Hi Team,
We are done with QoS shaping implementation in OVS-DPDK(2.4.0) by making use of
DPDK scheduler library.
We have conducted some basic tests for QoS shaping and compared DPDK vs
OVS-DPDK with IMIX traffic. Please find the below test results conducted with
bi directional traffic ,
I will be publishing the patch after completing some more tests.
System Configuration :
Processor : Intel(R) Atom(TM) CPU C2758 @ 2.40GHz
Huge Page : 2M
Memory (socket-mem) : 4096
QoS Configuration : 1G rate per port
QoS Configuration CLI:
$ ovs-vsctl set port dpdk1 qos=@newqos -- --id=@newqos create qos
type=us-shaper other_config:subport_tb_rate=125000000
other_config:subport_tb_size=100000 other_config:subport_tc_0_rate=125000000
other_config:subport_tc_1_rate=125000000
other_config:subport_tc_2_rate=125000000
other_config:subport_tc_3_rate=125000000
other_config:subport_tc_period=10 other_config:pipe_tb_rate=125000000
other_config:pipe_tb_size=100000 other_config:pipe_tc_0_rate=125000000
other_config:pipe_tc_1_rate=125000000 other_config:pipe_tc_2_rate=125000000
other_config:pipe_tc_3_rate=125000000 other_config:pipe_tc_period=40
Note : We have used "Q-in-Q" traffic for our experiments as the DPDK scheduler
application is designed to work with Q-in-Q IPV4 packets.
DPDK : 2port - 2core
