Traffic Class 2
The important things you need to know when migrating business data services to the nbn™ broadband access network.
Introducing Traffic Class 2 (TC2) – Designed for business grade data services
We offer three wholesale traffic classes to phone and internet service providers (TC1, TC2 and TC4), which they use to create products to sell directly to you.# Each traffic class has a different primary purpose;
TC2 is designed to provide access to high performance data for applications and services that require consistent, predictable download and upload speed requirements – including video conferencing, network traffic over virtual private network (VPN), e-commerce and business-critical cloud services. TC2 has been designed to provide access to the following features:
- A Committed Information Rate (CIR) at a wholesale level – designed to help make performance for your data services consistent.
- Symmetrical wholesale download and upload speeds – designed to help make interactive applications like video conferencing seamless.*
- Defined latency, jitter and loss characteristics – as listed in the Wholesale Broadband Agreement (WBA) helping enable a better business grade service.
Traffic Class 1 (TC1) is designed for voice (specifically for Voice over Internet Protocol [VoIP] services), while Traffic Class 4 (TC4) is designed for general internet data (including residential-grade internet).*
With a wholesale TC2 product, your applications and services are backed by steady, consistent wholesale bandwidth with ensured throughput.* Ensure that your provider is correctly matching the bandwidth requirements you have at each of your sites.
Because TC2 is designed for interactive, real-time applications like video conferencing, as well as cloud-hosted platforms and services, it provides wholesale symmetrical download and upload speeds to providers.*
TC2 is designed to provide predictability for interactive business grade applications like video conferencing and help ensure that your staff and customers enjoy a high quality user experience.*
What kind of applications and services need TC2?
The more important the application or service is to your business, the more appropriate a plan based on TC2 could be. Consider a plan based on TC2 for real-time interactive applications like video conferencing, as well as applications central to the customer experience like e-commerce transactions.*
