UDP packet size on torrent. #159

Closed yutayu closed 5 months ago

yutayu commented 5 months ago

Torrent clients ( qbittorrent , deluge and so on ) use not only TCP but also UDP packets. Torrent clients called it UTP connections. To avoid those connections from congestion , UDP seems to check dropping packets.

When Cake qdisc drops packets , UDP packet size grows smaller and getting smallest according to tcpdump -n -p udp. It seems that this is also TC command problem.

I don't know what to do to avoid those situation.

I mean , when cake drops udp packets , utp connections thinks ' this connection is too crowded '.

This is not cake problem. Excuse me.
