we're using CoovaChilli to provide our customer Internet access with
different bandwidth. It works quite good, but we still miss one feature:
AFAIK, CoovaChilli does the bandwidth handing with just dropping packets
when the bandwidth limit is reached. This has the following drawbacks:
1. the client needs to retransmit the packet again when it was dropped,
which increase the traffic in the network and decrease the performance
(especially when using wireless access points the WLAN is transmitting
much more traffic than it realls needs and the load of the WLAN is
higher than it needs).
2. there's no way to priorize special traffic to avoid packet loss when
bandwidth is reached (e.g. when downloading something via FTP the VoIP
traffic should not be dropped, better the FTP traffic should be dropped
to keep the VoIP with stable quality).
Using tc on the clients router would be one solution to configure QOS,
but a) we don't want to configure each client router with tc (too much
work) and b) some client are connected directly with a notebook and we
don't have access to them to configure the bandwidth.
So the question is, is there any posibility to configure CoovaChilli to
priorize some traffic and drop other traffic of on client if the
bandwidth is reached? And it doesn't seem that CoovaChilli does some
packet queueing to do some QOS stuff. Is it planned to be included in
next releases? Or is there any other solution to setup QOS in
combination with CoovaChilli?
Thanks for any answer!
