Detailed Description

2 x LACP graph nodes: an "interior" node to process incoming announcements, and a "process" node to periodically send announcements.

The interior node is neither pipelined nor dual-looped, because it would be very unusual to see more than one LACP packet in a given input frame. So, it's a very simple / straighforward example.
