Burst is a feature that allows to satisfy bandwidth requirement for additional bandwidth even if required rate is bigger than the package speed for a limited period of time.
Contention is the number of users sharing the same data capacity. The lower the contention ratio the higher the quality of service. A 8:1 contention ratio means that up to 8 broadband customers are sharing the same bandwidth at any one time.
Bandwidth distributed during load on network, higher the priority the more bandwidth available, meaning packages with high priority will get prioritised to get the needed bandwidth first before medium and low.
Shaping is bandwidth management technique that delays the flow of certain types of network packets in order to ensure network performance for higher priority applications. Traffic shaping essentially limits the amount of bandwidth that can be consumed by certain types of applications. It is primarily used to ensure a high quality of service.
FUP (Fair Usage Policy)
If you use more than a certain, predetermined ‘fair’ amount of data in the month your line speed will be slowed down, in order to allow other users to access the network fairly. Each line speed has its own FUP threshold.
