Traffic Classes More Important Than Technology For Connectivity

The nbn™ network is being rolled out across Australia using multiple technologies – fibre to the premises, fibre to the node, fixed wireless, satellite, HFC and more.

But Aussie Broadband Enterprise National Sales Manager Aaron O’Keefe suggests that for large organisations such as local government, traffic classes are even more important than delivery technology when it comes to considering a stable internet connection.

Having worked his way up in the industry from IT Technician level, Aaron knows networking solutions from the ground up, and he’s particularly interested in bespoke telco systems for customers with multiple sites or particularly difficult challenges, such as regional locations.

There are three traffic classes available, and knowing the difference between each one could have a big impact on services for Councils:

• Traffic Class 4 or TC4
• Traffic Class 2 or TC2
• Traffic Class 1 or TC1

Traffic Class 4 or TC4
TC4 is a standard traffic class, used for delivering residential and small business broadband services. There are no guarantees around contention ratio, frame delay, frame delay variation (Jitter) or frame loss and is designed as a low cost, best effort internet service ideal for home and small business users.

For larger businesses, TC4 carries risks that most IT Managers would not want to wear.

Traffic Class 2 or TC2
TC2 is an enterprise-grade traffic class used for delivering high speed symmetrical internet and layer 2 or layer 3 WAN services. It has a guaranteed 1:1 contention ratio, and high level guarantees on frame delay, Jitter and frame loss.

TC2 is really designed to service larger organisations that rely on their internet and WAN services for voice, video, terminal services and other delay-sensitive applications and is well worth considering for enterprises such as local government, where a stable internet service is vital.

TC2 makes a great secondary or primary path in a high availability WAN or internet configuration as the the nbn™ network is independent of any carrier, the level of diversity you can achieve when using another carrier service in conjunction with an nbn™ TC2 service is very good.

This solution is ideal for those managers not willing to put all their eggs in one basket, The end game is a second internet connection that you can rely on if one of your connections goes wrong.

Traffic Class 1 or TC1
TC1 is the highest-grade traffic class, specifically for delivering low bandwidth, highly delay-sensitive applications such as bidirectional high definition audio. TC1 has a guaranteed 1:1 contention ratio, and high level guarantees on frame delay, Jitter and frame loss.
