Patent ID: 8897638

Claim:
An optical packet switching system, comprising: an optical packet switching apparatus configured to extract routing information from an inputted optical packet signal and configured to switch a route of the packet signal; an optical packet transmitting apparatus configured to generate an optical packet signal by adding the routing information to a received client signal and configured to send out the generated optical packet signal to the optical packet switching apparatus; an optical packet receiving apparatus configured to receive the optical packet signal sent out from the optical packet switching apparatus, the optical packet transmitting apparatus including: a packet generator configured to generate a packet signal by adding the routing information to the received client signal; a packet quality information adding unit configured to add packet quality information, by which to detect error occurrence in the packet signal, to the generated packet signal; and an electrical-to-optical converter configured to convert the packet signal, to which the packet quality information has been added, into the optical packet signal and configured to send out the optical packet signal; a first converter configured to convert the inputted packet signal into a plurality of divided packet signals, the first converter being provided subsequent to the packet quality information adding unit; a plurality of the electrical-to-optical converters provided subsequent to the first converter; and a wavelength multiplexing unit configured to multiplex optical packet signals of a plurality of wavelengths outputted from the plurality of the electrical-to-optical converters, and the optical packet receiving apparatus including: an optical-to-electrical converter configured to convert the received optical packet signal into an electrical packet signal; and a packet quality detector configured to detect error occurrence in the packet signal, based on the packet quality information added to the packet signal, and a wavelength division unit configured to demultiplex the received wavelength-multiplexed optical packet signal into optical packets of a plurality of wavelengths; and a plurality of the optical-to-electrical converters provided subsequent to the wavelength division unit; and a second converter configured to convert the plurality of divided packet signals from the plurality of the electrical-to-optical converters into a serial packet signal, the second converter being provided anterior to the packet quality detector.
