摘要： An optoelectronic timing system includes an optical timing compensation system in which optical pulses developed by a semiconductor laser are advanced or retarded based upon an expected arrival time. The pulses are directed into a number of time-quantifiable optical paths. Time quantification for a pulse is based upon the time required for a pulse to travel a particular length at the speed of light. Pulses are directed into an advancing path or a retarding path by optical switches which compare an expected arrival time of a new pulse to an expected arrival time based on a previous pulse. The optical compensation system is incorporated into a precision timing device in which multiple optical paths, having decreasing lengths in a defined pattern, are arranged in serial fashion so as to have each subsequent path of the series represent a travel time one order of magnitude different than a travel time of an adjacent path. Timing signals are developed by coupling an optical detector to each of the multiple optical paths.

摘要： An optical network, which includes edge and switching nodes, optically communicate information formatted into statistically multiplexed control and data bursts and/or metadata. Control bursts are transmitted prior to the data bursts to configure optical switches in selected switching nodes so that the data bursts do not require O-E-O conversion. Each edge node consists of an adaptive PBS medium-access layer (MAC) component in order to achieve the transmission throughput improvement. The adaptive PBS MAC component enables the PBS data burst size to adapt to the TCP flow, allowing the PBS data burst to be transmitted immediately for the TCP flow experiencing TCP slow start. It performs a nulldeepnull packet inspection of control packets coming back to the data source from the destination PBS network edge node to detect packet losses.

摘要： A method and apparatus for a network database in an optical network. According to one embodiment of the invention, a wavelength division multiplexing optical network includes optical network devices interconnected by links. These optical network devices propagate along the links connectivity request messages, initiated at each of the optical network devices acting as an access node, to discover possible end to end paths that meet a set of zero or more connectivity constraints, where an end to end path is a series of two or more of the optical network devices connected by links on which a set of wavelengths is available for establishing a lightpath. In addition, the optical network devices acting as access nodes each include a database representing available paths with costs from that access node to reachable destination nodes, where each of the paths has associated with it in the database the wavelengths available on that path.

摘要： An intelligent photonic burst switching (PBS) module for use in a WDM optical switching network includes optical multiplexers and de-multiplexers, an optical receiver array, an optical transmitter array, a PBS fabric, and a control interface unit. The PBS module includes optical buffering in a form of tunable wavelength converters (TWCs) and variable time-delay optical circuits. The PBS module routes the received optical burst labels and network management control labels to the controller and optical burst data in a plurality of input lines, respectively. The optical output lines provide propagation paths for a plurality of TDM channels. More specifically, the controller processes the control signal and, responsive thereto, causes the PBS to route at least a portion of the data signal to one of the TDM channels. When the desired TDM channel is not available, the controller causes a TWC to effectively change the wavelength of at least a portion of the data signal.

摘要： A wavelength exerciser is used for evaluating connections in an agile network. The exerciser operates at some or all switching nodes of the network, by first detecting the paths available between the respective node and all remaining nodes. For each available path, the exerciser selects some or all wavelengths that can carry the traffic all the way along the path. It can operate both during SLAT and/or during network normal operation. When the network carries live traffic, the wavelengths used on the test connections are wavelengths that are not used at the respective moment by the user traffic. The exerciser verifies the switch architecture and the access architecture, and also collects information about the performance of all paths, so as to speed-up the path-connection matching process and to increase the chances of successfully establishing the connection along the selected path.
