Class KeepAlive

java.lang.Object
  java.util.TimerTask
      com.ericsson.tic.vi.KeepAlive

All Implemented Interfaces:

Runnable

public class KeepAlive
extends TimerTask

KeepAlive periodically sends a message to the master system to let it know that the VI is up and running and ready to recieve messages from the master system. When the master system stops recieving messages, it will stop sending data. This was added in order to cut out excess traffic on the network.
