    摘要： A system and method for determining a minimum pulse width for a digital data stream is described herein. The minimum pulse width is used to infer the data rate for the digital data stream. A measuring cell is used to measure the pulse widths by utilizing RC time constants. The measuring cell comprises a capacitor whose voltage is related to the pulse width. This voltage is then transferred by the measuring cell to a measurement node which determines the minimum pulse width of all the transferred voltages for the plurality of pulses.

    摘要： A method and system for transferring a queue of packets in a router between an inbound controller and an outbound controller is disclosed. The inbound controller is adapted for receiving an inbound packet at an inbound port. In addition, a plurality of inbound queues are provided for the inbound port. An inbound packet is then received at the inbound port. The inbound packet is classified in a selected one of the plurality of inbound queues according to packet sorting criteria. The inbound packet is then stored in the selected one of the plurality of inbound queues. The inbound controller is capable of determining when one of the plurality of inbound queues is ready to be moved to an outbound queue which is capable of storing a multiplicity of inbound queues. The outbound controller is adapted for forwarding packets at an outbound port. At least one outbound queue is provided for the outbound port which is capable of storing a plurality of inbound queues. The outbound controller is capable of receiving a notification to handle an inbound queue storing a plurality of packets. The inbound queue is then transferred to the outbound queue. The outbound controller may then transmit packets stored in the outbound queue. A CPU may control the inbound controller and the outbound controller.

    摘要： In a ring having first and second adjacent nodes, and two fibers carrying information between the first and second nodes, the first fiber carries information in one direction, while the second fiber carries information in another direction. Each fiber includes wavelength capacity allocated to working and protection traffic. The working and protection wavelength capacities in the first fiber are respectively assigned to first and second disjoint sets of wavelengths, while the working and protection wavelength capacities in the second fiber are respectively assigned to the second and first disjoint sets of wavelengths.

    摘要： A system and method for locally determining a fair allocated bandwidth for a network node configured to send and receive packets in an upstream direction and a downstream direction is disclosed. A local allocated bandwidth is allocated for locally generated network packets sent in the downstream direction. A minimum downstream available network bandwidth is determined from information received in the upstream direction. The local allocated bandwidth is adjusted based on the minimum downstream available network bandwidth and the local allocated bandwidth is used to govern whether a class of locally generated network packets are sent in the downstream direction.

    摘要： A hash table addressing mechanism enters multiple, overlaid look-up tables with a hash table address that corresponds to an X-bit index J that includes both bits associated with a V-bit identifier that selects the appropriate overlaid table, and a Y-bit identifier that hashes to an X-bit index I that selects the appropriate location within the selected table. The table includes hash bins with locations that contain Y-bit identifiers that map under the hash function to the same index I. For each addressed location the system compares the stored identifier with only the Y-bit identifier used to produce the index I, to determine which of the table locations is associated with both the Y-bit identifier and the V-bit identifier that were used to produce the hash table address.

    摘要： A port aggregation protocol (PAGP) dynamically aggregates redundant links between two neighboring devices in a computer network through the exchange of aggregation protocol data unit (AGPDU) frames between the two devices. Each AGPDU frame contains a unique identifier corresponding to the device sourcing the frame and a port number corresponding to the port through which the frame is forwarded. The exchange of AGPDU frames and the information contained therein allows the neighboring devices to identify those ports corresponding to the redundant links. Each device then dynamically aggregates its ports corresponding to the redundant links into a logical aggregation port (agport) which appears as a single, high-bandwidth port or interface to other processes executing on the device.
