but no specific instruction or class introduction to this tool
Devote one workshop or tutorial to introducing Wireshark and provide resource links to introductory materials in Moodle
Action Taken

Some topics may need to be updated, for example, ADSL, ATM, and FTP
Review and update the underlying technologies that are presented in the unit

Unit learning Outcomes

On successful completion of this unit, you will be able to:

  1. Apply routing and forwarding principles to interconnect multiple computer networks
  2. Construct addressing schemes that achieve business goals while adhering to technical standards
  3. Illustrate the operation of application and transport protocols that are commonly used in delivering internet applications
  4. Justify the selection of network techniques and protocols to meet business requirements
  5. Apply testing and analysis tools to solve network design problems
  6. Explain the role of traditional networking protocols in contemporary technologies.

Australian Computer Society (ACS) recognises the Skills Framework for the Information Age (SFIA). SFIA is in use in over 100 countries and provides a widely used and consistent definition of ICT skills. SFIA is increasingly being used when developing job descriptions and role profiles.

ACS members can use the tool MySFIA to build a skills profile at

This unit contributes to the following workplace skills as defined by SFIA. The SFIA code is included:

  • Network Support (NTAS)
  • Problem Management (PBMG)
  • System Design (DESN)
  • Service Desk and Incident Management (USUP)

The National Initiative for Cybersecurity Education (NICE) Framework defines knowledge, skills and tasks needed to perform various cyber security roles. Developed by the National Institute of Standards and Technology (NIST), the NICE Framework is used by organisations to plan their workforce, including recruit into cyber security positions.

This unit helps prepare you for roles such as Systems Security Analyst, Network Operations Specialist and Systems Administrator, contributing to the following knowledge and skills:

  • K0001 Knowledge of computer networking concepts and protocols, and network security methodologies.
  • K0050 Knowledge of local area and wide area networking principles and concepts including bandwidth management.
  • K0061 Knowledge of how traffic flows across the network (e.g., Transmission Control Protocol [TCP] and Internet Protocol [IP], Open System Interconnection Model [OSI], Information Technology Infrastructure Library, current version [ITIL]).
