| 摘要 |
A method is proposed for setting up a communications path between a first communications sub-network and a second communications sub-network by means of an intermediate communications sub-network in an extended communications network. More specifically, to set up the communications path, said intermediate sub-network comprises at least two tunnel end-points and an input tunnel end-point of said intermediate sub-network which performs the following steps of: receiving, from a tunnel of said input tunnel end-point, a relay activation message to set up said path, said message referring to a local relay involving said input tunnel end-point; determining, from said relay activation message, an output tunnel end-point of said intermediate sub-network involved in the local relay; activating the local relay for a part of said path between said first sub-network and said second sub-network transmitting the relay activation message to said output tunnel end-point.
