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 and it 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).
Local Distribution Servers may be deployed to facilitate the management of very large environments.
