摘要： A reconfigurable AGC loop design for an optical amplifier with a software provisional switch in the AGC loop inside the optical amplifier is disclosed. On the input side, there is a 1×m switch for switching a first input to the input of an optical amplifier, or to route other external pins to the optical amplifier. On the output side, there is a 1×n switch for switching a first output to the output of an optical amplifier, or to route other external pins to the optical amplifier. The AGC loop inside an optical amplifier is available to operate with other external signals. This reconfigurability unleashes the AGC loop capability that is traditionally confined to individual optical amplifier, provides flexibility, and greatly simplifies the design of optical node.

摘要： A self-adjusting optical add-drop multiplexer monitors the power in a drop signal and attenuates the power in an add signal to match the power in express WDM channels (signals). When used in a fiber network, and more particularly, in a metro network, the deleterious effects of optical amplification are reduced. Power attenuation is also used in an optical switching assembly particularly useful in two-fiber ring network. The optical switching assembly monitors drop channels from the two rings of the network and attenuates the add channel(s) accordingly. An optical switch operates to direct the drop signal from one of the two rings to a receiver in accordance with a control signal based on the monitored drop channels. The self-adjusting optical add-drop multiplexer also monitors the power in the drop signals and issues an alarm if the drop signal is of a power level above or below predetermined levels.

摘要： A distributed system checker may check a distributed system against events to detect bugs in the distributed system. The events may include machines crashes, network partitions, and packet losses, for example. The distributed system checker may check a distributed system that can have multiple threads and multiple processes running on multiple nodes. To obtain control over a distributed system, a distributed system checker may insert an interposition layer between a process and the operating system on each node.

摘要： A method for bounded model checking of arbitrary Linear Time Logic temporal properties. The method comprises translating properties associated with temporal operators F(p), G(p), U(p, q) and X(p) into property checking schemas comprising Boolean satisfiability checks, wherein F represents an eventuality operator, G represents a globally operator, U represents an until operator and X represents a next-time operator. The overall property is checked in a customized manner by repeated invocations of the property checking schemas for F(p), G(p), U(p, q), X(p) operators and standard handling of atomic propositions and Boolean operators.

摘要： Quantified Boolean formula (QBF) techniques are used in determining QBF satisfiability. A QBF is broken into component parts that are analyzable by a satisfiability (SAT) solver. Each component is then independently, and perhaps in parallel, analyzed for satisfiability. If a component is unsatisfiable, then it is determined that the QBF is unsatisfiable, and the analysis is stopped. If a component is satisfiable, then an assignment corresponding to the satisfiable component is noted. If a component is satisfiable, then it is appended to another untested component to provide a combination component, and the satisfiability of the combination component is analyzed. Such appending and analysis is repeated until the QBF is completed and determined to be satisfiable or determined to be unsatisfiable.
