From: Lin Huang <[email protected]>
OvS has supported packet-per-second policer which can be set at ingress
and egress side in kernel datapath. But the userspace datapath dosen't
support for ingress and egress packet-per-second policing now.
So, this patch add support for userspace egress pps policing by using
native ovs token bucket library. Token bucket is accumulated by 'rate'
tokens per millisecond and store maxiumim tokens at 'burst' bucket size.
One token in the bucket means one packet (1 kpkts * millisecond) which
will drop or pass by policer.
This patch add new configuration option 'kpkts_rate' and 'kpkts_burst'
for egress-policer QoS type which now supports setting packet-per-second
limits in addition to the previously configurable byte rate settings.
Examples:
$ovs-vsctl set port vhost-user0 qos=@newqos --
--id=@newqos create qos type=egress-policer \
other-config:cir=123000 other-config:cbs=123000
other-config:kpkts_rate=123 other-config:kpkts_burst=123
Add some unit tests for egress packet-per-second policing.
