摘要： Fault management and providing resilience against failures is an useful for many networks. Protection techniques are used to ensure that networks can continue to provide reliable service and to provide redundant capacity within a network to reroute traffic in presence of a failure. A method or corresponding apparatus according to an example embodiment of the present invention relates to determining availability in a network. The example embodiment calculates availability on a per demand basis for working, protection, and restoration paths among all demands in the network and reports the availability. The reported availability may be used to plan and suggest changes to the network or to recommend addition of equipment to improve the availability of the network while ensuring that service level agreements are satisfied.

摘要： Signals propagating in wavelength division multiplexing (WDM) optical networks suffer from loss, which decreases optical signal-to-noise ratios (OSNRs) and degrades a quality of received transmissions. Present methods of boosting OSNRs involve regeneration using transponders, which scale in complexity with the number of WDM channels. Optical amplifiers may boost signal strength, but amplified spontaneous emission (ASE) noise often reduces OSNR despite increases in signal strength, although changing the amplifier operating settings may reduce emitted ASE noise power. A method or corresponding apparatus in an example embodiment of the present invention provides a planning tool for deploying optical amplifiers in an optical network in a manner that reduces the need for optical regeneration, reducing cost and complexity of the deployed network. In one embodiment, the disclosed planning tool may substitute models of high-gain amplifiers operating at low settings for models of low-gain amplifiers operating at high settings.

摘要： A fluid ejection device includes a fluid chamber, a fluid restriction communicated with the fluid chamber, and a fluid channel communicated with the fluid restriction. The fluid restriction has a fluid restriction parameter defined as (2*W+2*H)*L/(H*W), wherein W is a width of the fluid restriction, H is a height of the fluid restriction, and L is a length of the fluid restriction. As such, the fluid restriction parameter is in a range of 1.5 to 5.75.

摘要： A procedure for recovering a communication network, and a system, apparatus, and computer program that operate in accordance with the procedure. The procedure comprises aggregating network related information. A determination is made, based on the network related information, of whether one or more predetermined failure thresholds have been exceeded, to generate a determining result. The one or more predetermined failure thresholds are based, at least in part, on an aggregation of a predetermined number of failures. A re-provisioning algorithm is executed to re-provision one or more portions of the communication network based on at least one of the network related information and the determining result.
