17 * PCEP Session represents the finite state machine in PCEP, including timers and its purpose is to create a PCEP
18 * connection between PCE/PCC. Session is automatically started, when TCP connection is created, but can be stopped
19 * manually. If the session is up, it has to redirect messages to/from user. Handles also malformed messages and unknown
22 public interface PCEPSession extends PCEPSessionState, AutoCloseable {
25 * Sends message from user to PCE/PCC. If the user sends an Open Message, the session returns an error (open message
26 * is only allowed, when a PCEP handshake is in progress). Close message will close the session and free all the

30 * @return Future promise which will be succeed when the message is enqueued in the socket.
