Transient. The total number of connections that are being upgraded into usable connections in the process.\n3. Peer. The total number of connections associated with this peer. When a connection has this scope it is usable by the application.\n\nAn example of a System connection is a connection you can open a libp2p stream on and send data.\nA transient connection is not yet usable for application data since it may be negotiating \na security handshake or a multiplexer.\n\nConnections start in the transient scope and move over to the System and Peer scopes once they are ready to be used.\n\nIt would be unusual to see a lot of transient connections.
