| 10:17:42 | bauzas | with the minimum bandwidth model, we said "heh, we have an agent which has bridges for inter-node communication' so we are going to put resources to track on those bridges | |

| 10:18:31 | bauzas | correct ? | |
| 10:18:31 | bauzas | correct ? | |
| 10:18:32 | sean-k-mooney | yes mainly because the bandwith is an aspect of a nic which is attached to at most 1 of thoes briges | |

| 10:19:01 | bauzas | so, local vm-to-vm communication thru br-int isn't guaranteed, right? | |

| 10:21:38 | gibi | * gibi free until the top of the hour, then need to jump to two consecutive calls | |
| 10:21:56 | bauzas | * bauzas had to skip his usual Friday gym session :p | |
| 10:25:29 | gibi | in theory I we can rename the OVS Agent RP to br-int. It would help with some mental modelling. But this can be done any time independently of my work. So I would like to push this work to be a burden of the person who proposes the multiple OVS per agent spec. You can hate me for it, but I don't believe we ever get there. So I spare some effort not to do someting that will not be needed. | |

| 10:28:29 | bauzas | the main difference between pps and bw features is that one cares about inter-host communication while the other cares about the agent itself | |

| 10:29:29 | sean-k-mooney | bauzas: kind of yes. one is inter host and the other is any traffic that passes though ovs bot inter and intra host traffic | |

| 10:32:47 | gibi | until the agent and the switch has 1:1 relationship you can attach resources to the RP for both reasons | |
