Network switch with packet scheduling
InactiveUS7274691B2Guaranteed packet deliveryAlleviates transmission problemData switching by path configurationNetwork connectionsPacket lossPacket scheduling
An apparatus and method for switching data packet flows by assigning schedules to guaranteed delay and bandwidth traffic. Scheduled bandwidth is subtracted from the available bandwidth, and the remaining unscheduled bandwidth is available for standard “best-efforts” packet transmissions, or other guaranteed packet flows. Guaranteed bandwidth is assigned on a schedule basis, and packet flows are assigned schedules which are mutually acceptable to both transmitters and receivers. Flows transmit and expect to receive packets in accordance with their assigned schedules. Schedules are negotiated between packet transmitter applications and packet receiver applications. During scheduled periods, packets sent by the packet transmitter are directly and immediately forwarded to the assigned packet receiver. Other traffic destined for the receiver is placed in a delay queue, and other packets are not transmitted to the packet receiver during the assigned schedule, as long as the transmitter is still sending guaranteed packets.

DWDM channel detection system
ActiveUS6911645B2Control delayRadiation pyrometryWavelength-division multiplex systemsSpectrum analyzerCoherence time
A channel detection system includes an interferometer coupled to a spectrum analyzer to differentiate additive spontaneous emission (ASE) noise from optical channels in a dense wave-division multiplex (DWDM) signal. It is assumed that channels, if present, are centered at frequencies corresponding to a standardized channel grid. The relative delay of the interferometer is chosen to be greater than the coherence time of the ASE noise but less than the coherence time of the channels with the interferometer's free spectral range set to an integer divisor of the channel-to-channel frequency spacing of the grid such that active channels experience a high degree of interference. The phase delay of the interferometer is then adjusted to maximize the interference at each grid-aligned frequency. The spectrum-analyzed outputs are compared (e.g., subtracted from one another and then thresholded) to determine the channels present in the DWDM signal.
