Table of connection modes.

Device mode	Connectivity/status	Initiator	Purpose
Active	Persistent/live	Server	After client registration server establishes peer-peer connection for live command requests channel triggered by web user interface
			Client sentinels could send event change statuses
Active	Interval/command routine	Server/client	In defined interval on server side based on configuration or policy system connects and performs commands on background
			Client sends interval defined sentinel updates
Active	Zero-base/online	Server	Heart beat protocol for devices in active mode to maintain stable persistent connection
Active/Passive	Session/online	Server/client	Requested commands related to established session by web user interface where in passive mode explicit authorization is required
			Registration request of client with meta data for system connection
			Batch updates of sentinels in passive mode
Active/Passive	Not available/offline	Server/client	Connection with client or server is lost or could not be established. Data or tasks are queuing and waiting for the connection to be established
