NETCONF Session Overview
The NETCONF server communicates with client applications within the context of a NETCONF session. The server and client explicitly establish a connection and session before exchanging data and close the session and connection when they are finished.
The streams of NETCONF and Junos XML tag elements emitted by the NETCONF server and the client application must each constitute well-formed XML by obeying the structural rules defined in the document type definition (DTD) for the kind of information they are exchanging. The client application must emit tag elements in the required order and only in the allowed contexts.
Client applications access the NETCONF server using the SSH protocol and use the standard SSH authentication mechanism. After authentication, the NETCONF server uses the configured Junos OS login usernames and classes to determine whether a client application is authorized to make each request.
