Title:
QoS API parameter name issue, max_burst_kbps should be
max_burst_kbits?
Status in neutron:
New
Bug description:
Hi,
When I check the QoS API reference, I have question about the max_burst_kbps
parameter in the QoS bandwidth limit rule API, the parameter
name(max_burst_kbps) means it's measured by the kbps, not measured by the
size(kbits).
But after I checked the implementation, with OVS for example, QoS setting
call the following fuction in OVS, the burst means the buffer size, not the
speed, and I don't see any translate for this parameter in neutron code.
/* Attempts to set input rate limiting (policing) policy, such that up to
* 'kbits_rate' kbps of traffic is accepted, with a maximum accumulative burst
* size of 'kbits' kb. */
int
netdev_set_policing(struct netdev *netdev, uint32_t kbits_rate,
uint32_t kbits_burst)
{
return (netdev->netdev_class->set_policing
? netdev->netdev_class->set_policing(netdev,
kbits_rate, kbits_burst)
: EOPNOTSUPP);
}
also, when I checked the following devref, has the following description:
• QosBandwidthLimitRule: defines the instance-egress bandwidth limit rule
type, characterized by a max kbps and a max burst kbits.
<http://docs.openstack.org/developer/neutron/devref/quality_of_service.html>
So, I think the max_burst_kbps is actually means max burst kbits, am I right?
And if I'm correct, is it possible to change the parameter name to
max_burst_kbits?
Correct me if I'm wrong.
thanks.
