This unit applies to technical staff installing an internet protocol (IP) service provider network for the delivery of emerging technologies for IPTV using multicast (broadcast) and unicast video on demand (VoD) streaming.

Relevant job roles include installer of Next Generation Networks (NGN). These IP networks provide fast internet, voice over internet protocol (VoIP), IPTV and internet TV services.

2.5. Configure security measures in an IPTV network to protect against security threats

2.6. Configure the label switch routers (LSR) to provide secure methods of transporting IP packets using layer 2 protocols in an MPLS network

2.7. Configure the MPLS-TE (traffic engineering) to provide routing on diverse paths to avoid congestion and guarantee bandwidth services

2.8. Troubleshoot network according to manufacturer's specifications and enterprise procedures

3. Build and configure CDN architecture network

3.1. Build the content delivery network (CDN) architecture overlaying the routing and switching architecture of an IP network to deliver internet TV to Internet devices

3.2. Use routing and switching infrastructure to enable CDN share characteristics of each element to produce network functionality

3.3. Install and configure web cache communication protocol (WCCP) on the router to redirect traffic flows in real-time to reduce transmission costs and download times

4. Complete and document network installation

4.1. Restore worksite to safe condition according to established safety procedures

4.2. Record and store essential installation information according to enterprise procedures

4.3. Notify appropriate personnel about the completion of the task according to enterprise procedures

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:

install relevant network hardware and software

configure and test the IPTV network according to specified guidelines

configure the LSR in an MPLS network

build and configure CDN architecture network

implement secure network.

Context of and specific resources for assessment

Assessment must ensure:

a site where the installation and configuration of an IPTV network may be conducted

equipment currently used in industry

information on different protocols

relevant technical information, legislative requirements and other site and project-related documentation.

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 installing and configuring IPTV in a service provider network ensuring network security

direct observation of the candidate building and configuring CDN architecture network

direct observation of the candidate configuring the LSR in an MPLS network

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:

ICTTEN4126A Install and configure internet protocol TV in a home network

ICTTEN4198A Install, configure and test an internet protocol (IP) network

ICTTEN4199A Install, configure and test a router

ICTTEN4212A Apply advanced routing protocols to network design

ICTTEN4213A Configure and troubleshoot advanced network switching.

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.
