A method and system for determining the connections of a communication path are provided. Starting from a one connection point, the identity of the connection point that precedes the one connection point in the direction in which the path was established is requested from the network element on which the one connection point is located. This may be repeated until a root endpoint is reached. Some embodiments are implemented for P2MP SPVC (Soft Permanent Virtual Connection) communications.
