Abstract
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.
