Technologies are generally described for using different wavelengths and/or using different frequencies of light to encode each of information data and control data in a beam of light and to use the encoded control data to route the encoded information data through a network. Routing may be effected using optical switches configured with transmissive and reflective properties, which may allow transmission of certain encoded control data and may allow reflection of certain information data, depending upon the routing for the travel of the light through the network.
