communtation device of the pharmaceutical, a description of arbitrating between applications of the transfer of sets of pharmaceutical, to a node of a communication network is very high flow

摘要

A device (d) data switching (d) comprises the input interfaces (ie1 - iei) receiving the data to transmit, a switching stage (ea) responsible for routing the data received, the output interfaces (is1 - isj) delivering the data are switched through, and of the arbitration means (ma i) controlling the data transfers between the input and output interfaces, in successive time segments, by means of authorization messages corresponding to transfer requests from the input interfaces. Each input interface (ie1 - iei) is designed to deliver for at least one output interface a handover request of a number of sets of data belonging to the same stream. The switching stage (ea) is adapted to switch the applications received. Each output interface (is1 - isj) comprises means for arbitration (ma1 - maj) designed to determine if each transfer request was received may be at least partially satisfied locally for the future time slots, and to deliver for each input interface applicant an authorization message representative of the maximum number of sets of data that it is allowed to be transferred for each of these future time slices.
