Question about MessageStream.Inbound's consumer #31

hi @jonstout,

As far as I can see, after a switch starts up, function Controller.handleConnection() and OFSwitch.receive() are both tring to pop messages from the same inbound channel OFSwitch.stream.Inbound. However the former one can only deal with the OPFT_HELLO or OFPT_FEATURES_REPLY messages.

So, other messages will be discarded if received by Controller.handleConnection() ?

Correct. Controller.handleConnection only concerns itself with the openflow channel setup. Until the openflow handshake is complete everything else is ignored. Once the dpid is discovered using the ofp_features_request message the connection stream is passed along to a Switch instance.
