Abstract

An existing active base logic flow between a master transceiver and a slave transceiver, is selected as reference logic flow wherein is generated a set of concurrent logic flows. The concurrent logic flows are built with successive elementary packets segmenting pairs of command/response. An exchange of pairs of command/response is initialised and continued by the master transceiver on the basis of specific commands. The slave transceiver triggers a segmentation by transmitting specific responses on the reference logic flow.
