9. Link Active Scheduler Must have one per segment
May have one device on segment designated as backup
Issues Compel Data message (Highest priority activity) - Sends message to device Device receives Compel Data message - Device then “publishes” its data - Other devices configured to receive the data (Called “subscribers)
Maintains Live List Periodically sends Probe Node messages to addresses not on the Live List Broadcasts changes to all devices
Issues Pass Token for unscheduled communication ”
