Abstract: A system and method for selecting a resource from among a plurality of resources. A total range of numbers is divided into a plurality of sub-ranges, each associated with a respective one of the resources. An indexing number, e.g., a random number, is generated and, when it falls within the total range of numbers, the resource associated with the sub-range into which the indexing number falls is selected. When the indexing number falls outside of the total range, a resource associated with the difference between the indexing number and the greatest number in the total range is selected.

Abstract: An optoelectronic switch for switching data from a source external client device to a destination external client device, the optoelectronic switch includes: an array of client-side transceivers, each having an array of client-facing optical ports to connect to an external client device, and an array of leaf-facing electrical ports; an array of leaf switches, each including an array of client-side electrical ports and an array of fabric-side electrical ports; a first electrical interconnecting region providing electrical connections between the leaf-facing electrical ports of the client-side transceivers and the client-side electrical ports of the leaf switches, an array of fabric-side transceivers, each having an array of leaf-facing electrical ports, and an array of fabric-facing optical ports; a second electrical interconnecting region providing electrical connections between the fabric-side electrical ports of the leaf switches and the leaf-facing electrical ports of the fabric-side transceivers; an array of spine switches, each including an array of fabric-facing optical ports; and an optical fabric providing connections between the fabric-facing optical ports of the fabric-side transceivers and the fabric-facing optical ports of the spine switches.

Abstract: A system and method for measuring propagation delays and other delays in an optical switching system. A transmitter is connected, through a circuit switch, to a receiver. To measure the propagation delay between the transmitter and the receiver, the transmitter sends one or more time-tagged ranging messages and the receiver calculates a propagation delay from the difference between the time of receipt and the time of transmission. In another embodiment, a time delay between message transmission and transition of a CDR of the receiver to a fast acquisition mode is adjusted, by trial and error, to find a range of such time delays for which transmission is successful. A time delay between the transmitter and the switch is measured by establishing or breaking the connection and determining, for various tentative time delay values, whether transmission succeeds.

Abstract: A system and method for line coding of data. A serial transmitter includes a forward error correction encoding circuit followed by a bit conditioning circuit. The bit conditioning circuit counts the lengths of runs of consecutive identical digits and, when the count reaches a threshold, flips a bit. A serial receiver receives the data from the serial transmitter. The serial receiver includes a forward error correction decoding circuit, which re-flips bits flipped by the bit conditioning circuit of the serial transmitter.
