Abstract
To transfer an optical packet generated from one source communication node system to a destination communication node system without optical-to-electrical or electrical-to-optical conversion in a network having communication node systems connected thereto, the present invention includes: (a) the source communication node system generating a multi-wavelength label by encoding wavelengths; (b) combining the encoded label with a data packet to generate an optical packet, and sending the optical packet to the network; (c) the routing system dividing the optical packet received from the network into a label and data; (d) decoding and analyzing the label; (e) determining the destination communication node system based on the analysis result of the label; and (f) sending the data packet to the destination communication node system.
