Claim of US Patent No. 9,473,242

1. A method of operating a connection-oriented first communications network having a plurality of first network elements in
which connections across the first network elements are determined by a connection computing apparatus, the connection-oriented
first communications network being connectable to a second communications network by a network element, the second communications
network having a plurality of second network elements, the method being performed to establish a connection across the connection-oriented
first communications network in response to a connection request from the second communications network, the method comprising
the steps of:
the connection computing apparatus receiving from the network element information relating to the connection request which
the network element received from the second communications network;

the connection computing apparatus sending to the network element a signal indicative of a status of the connection; and
clearing down any intermediate connections established in relation to the connection request if setting of the connection
failed.
