Abstract: 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.

Abstract: A network node comprising:



a message handling module configured to control the sending of messages to one or more output ports of the network node based on a rule set stored at the network node, the rule set comprising one or more rules;
a communication module configured to receive at least one update to the rule set from a controller node, separate from the network node, for changing the rule set;
a supervisor module configured to verify that the changes to the rule set instructed by the update comply with at least a first set of rule-compliance-criteria and, if so, the network node is configured to modify the rule set to implement the changes of the update and, if not, the network node is configured not to implement the changes to the rule set.

Abstract: 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.
