METHOD FOR MANAGING THE TRANSMISSION OF OPTICAL SIGNALS

摘要

The present invention relates to a method for managing the transmission of optical signals within an optical communication network comprising transparent connections and opaque connections established between the network's nodes, said connections being configured to transmit, at predetermined bit-rates, a set of data packets without any temporal relationship between them wherein the bit-rate of a transparent connection is modified as a function of the quality of said transparent connection's signal within the destination node, said modification of the bit-rate comprising the following steps: - the switching of all of the data packets transmitted by the transparent connection at a first bit-rate to an opaque connection with the same bit-rate, - the changing of the transparent connection's bit-rate from a first bit-rate to a second bit-rate, - the switching of at least some of all the data packets transmitted by the opaque connection back to the transparent connection at the second bit-rate.
