Hi, I've been talking to Shay Vargaftik (CC'd), also a researcher at VMware, about some work he's done on optimizing load balancers. What he's come up with is a technique that in many cases avoids putting connections into the connection-tracking table, because it can achieve per-connection consistency without needing to do that. This improves performance by reducing the size of the connection-tracking table, which is therefore more likely to fit inside a CPU cache and cheaper to search.
I'm trying to determine whether this technique would apply to OVN's load balancer. There would be challenges in any case, but one fundamental question I have is: is the OVN load balancer also supposed to be a firewall? If it's not, then it's worth continuing to look to see if the technique is applicable. On the other hand, if it is, then every connection needs to be tracked in any case, so the technique can't be useful. Anyone's thoughts would be welcome. Thanks, Ben. _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
