Patent ID: 7106698

Claim:
Method for triggering the control plane in an asynchronous connection-oriented transmission network, comprising the following steps initiated at any time on request by a source node: sending from the Control ATM Test Application (CATMTA) of said source node a call setup message for testing the connectivity of a network connection to the Deamon ATM Test Application (DATMTA) of a destination node, and sending back an acknowledgement message from said DATMTA of said destination node to said CATMTA of said source node when the connection has been successfully established between said source node and said destination node; and sending a verification data stream from said CATMTA in said source node to said destination node after receiving said acknowledgement message, and sending back a response data stream from said DATMTA in said destination node to said source node, said response data stream including a count by the destination node of an amount of data in the verification data stream received at the destination node, said response data stream further including a measured time span over which the destination node received the verification data stream, whereby said verification and response data streams are used to check the characteristics of the connection previously established between said source node and said destination node, including determining, by the source node, a bandwidth of the connection using the amount of data and the time span from the response data stream.
