WAVELENGTH AND BANDWIDTH ALLOCATION METHOD

摘要

A wavelength and bandwidth allocation method which includes in order a wavelength determination step S4 of determining a plurality of wavelengths of an uplink signal from each ONU to OLT to guarantee a guaranteed bandwidth corresponding to a subscription service class of each ONU and a reference bandwidth distribution step S5 of distributing, as reference bandwidths, all bandwidths of the plurality of wavelengths determined in the wavelength determination step S4 to each ONU according to the subscription service class of each ONU and making the reference bandwidths of ONUs whose subscription service classes are the same be the same.

1. A wavelength and bandwidth allocation method, which, in a passive optical communication network in which a plurality of optical network units (ONUs) are connected to one optical line terminal (OLT), each of the ONUs transmits an uplink signal of any one of a plurality of previously provided wavelengths to the OLT, and the OLT receives the uplink signals of all the previously provided wavelengths from each of the ONUs, is performed by the OLT, the method comprising in order:
a wavelength determination step of determining a plurality of wavelengths of the uplink signal from each of the ONUs to the OLT to guarantee a guaranteed bandwidth corresponding to a subscription service class of each of the ONUs; and a reference bandwidth distribution step of distributing, as reference bandwidths, all bandwidths of the plurality of wavelengths determined in the wavelength determination step to each of the ONUs according to the subscription service class of each of the ONUs and making the reference bandwidths of the respective ONUs whose subscription service classes are the same be the same.
