Abstract
A Path Computation Client (24) of a node in a network sends a request message (52) to a Path Computation Element (28) of the network for computation of a path, and the Path Computation Element sends a response message (54) comprising information identifying a calculated path. The Path Computation Element also sends a request for feedback on a result of the attempt to set up the connection. The Path Computation Element attempts to set up a connection based on the calculated path, and reports (64) to the Path Computation Element the result of the attempt to set up the connection.
