|
|
* The hnp IOF component is used in HNP processes only. It is the
|
|
* "hub" for all IOF activity, meaning that *all* IOF traffic is
|
|
* routed to the hnp component, and this component figures out where
|
|
* it is supposed to go from there. Specifically: there is *no*
|
|
* direct proxy-to-proxy IOF communication. If a proxy/orted wants to
|
|
* get a stream from another proxy/orted, the stream will go
|
|
* proxy/orted -> HNP -> proxy/orted.
|
|
*
|
|
* The hnp IOF component does two things: 1. forward fragments between
|
|
* file descriptors and streams, and 2. maintain forwarding tables to
|
|
* "route" incoming fragments to outgoing destinations (both file
|
|
* descriptors and other published streams).
