Network system, station-side apparatus, and method of controlling communications

摘要

An aspect of this invention is a network system including subscriber apparatuses and a station-side apparatus for communicating with the subscriber apparatuses. The station-side apparatus communicates with the subscriber apparatuses using wavelengths. The station-side apparatus determines a wavelength to be used by each of at least one subscriber apparatus of the subscriber apparatuses based on effective transmission rates used by the subscriber apparatuses in communications with the station-side apparatus.

主权项

1. A network system comprising:
a plurality of subscriber apparatuses; and a station-side apparatus which communicates with the subscriber apparatuses using wavelengths, wherein the station-side apparatus acquires code rates to be used in error correction control performed in communications between the subscriber apparatuses and the station-side apparatus, wherein the station-side apparatus calculates effective transmission rates of the subscriber apparatuses based on the acquired code rates, and wherein the station-side apparatus determines which of the wavelengths are to be used by each of the subscriber apparatuses based on average effective transmission bandwidths which are calculated based on the effective transmission rates of the subscriber apparatuses using the respective wavelengths in communications.
