摘要： A method for measuring asymmetry in propagation delay of first and second links which connect a first node to a second node of a communication network. The method comprises measuring (101) a round trip delay of the first link. The round trip delay can be measured by transmitting (102) a test signal from the first node to the second node over the first link and receiving a reply to the test signal from the second node over the first link. The method further comprises measuring (105) a round trip delay of the second link. The round trip delay can be measured by transmitting (106) a test signal to the second node over the second link and receiving a reply to the test signal from the second node over the second link. A difference in the propagation delay of the first link with respect to the second link is determined (109) using the measured round trip delays of the first link and the second link.

摘要： A method for optimisation of the number and location of regenerative or non-regenerative repeaters in a WDM link made up of N spans connected in a succession of N−1 intermediate sites to form link sections separated by sites containing regenerative repeaters, comprises a step for defining the number of regenerative repeaters needed and giving them a first location. Said step comprises the phases of defining targets OSNRs (VOSNRT) as a function of the number of spans and the type of fibre used in the spans, and defining a possible section between an initial site and a final site, appraising a metric function VM for said possible section obtained as a function of the difference between the OSNR (VOSNR) at the final end of the first span of said possible section and the corresponding target OSNR (VOSNRT) given by the number of spans in said possible section. If the appraised metric function VM satisfies an established quality parameter, add to the possible section the following span in the link and again appraise the metric function for said new possible section obtained as a function of the difference between the OSNR (VOSNR) at the final end of the first span of the possible section and the corresponding target OSNR (VOSNRT) with the new number of spans in the possible section. Said steps are repeated iteratively while adding spans to the possible section until the metric function VM no longer satisfies the quality parameter and one returns at the end site preceding the last span added and positions a regenerator in said site. The procedure is repeated until the end of the new section is identified or to exhaustion of the spans of the link.
