A wireless communication unit is arranged to communicate with one or more wireless mobile communication units. The wireless communication unit comprises: a cellular receiver arranged to receive content from a network server using a conventional client server mechanism; a processor operably coupled to the cellular receiver and configured to convert the received content into a bundle format that can be transmitted into a delay tolerant network; at least one memory operably coupled to the processor and configured to store the bundle formatted content; and at least one short-range wireless circuit operably coupled to the at least one memory and configured to extract the bundle formatted content from the at least one memory and transmit the extracted bundle formatted content to at least one wireless mobile communication unit using a short-range wireless communication technology.

A method manages data traffic in a vehicle controller area network having a plurality of functional modules. To that end, the method and apparatus passively receive data messages transmitted across the controller area network. The data messages are formatted in one of a plurality of proprietary protocols. Next, the method determines the protocol of the data messages. The determined protocol is one of the plurality of proprietary protocols. After determining the protocol, protocol logic translates the data messages (transmitted across the controller area network) from the determined protocol to a given protocol. The protocol logic is configured to translate the data messages from any of the plurality of proprietary protocols into the given protocol. The method then transmits the data messages, in the given protocol, onto the controller area network for use by at least one of the functional modules.

Enhanced MAC-es PDUs are created by concatenating enhanced MAC-es service data units (SDUs) based on higher layer PDUs and segments thereof, where segmentation information is included in the enhanced MAC-es headers. An enhanced MAC-e header is generated for each enhanced MAC-es PDU to describe information about the enhanced MAC-es PDU. An enhanced MAC-e PDU is created by concatenating enhanced MAC-es PDUs and enhanced MAC-e headers. An enhanced MAC-es header may include a Transmit Sequence Number (TSN) field, a Segmentation Description (SD) field, length (L) fields to indicate the length of each enhanced MAC-es SDU and/or logical channel indicator (LCH-ID) fields. An enhanced MAC-e header may include one or more logical channel indicator (LCH-ID) fields for corresponding enhanced MAC-es PDUs or MAC-s SDUs and length (L) fields.

This application discloses an electronic control unit coupled to a bus in a vehicle communication network. The electronic control unit includes a processing system configured to generate an instruction including an identifier of a type of signal exchanged through a vehicle communication network and including a command associated with exchange of a signal value corresponding to the type of the signal. The electronic control unit includes a communication circuitry configured to identify, based on the type of the signal in the instruction, a packet having a section allocated for the signal value corresponding to the type of the signal. The communication circuitry also can perform packet operations on the section of the packet allocated for the signal value based, at least in part, on the command included in the instruction. The packet operations can include packing the signal value into the packet or extracting the signal value from the packet.

A switch for transmitting digital data in the form of frames, each frame having an identification field and being of a first type conforming to an ARINC 664 P7 type protocol or of a second type conforming to an IEEE 802 type protocol. The switch comprising a plurality of input ports, a plurality of output ports, and a configuration table comprising for each identification value of the transmission parameters of the frames having this identification value.

The switch is able to switch each frame between an input port and at least one output port exclusively on the basis of the transmission parameters corresponding to the identification value of this frame in the configuration table, independently of the type of this frame.

A system for processing reading records collected from a resource distribution network and converting IEC reading type codes is provided. For example, a meter data management system obtains meter reading records that are collected from meter nodes deployed in a resource distribution network. Each of the meter nodes is configured to measure characteristics of resource consumption at a location associated with the meter node, and each of the meter reading records includes a reading value of the resource consumption and an IEC reading type code identifying a type of the reading value. The meter data management system processes the meter reading records by converting a reading record from its original IEC reading type code to a common IEC reading type code so that the multiple meter reading records can be aggregated to generate a load profile. Loads associated with the meter nodes can be adjusted based on the generated load file.

A unidirectional transfer protocol allows data to be transmitted from a non-secure network into a secure network. A non-secure gateway may receive data and/or information, intended for the secure network, from one or more devices. The gateway may fragment the data and/or information into smaller chunks and transmit the chunks to a secure gateway via a unidirectional communication channel. The secure gateway may verify the chunks using one or more rules and reassemble the chunks when the data is validated. The reassembled data may be sent across a secure network enclave. The unidirectional transfer protocol may provide a hardware-agnostic solution for transmitting data over a unidirectional communication channel.

An information handling system includes a data handling device and a baseboard management controller (BMC). The data handling device includes a co-processor configured to instantiate a device operating system for the data handling device. The data handling device includes a Management Component Transport Protocol (MCTP) endpoint. The BMC establishes a serial terminal session with the device operating system via the MCTP endpoint.

An information handling system may include a plurality of communication destinations, a communication source, a single-source/multi-destination cable having a plurality of branches, each branch communicatively coupling the communication source to a communication destination respective to such branch, and a logic device communicatively coupled to the communication source and the single-source/multi-destination cable and configured to communicate to each of the plurality of branches both analog source identifying information and digital source identifying information regarding the communication source.

A method implemented by a network element (NE) comprises generating, by a processor, an Internet Protocol version 4 (IPv4) packet comprising an IPv4 header, a plurality of extension headers, and upper layer data, wherein the IPv4 packet indicates a total length of the IPv4 packet and a total length of the plurality of extension headers, indicating, by the processor, a protocol number associated with a first extension header of the plurality of extension headers in a protocol field of the IPv4 header, indicating, by the processor, a protocol used to encode the upper layer data of the IPv4 packet in a last protocol field of a last extension header of the plurality of extension headers, and transmitting, by a transmitter, the IPv4 packet to another NE.
