Zusammenfassung:The invention relates to a method and network for providing an optical fibre wavelength routed network comprising a plurality of nodes on a network ring where each node can drop and add a wavelength, control means to control the wavelength to be transmitted on the network ring, and access means for each node to enable a node to transmit wavelength onto the network ring whereby wavelength collisions with transmit wavelength from other nodes are avoided in the network. The invention describes a network and method having a ring system with a plurality of nodes and an interconnection means to allow information to be communicated between the nodes of the network using packets of data on a wavelength in a novel and efficient manner.
