Hello:
Context: try to develop a driver for this feature in OVS.
During the last week I’ve been testing several scenarios to make a POC of this
feature.
Scenario 1:
3 VM connected to br-int, sending traffic through br-physical to other host (an
external physical machine).
The first VM will have a min BW of 15 Mb. The physical port will be limited to
20 Mb, so for VM2 and VM3 should be only 5 Mb of available BW.
Those three VM are using iperf to inject traffic against the external host.
A) One qos policy and queue is created at VM1 port (with
other_config:{min-rate=15000000}). The traffic is not shapped.
B) Another qos policy and queue with this minimum BW is created at
int-phy-patchport. The traffic is not shapped.
C) Another qos policy and queue with this minimum BW is created at
phy-int-phy-patchport. The traffic is not shapped.
D) Another qos policy and queue with this minimum BW is created at physical
port. The traffic is still not shapped.
In OVS all traffic from VM1 is filtered to match the correct qos and queues at
the ports.
Scenario 2:
Similar to scenario 1, but using a fourth VM to act as server. In this case,
traffic only goes through br-int.
A) One qos policy and queue is created at VM1 port (with
other_config:{min-rate=15000000}). The traffic is not shapped.
B) Another qos policy and queue with this minimum BW is created at output port
(VM4 server port). The traffic is still not shapped.
I need some help with this implementation, because I’m running out of time an
ideas!
Thank you in advance.
