A technique efficiently captures information required to create a filter used by switching nodes of a heterogeneous network to implement transmission priority routing of data traffic over a connection network between end nodes of the network. A bounded time interval, i.e., a time window, is established during which a first switching node monitors the traffic over the network to capture portions of the required information contained in a defined data packet. Monitoring of data traffic during the time window is triggered by a predictable event, the occurrence of which is communicated to the first switching node by a hybrid node of the network. In addition to providing this "triggering" communication, the hybrid node also provides the first switching node with the remaining portion of the required information.

[ What is claimed is:] [1.] A method for efficiently acquiring information used by first and second switching nodes of a heterogeneous network to implement transmission priority (TP) routing of data traffic over a connection network between end nodes of the network, the method comprising the steps of:establishing a bounded time interval during which a first switching node examines the data traffic over the network;triggering monitoring the data traffic during the bounded time interval for a defined data packet in response to a predetermined triggering event; andcapturing a portion of the information from the defined data packet at the first switching node during the bounded time interval, the captured portion of information used to implement TP routing;wherein the predetermined triggering event is a request issued by one node of the network to a second node of the network for the second node to compute a route through the network between the one node and a third node of the network.
