Keep Alive Sample Application
=============================

The application demonstrates how to protect against 'silent outages'

+on packet processing cores. A Keep Alive Monitor Agent Core (main)
monitors the state of packet processing cores (worker cores) by
dispatching pings at a regular time interval (default is 5ms) and
monitoring the state of the cores. Cores states are: Alive, MIA, Dead
