We constantly check our CVC capacity. You can too

What are Connectivity Virtual Circuits (CVCs) anyway?

CVCs. POIs. Bandwidth. Ping. All these network terms can be confusing and overwhelming to the layman, and CVCs are easily the top offender. The best way to understand CVCs is to think of it as the bandwidth relationship between us here at Aussie Broadband, and nbn® co - the company who owns the nbn® infrastructure.

In the same way that if you have an nbn® 100 plan, the theoretical “maximum” bandwidth you can get is 100Mbps, CVCs determine the “maximum” bandwidth that Aussie Broadband can get from nbn® co in your specific location.

Confused? Sorry. Let's do a car metaphor. You're driving home from work on the Monash. Even if the speed limit (your nbn® plan) is 100km/hr, you probably won't be able to actually drive that fast due to the congestion on the road (and probably some annoying roadworks). But let's imagine you can magically, instantly add and remove lanes from a road. We (Aussie Broadband) can purchase additional lanes (CVCs) which eases the congestion and gets you back to your 100 km/hr speed limit. Home in time for The Block!

Your nbn® CVC on full display

When you look at the CVC graphs above, what you're seeing is the amount of CVCs we have purchased for your POI (the blue line) versus the actual usage of all the people serviced by that POI (the black and green lines) for the last 24 hours. If the black line ever goes above the blue line, that's bad, and means you won't be getting the internet speeds you paid for.

We continuously monitor our POI CVC graphs and if usage starts to approach the current limit, we upgrade capacity.

Sometimes, larger-scale back-haul upgrades can take time and in those cases, we will stop selling to new customers on a POI when usage exceeds an acceptable level, so that existing customers avoid congestion.

Stop-sells are lifted when upgrades are complete.

If you are experiencing speed issues and it's not showing on your CVC graph, we recommend calling our support team on 1300 880 905 as there can be other causes (such as local Wi-Fi interference).
