Contention Ratio on National CIR

The contention ratio is the ratio of the potential maximum demand to the actual bandwidth available. The higher the contention ratio, the greater the number of users that may be trying to use the actual bandwidth at any one time and, therefore, the lower the effective bandwidth offered, especially at peak times. A contended service is a service which offers (or attempts to offer) the users of the network a minimum statistically guaranteed contention ratio, while typically offering peaks of usage of up to the maximum bandwidth supplied to the user. (Source: Wikipedia) Although this could be bit confusing, the important bit is that we promise that we will never ever oversell your national CIR. 

Network Latency

Network latency measures the amount of time it takes a packet of data to move roundtrip from one point in a network to another. To have a network capable of advanced cloud services you need a network latency of less than 50 msec. Here is an example of the results from a recent Network test.

Network Jitter

The term jitter is a measure of the variability over time of the latency across the network. Therefore a network with a constant latency has no jitter. It is absolutely vital for networks to have little or no jitter to enable VOIP services to be effectively delivered over the network. Consider jitter the gaps between data packets. High jitter is what causes poor quality phones calls and delays in video streaming.

Utlisation of Network

This figure is expressed as a percentage and shows how full our network is. A high network utilisation is also called congestion. It is expressed as a percentage of total usage and again for this we will use our connection between Auckland and Wellington* as an arbitrary measure. This will include both up and down traffic.

Contention on International Burst CIR

Exactly the same as above except for international traffic and not national. We promise that we will never ever oversell your CIR.
