This module is in charge of running an event handler for each SDX participant. This event handler receives network events from xrs module (BGP updates), arproxy module (ARP requests), and participants's control interface (high-level policy changes). It processes incoming network events to generate new BGP announcements and data plane updates. It sends the BGP announcements to the xrs module and dp updates to the flanc module.

See examples/test-ms/README.md for an example of how to run pctrl along with everything else.
