Messaging between the managed hosts and the Management Server is transmitted through a TCP/IP connection. The Management Server needs to have a public IP address. The Management Agent initiates the management connection to the Management Server and the connection is kept on continuously allowing for instantaneous management actions (for example, when pushing configuration changes).
This removes the need to open additional ports or services on the managed hosts, and the need for the server to poll for hosts that may be offline. It also enables connections through Network Address Translation (NAT).
When local Distribution Servers are deployed to facilitate the management of large environments, the Management Agent opens the management connection to the Distribution Server which then continues to connect to the Management Server.
