<br>
I am trying to figure out if there are any possibilities to<br>
create an internal load balancer.<br>
<br>
Basically I would like to create the following setup with<br>
OVS and VMs:<br>
<br>
<br>
WAN LAN WAN LAN<br>
--- VM1 --- --- VM2 ---<br>
| | | |<br>
| | | |<br>
-----------------------------<wbr>-----------<br>
| OVS |<br>
-----------------------------<wbr>-----------<br>
| |<br>
| |<br>
eth0 eth1<br>
(WAN) (LAN)<br>
<br>
<br>
Those VMs operate as bridge and we may imagine having more than<br>
2.<br>
<br>
I Would like to distribute flows among the VMs based on L2, L3<br>
and/or L4 information. Is there a way to dynamically do this ?<br>
<br>
I have checked the interface bonding feature with the balance−slb<br>
mode but it seems to be appropriate for bonding physical<br>
interface. Furthermore, it uses the src MAC address which is not<br>
very relevant in this scenario.<br>
<br>
If there is no way to configure this in OVS, I am thinking of<br>
writing a user app load balancer that would be connected through<br>
multiple tap interfaces to OVS. E.g the app would receive traffic from<br>
eth0 via OVS, and select an output tap interface. This tap interface would be linked to a specific VM by configuration.<br>
<br>
Any hint would be highly appreciated !<br>
<br>
Thanks<br>
Emmanuel<br>
