摘要： The invention provides a control layer for an Optical Burst Switch (OBS) system, said system comprising at least one stage configured with a closed optical burst switch addressing scheme and one or more ports for sending or receiving data packets. The control layer comprises a control addressing scheme independent of the closed optical addressing scheme and means to provide interconnectivity for each port with every other port. In one embodiment there is provided a closed optical burst switch ring network. The control layer encapsulates or maps the optical data at a port into an independent packet format and passes the independent packet format into a queuing system for transmission by the optical burst switch ring network to a destination port.

摘要： The invention relates to a system and method of dispersion measurement in an optical fibre network. The invention provides means for transmitting from a transmitting node, using a single tunable laser transmitter, two consecutive bursts of data at different wavelengths λ1 and λ2 to a receiver node, wherein each burst of data comprises a unique sequence of amplitude modulated data, and wherein the two sequences are injected with a fixed known delay. The delay between the two consecutive bursts of data is maintained by selective switching of the tunable laser, such that clock recovery circuitry at the receiver node remains locked during the delay between the two bursts. The dispersion measurements method of the present invention is based on walk off and bit position detection between two wavelengths suitable for fast optical burst switching network is described. This method does not require an operator, extra equipment, or traffic interruption on the network.
