Abstract
The method is used in a switching network over which data packets are transferred and which includes a plurality of switching nodes with switching node terminations (SNT) and associates in each one of the switching node terminations (SNT) internal header information (IHI) included in an internal data packet received by the switching node termination and identifying an internal connection within the switching node and ending in the switching node termination, to external header information (EHI) included in an external data packet and identifying an outgoing external connection external to the switching node and originating from the switching node termination. The internal header information (IHI) includes a connection reference number (CRN) and a transfer type is associated to the internal connection. The method comprises three steps: PA1 a. determining the transfer type; PA1 b. associating to the connection reference number (CRN) and based on the transfer type a transfer type independent connection reference number (TTI-CRN) which is locally allocated by the switching node termination (SNT); and PA1 c. associating to the transfer type independent connection reference number (TTI-C…
