Method, device and system for establishing a so-called Pseudo-circuit

A terminal node (220), configured to: receive (520) a control message including a tag Pseudo-circuit, PW (Label 3), class information Forwarding Equivalence, FEC, and routing information, wherein routing information comprises identification information and additional identification information being identification information an identification information of a switching node (215) and being identification information additional identification information of a further switching node (205 ), while additional identifying information is information identifying following identification information; constructing (530) a message including additional control additional PW label (label 4), additional FEC information and the routing information; send (530) the message additional control to the switching node (215).
