Seth Hall commented on BIT-1363:
Coming back around to this, I just discovered (after seeing multiple references to the contrary) that AF_Packet actually does per-flow balancing which means that this isn't a viable mechanism for Bro. My testing just showed each flow of a connection being balanced out to two separate Bro processes.
Does anyone know if there is something incomplete from the configuration that was merged into Bro? I can't find anything in AF_Packet docs that I've been reading that suggests otherwise. I think that this might not be a mechanism that we are able to use for load balancing since it's not bidirectional.
> Clustered AF_PACKET support
> Key: BIT-1363
> URL: https://bro-tracker.atlassian.net/browse/BIT-1363
> Project: Bro Issue Tracker
> Issue Type: New Feature
> Components: Bro
> Affects Versions: git/master
> Reporter: Michal Purzynski
> Let's have a support for packet capture with the AF_PACKET sockets in multi worker configuration.
> Bro can use a single worker with af_packet, I have tested and it works, but having a direct support for multi-worker load balancing would allow to avoid the pf_ring for many deployments with the traffic level where DNA / ZC / Myricom / DAG is not required.
