An optical internet router apparatus uses optical tags to send and receive command and response messages between routers of an optical network for establishing, maintaining or changing a packet data connection over the network between a source router and a destination router. The optical router comprises (1) optical tag apparatus for reading a message and writing a message modulated on one or more wavelengths which are used for communicating with another router of a network connection, the control message being modulated onto the one or more wavelengths using a secondary modulation scheme which is different from a primary modulation used to modulate packet data; and (2) a controller responsive to a received read message for controlling a network connection at this router, and for generating a network control message to be written by the optical tag apparatus, the generated message controlling a network connection to said another router.
