Abstract: To address the need to excite lasers at a high frequency while minimizing electrical parasitic components, the present invention embraces a system and method of exciting a laser using a direct injection of an electron beam. The system may include a low voltage electron emission device made of one or more electron sources. When the device is activated, an electrical field is applied to the tip of each electron source, causing the electron source to emit a stream of electrons. The electrons are directed into a VCSEL, causing it to emit an optical signal. In another aspect, a system for random number generation is provided. The system may also include a processor that receives a measurement of an initial random value, executes an algorithm, where at least one input of the algorithm is the initial random value, and determines a final random value.

Abstract: An apparatus includes a processor and split-read control circuitry (SRCC). The processor is to issue a set of one or more split-read requests for loading one or more data values to one or more respective local registers of the processor. The SRCC is to receive the set of one or more split-read requests, to read the one or more data values on behalf of the processor, and to write the data values into the one or more respective local registers. The processor and the SRCC are to coordinate a status of the split-read requests via a split-read-status indication.

Abstract: A network element includes multiple ports and a packet classifier. The packet classifier is configured to receive rules and Rule Patterns (RPs), each RP corresponding to a subset of the rules and specifies positions of unmasked packet-header bits to be matched by the rules in the subset, to store in a RAM a grouping of the RPs into Extended RPs (ERPs), each ERP defining a superset of the unmasked bits in the RPs associated therewith, to receive packets and match each packet to one or more of the rules by accessing the ERPs in the RAM, to determine counter values, each counter value corresponding to a respective RP and is indicative of a number of the received packets that match the RP, and to adaptively modify grouping of the RPs into the ERPs depending on the counter values.

Abstract: Systems and techniques for securing network communications are described. A network device comprises a network interface and at least one accelerator. The network device inspects obtained data using the accelerator. The network device determines, based on the inspection, that the data is indicative of a violation of a security policy, and generates a response to the violation.

Abstract: A signal processing method includes receiving a digital signal including a sequence of samples. For each sample among at least some of the samples, a neighbor-based estimate is calculated over (i) one or more samples that precede the sample in the sequence and (ii) one or more samples that succeed the sample in the sequence, and an error value, indicative of a deviation of the neighbor-based estimate from an actual value of the sample, is calculating. An impairment in the digital signal is estimated based on a plurality of error values calculated for a plurality of the samples.

Abstract: A pluggable network interface device is provided comprising a split-shell housing having a shielded side portion that protects a side of a circuit substrate disposed in the split-shell housing. The split-shell housing comprises a first shell portion that covers a first side of the circuit substrate and a second shell portion that covers a second side of the circuit substrate that is arranged opposite the first side. The shielded side portion is inset from a width of the split-shell housing and offset a distance from an electrical interconnection end of the circuit substrate. The shielded side portion is arranged at least partially in a notch of the circuit substrate disposed at the electrical interconnection end of the circuit substrate.

Abstract: Optical communication modules and associated methods and computer program products for performing network communication security are provided. An example optical module includes a substrate, a first optoelectronic component supported by the substrate configured for operation with optical signals having a first wavelength, and a second optoelectronic component supported by the substrate configured for operation with optical signals having a second wavelength. The module further includes an optical communication medium defining a first end in optical communication with the first optoelectronic component and the second optoelectronic component and a second end. The module also includes security circuitry operably connected with the first optoelectronic component and the second optoelectronic component. The security circuitry determines the presence of a noncompliant component coupled with the optical communication medium at the second end based upon operation of the second optoelectronic component.

Abstract: A method for checking electrical rules in a design of a circuit including transistors connected by nodes, includes defining a hierarchical database including (i) a root representing the circuit, and (ii) instances of context-cells representing design entities and including node-ports that connect the design entities. Electrical properties of the node-ports are propagated from the root through the node-ports to at least a portion of the context-cells. The electrical properties, which were propagated from the root, are propagated from one or more of the context-cells to one or more peer context-cells. An electrical rule violation in at least one of the context-cells is identified based on the propagated electrical properties.
