A method includes storing, by one or more computer processors, a plurality of blocks in a queue, wherein each block includes at least one received message, and wherein each block is associated with a time that the block was stored in the queue. The method further includes designating, by the one or more computer processors, as inactive one or more blocks having associated storage times that are older than a first time. The method further includes reading, by the one or more computer processors, messages from inactive blocks until a second time that is older than the first time. The method further includes deleting, by the one or more computer processors, one or more inactive blocks from the queue having associated storage times that are older than the second time.

A method for configuring an adaptable circuit breaker chain in a microservices architecture includes transmitting a request from an upstream service to a target one of the services and receiving in a circuit breaker of the upstream service a response from a circuit breaker of the target indicating an inability to provide a response to the transmitted request and including meta-data describing an attempt by the circuit breaker of the target to receive a response from the downstream service to an underlying request of the target necessary to provide a response to the request transmitted by the upstream service. Finally, on condition that the meta-data indicates a delay by the circuit breaker of the target incurred in receiving a response to the underlying request, the method includes changing a pattern of delay imposed by the circuit breaker of the upstream service from a default pattern of delay.

A peer to peer dynamic network acceleration method and apparatus provide enhanced communications directly between two or more enhanced devices, such as enhanced clients. The enhanced clients may comprise a front-end, a back-end, or both. In general, the front-end and back-end of the enhanced clients work in concert to translate data into an enhanced protocol for communication between the enhanced clients. The enhanced protocol may provide acceleration, security, error correction, and other benefits. Data from various applications may be seamlessly translated between a first protocol and the enhanced protocol, such that the applications need not be modified to use the enhanced protocol. The enhanced clients may automatically detect one another to establish an enhanced communications channel automatically.

A filter or bridge device allows CAN-FD modules to communicate on a communication bus having classic CAN modules without generating error modules by sensing for CAN-FD frames. In response to detecting a CAN-FD frame, the filter or bridge device sends a mimic classic CAN message or frame instead of the original CAN-FD frame to classic CAN modules. An additional feature may include the filter or bridge device adding bits such as CAN overload frames onto the CAN-FD frame, mimicked classic CAN frame, or both to have the two messages end at about a same time to avoid timing errors when the modules begin to send new message frames.

Disclosed is a downlink (DL) multi-user (MU) transmission method of an AP device in a wireless local area network (WLAN) system including generating a DL MU physical protocol data unit (PPDU) including a physical preamble and a data field, the data field including at least one MAC protocol data unit (MPDU), the at least one MPDU including a MAC header and a MAC frame body, and the MAC header including ACK indication information for uplink (UL) MU transmission of an ACK frame as a response to data transmitted through the data field, and transmitting the DL MU PPDU.

A system and method of a communication device including a port configured to receive a plurality of binary data streams having a binary header and a binary body. The device includes a memory storing a first message structure description of the binary header and the binary body, and a second message structure description of a metadata construct of the message. The device includes a processor configured to parse a received binary data stream using the first message structure description to determine the binary header and the binary body. The processor parses the binary body using the second message structure description to determine the one or more groups of description values forming the metadata construct. The processor uses a portion of the determined description values of the metadata construct to determine the one or more groups of data values of the message construct.

Provided are a transmitting apparatus, a receiving apparatus and controlling methods thereof. The transmitting apparatus includes: at least one processor configured to implement a packet generator which generates a packet including a header and a payload based on a plurality of input packets; and a signal processor which signal-processes the generated packet, and a transmitter configured to transmit the signal-processed packet. A base field included in the header includes a first field set to a first value representing that the base field is a first length or a second value representing that the base field is a second length.

A method for communication between at least two computing facilities of a medical imaging facility via a single communication line is disclosed. In the method, communication information assigned to different communication types received in each case via a dedicated data input is merged to form data structures of a defined size to be transmitted via the communication line. The data structures are transmitted cyclically via the communication line with an interval of one cycle time and communication information of the different communication types is extracted from data structures received via the communication line and output at data outputs assigned to the respective communication types. The communication types include a first packet-oriented communication type and a second isochronous communication type corresponding to isochronous direct channel communication.

Use of a preamble conforming to a second protocol to which a preamble field conforming to a first protocol, different from the second one, is added, such as a protocol for accessing a mobile network deployed in an unlicensed band common to the second protocol, for any frame transmitted with a data field conforming to this first protocol.

Methods and devices are provided for executing a data transfer based on one or more data transfer definitions. A signal representing a data transfer request is received from a first computing device. The data transfer request includes at least an identifier defining what is requested to be transferred. A notification of the data transfer request is sent to a second computing device. An interface including a plurality of interface elements for providing one or more data transfer definitions is sent to the second computing device. The interface includes at least one interface element that is pre-populated based on the data transfer request, and at least one interface element providing an option to define a time of day for a data transfer. The one or more data transfer definitions are received from the second computing device and the data transfer is executed based on the one or more data transfer definitions.
