The present invention provides improved methods and systems to build an integrated IP network in which high-quality services such as voice and best-effort data services can be provided with higher reliability and lower cost. A new type of router, called a PACS router, is disclosed in which the user terminals, computer servers, access routers and other service terminals are connected to the integrated router. A PACS router includes a packet-switching fabric and a circuit-switching fabric interconnected by channelized high-speed links. The PACS router creates and uses two types of channels within channelized high-speed links, which in turn are transported from one router to another via SONET network links. The channels are labeled as either packet-channel or circuit-channel according to the usage of these channels. High-quality services are mapped into a circuit-channel at the service originating router and routed through the circuit-switching fabrics in the routers. The best-effort services, on the other hand, are mapped into a packet-channel, which is terminated in each PACS router where packets from packet-channels are extracted and routed hop-by-hop according to the packet destination header address. A network built with PACS routers uses signaling and routing protocols to segregate traffic into different classes and route them using circuit-channels and packet-channels depending on quality of service requirements. Routing high-quality service over circuit-channels eliminates routing delay typically incurred in packet-switching fabrics, enhances reliability from software malfunction in the router since existing connection at circuit-switching fabric does not depend on software control and enhances network scalability by not having to terminate all traffic into packet-switching fabrics in every PACS router. The circuit-switching fabrics in the PACS routers also provide further immunity by fast rerouting of failed circuits via alternate routes when a network fault is detected.

A software application that is able to manage a collection of robot repairing resources can be used to assist technicians in repairing and solving hardware or software malfunctions within an electro-mechanical robot. The software application is able to simultaneous monitor multiple different electro-mechanical robots by receiving diagnostic information from them. The software application can identify a malfunction within one of the electro-mechanical robots by comparing its diagnostic information against a set of robot repair manuals. The software application will then select an optimal AI algorithm that has the best chance of repairing the hardware or software malfunction. The software application continues by implementing the optimal AI algorithm with a set of cloud accessible robot repairing applications, a technician's intervention, or a combination thereof.

A system and process that involve a digital computer storage comprising block locations having physical block addresses and logical block addresses representing a relational database configuration of cells at logical intersections of sequences of rows and columns that specify a sequence of records and a sequence of attributes. A key attribute is a unique identifier that corresponds to the date/time instance of entry of a selected record into the database system. The arrangement is such that a succession of records corresponds to a succession of date/time instances of entry into the database system. This arrangement facilitates selection of a range of electronic records that is outside a range of electronic records that may be subject to hardware or software malfunction or corruption, facilitates the timed periodic storage and destruction of electronic records pursuant to an archive schedule, and reduces storage fragmentation by which seek time delay is reduced.

A voltage for driving a cooling fan is usually output from a fan voltage control circuit. Whether to cause the fan voltage control circuit to output the drive voltage or not is controlled by a system management utility (software) and a bridge controller (hardware) on the basis of temperature data from a temperature sensor. To provide for the occurrence of a failure in the system management utility or the bridge controller, a temperature comparator monitors the temperature data from the temperature sensor and instructs a fan voltage control circuit to output a drive voltage for the cooling fan in the case where the temperature rises above a given value.

Embodiments are directed to reducing the number of unit tests performed within a system. In one scenario, a computer system accesses a specified version of an application and evaluates that version of the application to identify connections between software features in the application, and to further identify defects in the software features. The computer system also determines a risk level for the software features, which indicates a likelihood of that software feature causing a software malfunction according to the identified connections or defects. The computer system further generates a feature list that includes, for at least some of the features, a corresponding ongoing risk indicator that indicates the determined likelihood of that feature causing the defect or software malfunction, and performs unit tests against the software application for those features that were indicated as sufficiently likely to cause a defect or software malfunction upon installation or upgrade of the application.

ASICs or like fabrication-preprogrammed hardware provide controlled power and recovery signals to a computing system that is made up of commercial, off-the-shelf components—and that has its own conventional hardware and software fault-protection systems, but these are vulnerable to failure due to external and internal events, bugs, human malice and operator error. The computing system preferably includes processors and programming that are diverse in design and source. The hardware infrastructure uses triple modular redundancy to test itself as well as the computing system, and to remove failed elements—powering up and loading data into spares. The hardware is very simplified in design and programs, so that bugs can be thoroughly rooted out. Communications between the protected system and the hardware are protected by very simple circuits with duplex redundancy.

Debugging systems are configured to resolve both memory aliasing conditions in which a write instruction is directed to an unknown destination address, and concurrency conditions in which control flow information is collected for multiple, concurrently executing threads. Recorded state values corresponding to an application's prior execution and control flow information are both obtained.

A system for detecting a communication computer node malfunction by analysis of network traffic output by the network node. Low latency packet computer nodes copy network traffic and transmit it to ananalytics engine, which may use machine learning techniques, including long short-term memory (LSTM) neural networks, to determine a likelihood that the output of one data router in a network is suffering from a software malfunction, hardware malfunction, or network connectivity issue, and preserve overall data quality in the network by causing cessation of traffic by the malfunctioning node of the network.
