BANDWIDTH ADJUSTMENT METHOD AND DEVICE

摘要

The present invention relates to a technical field of an optical communication, and disclosed is a bandwidth adjustment method, applied in an optical transport network (OTN). The method comprises: acquiring a bandwidth of a current service to be transmitted; if a bandwidth difference between the bandwidth of the current service to be transmitted and a current bandwidth of a transmission unit exists, determining a number n of logic tributary signals to be adjusted according to the bandwidth difference; determining a number m of optical tributary signals to be adjusted according to a correspondence of a preset number between the logic tributary signals and the optical tributary signals; and adjusting the numbers of a current photonics carrier, the current optical tributary signal, and the logic tributary signal according to the determined number n of logic tributary signals to be adjusted and the number m of optical tributary signals to be adjusted.
