Hi Valentine,

this readme describes how it is used internally:

Thanks for the link. Of course, I read the manual (and skimmed through the code) before posting. :-)

The wiki page you mention says that RabbitMQ runs locally by default. It also says it's configurable, but it's unclear to me when I'd want to tweak this default. The code suggests that AMQP glues vnc-api-server to scheme-transformer inside configuration node (which I consider local execution). However, the C++ ifmap server also listens to AMQP messages, and as it runs as a part of the control-node process, this makes me assume RabbitMQ should be also available over the network.

If any of these thoughts are incorrect, I'd be happy to learn the real state of the things.

Valentine

    Hi all,

    [looks like the initial email was lost somewhere; sorry for the
    possible dupe just in case]

    I'm strugging to figure out how RabbitMQ is used with OpenContrail.
    I do understand that it is used to deliver user requests to IFMAP
    through API servers, but what I don't get if this works within
    configuration node or between nodes?

    Is there any AMQP traffic between nodes in a cluster?

    Many thanks,
    Valentine Sinitsyn
