Reliable communications using a point to point protocol
This disclosure describes techniques for performing communications between devices using various aspects of Ethernet standards. As further described herein, a protocol is disclosed that may be used for communications between devices, where the communications take place over a physical connection complying with Ethernet standards. Such a protocol may enable reliable and in-order delivery of frames between devices, while following Ethernet physical layer rules, Ethernet symbol encoding, Ethernet lane alignment, and/or Ethernet frame formats.
METHOD AND APPARATUS FOR SIMULTANEOUS PROTOCOL AND PHYSICAL LAYER TESTING
A method, system, and apparatus for simultaneous physical layer and protocol testing is provided that provides for simultaneous test of many layers of the communication stack at the same time, providing further measurement capability and insight into complex phenomena.
Method and system for data transfer on an avionics bus
A method for transmitting a set of conforming data frames in a specialized data network, the method comprising generating a specialized header, providing the specialized header to a data destination, generating a set of conforming data frames, providing at least a subset of the conforming data frames to the data destination, identifying the subset of conforming data frames, and performing processing operations on the stored subset of conforming data frame.
Method for remote vehicle diagnostics and device
A device connector receives a TCP data packet of a diagnostic device in a data TCP communication manner, encapsulates the TCP data packet into a first data packet, and transmits the first data packet to the vehicle connector through remote communication. A vehicle connector converts the first data packet into a TCP diagnostics instruction data packet and transmits the TCP diagnostics instruction data packet to a vehicle. The vehicle connector receives, based on TCP communication, a TCP diagnostics response data packet, encapsulates the TCP diagnostics response data packet into a second data packet, and transmits the second data packet to the device connector through the remote communication. The device connector converts the second data packet into the TCP diagnostics response data packet and transmits the TCP diagnostics response data packet to a diagnostic device. The diagnostic device obtains a diagnostics result and presents the diagnostics result to a user.
Notification of event subsequent to communication failure with security system
Methods and systems for monitoring a premises are described. A server external to the premises may be in communication with a system at the premises. The server may receive status data from the system from one or more interfaces. If a loss of communication occurs on one interface, then the status data may be received via a second interface. The server may determine timing information for status data received via the first interface and for status data received via the second interface. The server may send, based on the timing information, a message to a computing device indicating the loss of communication.
Technique for reliable communication in a cloud robotics system
A technique for providing reliable wireless communication between a robot (104) and a robot controller (102) in a cloud robotics system is disclosed. A method implementation of the technique is performed by a primary connectivity component (106) supporting multipath transmission over a plurality of wireless transmission paths to establish connectivity between the robot (104) and the robot controller (102). The method comprises triggering determining (S402) a robot sensitivity value indicating a degree of operation sensitivity of the robot (104) to a transmission failure between the robot (104) and the robot controller (102), and triggering configuring (S404) use of one or more of the plurality of wireless transmission paths for communication between the robot (104) and the robot controller (102) depending on the determined robot sensitivity value.
Methods and apparatus for a control station
Provided is a control station that may be configured to control and/or monitor various devices, such as, for example, industrial devices. The control station may comprise communication circuitry, a first processor, and a second processor configured to communicate with one or more devices via the communication circuitry. Information from the one or more devices are configured to be processed by at least one of the first processor and the second processor, and at least one of the first processor and the second processor is configured to output the processed information to one or more of: an electronic display of the control station, a display external to the control station, and a server.
METHOD AND SYSTEM FOR COMMUNICATING UNICAST/MULTICAST MESSAGES USING AUTOMATIC DEPENDENT SURVEILLANCE - BROADCAST (ADS-B) PROTOCOL
Methods are described for generating encrypted messages and unicast/multicast transmitting the encrypted messages to one or more aircraft using Automatic Dependent Surveillance-Broadcast (ADS-B) transmission. Corresponding system for communicating messages to an aircraft using ADS-B link is also provided.
Storage-Optimized Data-Atomic Systems and Techniques for Handling Erasures and Errors in Distributed Storage Systems
Described are devices, systems and techniques for implementing atomic memory objects in a multi-writer, multi-reader setting. In an embodiment, the devices, systems and techniques use maximum distance separable (MDS) codes, and may be specifically designed to optimize a total storage cost for a given fault-tolerance requirement. Also described is an embodiment to handle the case where some of the servers can return erroneous coded elements during a read operation.
NETWORK ACCESS NODE VIRTUAL FABRICS CONFIGURED DYNAMICALLY OVER AN UNDERLAY NETWORK
Network access node virtual fabrics configured dynamically over an underlay network are described. A centralized controller, such as a software-defined networking (SDN) controller, of a packet switched network is configured to establish one or more virtual fabrics as overlay networks on top of the physical underlay network of the packet switched network. For example, the SDN controller may define multiple sets of two of more access nodes connected to the packet switched network, and the access nodes of a given one of the sets may use a new data transmission protocol, referred to generally herein as a fabric control protocol (FCP), to dynamically setup tunnels as a virtual fabric over the packet switched network. The FCP tunnels may include all or a subset of the parallel data paths through the packet switched network between the access nodes for a given virtual fabric.
