How the nbn Ethernet product works
The product provides an Ethernet virtual circuit to deliver Layer 2 packets between the nbn® network boundaries, the Network-to-Network Interface (NNI), to the User Network Interface (UNI) at your customers’ premises. The nbn Ethernet product is composed of four configurable components. The components act as building blocks for you to tailor the nbn Ethernet product into your retail offers. The diagram below illustrates our product structure:
The nbn network features three traffic classes, to enable you to develop targeted retail offerings for key segments. Traffic classes must be ordered on both Connectivity Virtual Circuits (CVC) and Access Virtual Circuits (AVC).
There are three traffic classes:
|Traffic Class||Designed for||Access Technology|
|Traffic class 1 (TC1)||nbn’s highest priority traffic class. It is delivered as a Committed Information Rate (CIR) with defined latency, jitter and loss characteristics – suitable for applications that require highly deterministic traffic parameters such as voice.*||All|
|Traffic class 2 (TC2)||Provides support for latency sensitive, interactive applications such as video conferencing, converged business collaboration, IPTV or gaming. It is delivered as a Committed Information Rate (CIR) with defined latency, jitter and loss characteristics.*||FTTP, FTTC, FTTN, FTTB|
|Traffic class 4 (TC4)||Designed for browser based applications such as the internet and web browsing. It is delivered in a range of Peak Information Rate (PIR) speeds that are asymmetrical.*||All|
