    this is the big list of things we’re trying to get done with some
    good notes about them  (colindixon, 20:05:34)

    we talked about AD-SAL adapters in more depth now  (colindixon,
    20:06:11)
  * right now, for me, the l2switch isn’t forwarding traffic, but I *am*
    seeing hosts  (colindixon, 20:13:16)
  * evanz doesn’t quite have getAllHosts() working yet, but he’s pretty
    sure he can bang it out pretty easily  (colindixon, 20:22:08)
  * colindixon was able to pull draft 9923 and it produces host that
    look good although l2switch still seems to not forward traffic for
    him with a linear,2 topology  (colindixon, 20:25:12)

* stuff we’re working on  (colindixon, 20:29:06)
  * djx has provided a simple address tracker of our own  (colindixon,
    20:33:43)
  * evanz asks how we should convert our hosts, which can have multiple
    MACs, IPs and attachment points  (colindixon, 21:03:24)
  * the answer is for 99% of the time, there will only be one MAC, one
    IP and one attachemnt point, so we just return it  (colindixon,
    21:06:12)
  * some other workarounds would be to factor out a single host into
    multiple hosts for the AD-SAL, get the latest observation, get the
    first observation  (colindixon, 21:10:49)
  * the *right* solution for all of this would be to make there to be
    one AD-SAL host per attachment point, per addresses structure that
    we have  (colindixon, 21:11:57)

* address observer  (colindixon, 21:12:02)
  * djx wants to know what to do with our own address observer
    (colindixon, 21:14:52)
  * right now the master is working and giving us Addresses and thus
    hosts (abeit not sending traffic)  (colindixon, 21:32:21)
  * as a consequence, I think that the the simple address observer
    should be moved into it’s own class and disabled for now
    (colindixon, 21:32:44)
  * let’s call that class SimpleAddressObserver  (colindixon, 21:33:00)
  * if we want to keep it, my take was to write the data to the MD-SAL
    and use a ReadWriteTranscation to figure out if there is an already
    existing addresses that has the same MAC, IP, VLAN triple and use
    it’s ID then, if there’s none, then we make up our own Addresses
    (colindixon, 21:39:02)
  * but I think for now we should hope their stuff works and/or fix it
    so it does work for us  (colindixon, 21:39:18)

* what’s left to do  (colindixon, 21:39:25)
  * evanz is working on AD-SAL APIs, he’ll have to figure out how to
    publish and susbscribe for OSGi services  (colindixon, 21:41:58)
  * djx wants a way to track node connector status so he can tell when
    it’s down so that he can remove those attachment points
    (colindixon, 21:45:39)
  * for now, we’re going to leave the hard coding “flow:1”, hard-coding
    the fact nodeIDs are the same in both inventory and topology, and
    hard coding the fact that node-connector-id and tp-id are the same
    (colindixon, 21:56:36)
  * for now we’re also going to leave alone handling portup and portdown
    messges  (colindixon, 21:56:51)
  * although those are good things to come back to if we have time
    (colindixon, 21:57:04)
  * one next thing to work on would be karaf, but for that it likely
    make sense to reach out to amit and alex as well so that we can
    define our features and make it work across the project
    (colindixon, 21:57:58)

    (colindixon, 22:09:34)
  * André fixed and added the getCreatedData so we can see hosts now
    (djx, 00:55:46)
  * ACTION: next thing djx will look at karaf  (djx, 01:08:18)
