Even when not including the OUT-BANDWIDTH in 4.4.11.6, is there a way
with Simple TC to react on port types ? To have destination port 3000
given less priority than destination port 80 ?
I have tried with 4.4.19.1 and the problem still remains. The laptop
has two wget instances (ports 80 and 3000) fetching a 500MB file from
the server:
laptop <-> eth2 router eth1 <-> HTTP server
The router has the following configuration (see also attached
compressed sh_dump2) - this is now with 4.4.19.1:
cat tcinterfaces
#INTERFACE TYPE IN-BANDWIDTH OUT-BANDWIDTH
eth2 External - 100mbit
cat tcpri
#BAND PROTO PORT(S)
1 TCP 80
3 TCP 3000
During the transfer:
# tc -s -d class show dev eth2
class tbf 1:1 parent 1: leaf 101:
class prio 101:1 parent 101: leaf 1011:
Sent 548212535 bytes 362490 pkt (dropped 16, overlimits 0 requeues 33015)
backlog 0b 23p requeues 33015
class prio 101:2 parent 101: leaf 1012:
Sent 5978 bytes 41 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
class prio 101:3 parent 101: leaf 1013:
Sent 548297607 bytes 362682 pkt (dropped 94, overlimits 0 requeues 10822)
backlog 0b 121p requeues 10822
And the wget stats at the end of the transfers:
6.04 MB/s - for port 80
5.53 MB/s - for port 3000
Certainly, the dramatic difference as observed when using Internal TC
is not seen (TC configuration dependent) but I'd expect to see some
larger difference between bands 1 and 3 in Simple TC. Would that be
actually the case - to actually notice a good difference between bands
1 and 3 in such a two-500MB file transfer test ? Or should there be
more simultaneous traffic put through to exercize it more and see more
noticeable results ?
Thanks.
