| − | CTWUG uses a combination of WMM, DSCP marks, and queues to prioritise traffic. Traffic is divided into 3 groups namely Bulk, Interactive and Realtime. Bulk traffic has the lowest priority on the network and like its name suggest all bulk traffic, like torrents and DC, goes into this group. Interactive traffic has a high priority, this group is for protocols that require low latency and sometimes higher bandwidth, traffic like games and irc will go into this group. The last group is Realtime, this group is more for low latency dependant traffic like VOIP and has the highest priority.

| − | Here is a list of ports currently being identified by our QoS rules, please note that of a port is not listed here it will automatically fall withing in the Bulk group. To request new ports to be added please use the discussion page, and specify the application using the port.
