An apparatus comprising: an input for receiving a stream of data transmission units; a filter configured to identify data transmission units of a first predetermined type based on predefined identifying information and generate a second stream of data transmission units comprising said first stream with at least one data transmission unit filtered out; a protocol module configured to identify, based on second predefined identifying information, and in said second stream at least one data transmission unit of a second predetermined type and add protocol information thereto; and wherein the filter being configured to filter out said at least one data transmission unit provides time in said second stream for the addition of the protocol information; and wherein the apparatus includes a transceiver configured to output signals representative of said data transmission units of the second stream with said protocol information added to a transmission medium.

Apparatus including a transceiver

An apparatus for providing an interface between a first network that operates based on a first protocol and a second network that operates based on a second protocol, includes a receive terminal configured to receive one or more first messages encoded according to the first protocol, the first messages encapsulating a plurality of second messages. The apparatus is configured to extract encapsulated second messages, determine for each of extracted second messages, and based on flow identifying information of each of extracted second messages, a flow to which the extracted second message belongs. The extracted second messages of the flow provide for transmission of the extracted second messages on the second network encoded based on the second protocol with a time spacing there between greater than a predetermined minimum time spacing.

Network interface apparatus

A system for data communication between electronic devices comprises a first electronic device that is a resource-constrained device; and a second electronic device that exchanges data with the first electronic device. One of the first electronic device and the second electronic device generates a message in a data unit frame complying with a protocol stack that includes a Constrained Application Protocol (CoAP) message on a data link layer in the absence of a User Datagram Protocol (UDP) layer.

Data communication using Constrained Application Protocol over local area network

Embodiments of a device and a method for providing data are disclosed. In an embodiment, a device includes a processing system configured to split data of a request into messages by splitting the data based on a node of the data, where the messages fit a supported size, and provide the messages that include the data of the request to a communications interface.

Network node with reconfigurable rule-based routing

Embodiments of a method and device are disclosed. In an embodiment, a method for synchronizing a slave clock in a Time Sensitive Network (TSN) that includes multiple Precision Time Protocol (PTP) clock domains is disclosed. The method involves determining parameters related to multiple PTP clock domains, assigning domain-specific weights to the multiple PTP clock domains based on the determined parameters, generating a control signal for a clock parameter using the domain-specific weights assigned to the multiple PTP clock domains, and adjusting the clock parameter of a slave clock in response to the control signal.

Method and system for merging clocks from multiple precision time protocol (PTP) clock domains

A network switch is disclosed. The network switch includes an input port and an output port. The network switch further includes a rule logic and a memory for storing a configurable counter. The rule logic is configured to inspect a packet received via the input port and attempt to find a rule for the packet and if the rule is found, to reset the counter and process the packet according to a preconfigured follow up action associated with the rule and if the rule is not found, to route the packet according to a default rule. The rule logic is configured to identify the packet for a follow up action based at least on a subset of content of the packet including a header and a payload of the packet. The counter may hold a time value or the number of packets from a same source to a same destination, a number of bytes received from the same source to a same destination, or a user configurable parameter to control the rule validity period.
