Do you know if there are any projects to shape traffic based on
thresholds on round trip time or packet loss, instead of statically
configured rates?
We subscribe to a 1.5mbit full duplex connection, and before any fine
tuning, I'm aggressively limiting up and downstream traffic to 1mbit
each, to "own" the queues:
tc qdisc add dev eth0.2 root handle 1 tbf rate 1mbit burst 5k latency
70ms
tc qdisc add dev ifb0 root handle 1 tbf rate 1mbit burst 5k latency 70ms
Right now our upstream traffic is about .4mbit and our downstream is
about .8mbit, so I guess our traffic shaping is just forwarding packets
as fast as they arrive. But today the average round trip time is over 4
seconds and packet loss is about 40%. Is it possible to automatically
reduce the rates in situations like this, until the round trip time or
packet loss improve? Then periodically increase the rates again, while
monitoring performance?
Do you know about any resources related to automatically shaping traffic
based on thresholds, such as on round trip time or packet loss, instead
of statically configured rates?
