    7. gerrit was proposed to remove OF1.0 plugin. If this is the case, there will need to be changes for OVSDB to adapt. (tbachman, 19:20:40)
    8. networkstatic to talk about NXM extensions (dave_tucker, 19:20:47)

    12. LBaaS support. shague_ is looking at how the existing LB works in OpenStack (dave_tucker, 19:27:15)
    13. current implementation uses HAProxy (software LB) (dave_tucker, 19:27:50)
    14. we can use OVS to load-balance instead of HAProxy (dave_tucker, 19:28:42)
    15. chris is looking at how to create a load-balancer using flows in ovs (dave_tucker, 19:29:27)
    16. we are trying to create a distributed load-balancer (dave_tucker, 19:31:59)
    17. dave_tucker asks whether we can leverage more sophisticated metrics other than just heartbeat for load balancing (tbachman, 19:36:14)
    18. flaviof has been working on L3 supprot (dave_tucker, 19:36:42)

  4. Release Plan (dave_tucker, 19:38:37)

    2. M2 milestone is today (dave_tucker, 19:39:42)
    3. Release plan : https://wiki.opendaylight.org/view/OpenDaylight_OVSDB:Helium_Release_Plan (Madhu, 19:40:10)
    4. https://wiki.opendaylight.org/view/OpenDaylight_OVSDB:Helium_Release_Plan Release plan (tbachman, 19:40:27)

  5. Release Plan (tbachman, 19:41:18)
  6. HAProxy/Load Balancer (tbachman, 19:41:41)
    1. goal is to implement as natively as possible using OVSDB and OpenFlow (tbachman, 19:42:38)
    2. goal is to remove the middlebox from the network. (tbachman, 19:43:39)
    3. HAProxy is a reverse proxy (tbachman, 19:44:09)
    4. In IPVS, you have to set up the NAT-ing rules yourself (tbachman, 19:45:32)
    5. HAProxy does the NAT-ing for you, in user-space (tbachman, 19:45:42)
    6. HAProxy maintains its own table of connections. (tbachman, 19:46:20)
    7. The back end (i.e. links being load balanced across) will see all traffic coming from HAProxy’s IP address (tbachman, 19:46:41)
    8. HAProxy is stateful in the sense that traffic proxied thru HAProxy has state about those TCP connections and how they’re mapped through the proxy (tbachman, 19:47:31)
    9. Madhu asks what if we have to remove HAProxy completely, and have OVS do the load balancing. (tbachman, 19:48:01)
    10. cdub notes that advanced health metrics probably won’t be doable in OVS (tbachman, 19:55:52)
