Undertake network traffic management

Assessment tool

Version 1.0
Issue Date: April 2024


Field officers, technicians or technical supervisors from carriers, contractors or other service providers apply the skills and knowledge in this unit to manage network traffic and make recommendations for capacity planning.

This unit applies to switching and transmission networks from a carrier or service provider.

This unit describes the performance outcomes, skills and knowledge required to monitor, analyse and improve network performance for the purpose of effectively managing traffic flow in telecommunications networks.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to:

implement a contingency plan

apply short and long term solutions to traffic problems

conduct traffic measurements

develop contingencies to control traffic flow

identify potential network traffic problems and make recommendations

provide information for capacity planning.

Context of and specific resources for assessment

Assessment must ensure:

a network and equipment for traffic monitoring and management

equipment and systems manuals, specifications and enterprise policy.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct observation of the candidate undertaking traffic monitoring and management

review of report completed by the candidate containing analysis of traffic flow and recommendations for potential problems

oral or written questioning to assess required knowledge.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICTNPL6046A Undertake network performance analysis.

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

analytical skills to interpret statistical data to determine trends

communication skills to liaise with customers and technical staff to ensure requirements are known and can be met within timeframes

literacy skills to read and interpret technical specifications and related documentation and prepare reports and planning documentation

numeracy skills to make statistical calculations on traffic predictions

planning and organisational skills to develop activity plans and strategies for traffic management

problem solving skills to overcome network traffic problems

research skills to identify traffic trends and network capacity

technical skills to perform statistical measurements

Required knowledge

customer policies and service level agreements

planning principles

traffic blocking, congestion and dimensioning principles

traffic engineering

traffic patterns

transmission type and signals that may be encountered

typical network topologies, switching, routing and transmission techniques

various network management systems suitable for conducting traffic evaluations

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
