Brrr...! It's probably a link to repulse people which want to understand something.
The control plane is for connectivities.
G.8081 (02/2012) "3.2.23 The control plane performs the call control and connection control functions. Through signalling, the control plane sets up and releases connections, and may restore a connection in case of a failure. The control plane also performs other functions in support of call and connection control, such as routing information dissemination".
The management plane is for the management functions.
G.8081 (02/2012) "3.2.44 : The management plane performs management functions for the transport plane, the control plane and the system as a whole. It also provides coordination between all the planes. The following management functional areas identified in [ITU-T M.3010] are performed in the management plane: performance management; fault management; configuration management; accounting management and security management”.
The user plane or transport plane is the functional plane used to transport data from a user to another user, or from a network to another network. In the last case, the user plane can carry data from a management plane or a control plane for the destination network.
