Abstract: 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.

Abstract: A priority queue sorting system including a priority queue and a message storage. The priority queue includes multiple priority blocks that are cascaded in order from a lowest priority block to a highest priority block. Each priority block includes a register block storing an address and an identifier, compare circuitry that compares a new identifier with the stored identifier for determining relative priority, and select circuitry that determines whether to keep or shift and replace the stored address and identifier within the priority queue based on the relative priority. The message storage stores message payloads, each pointed to by a corresponding stored address of a corresponding priority block. Each priority block contains its own compare and select circuitry and determines a keep, shift, or store operation. Thus, sorting is independent of the length of the priority queue thereby achieving deterministic sorting latency that is independent of the queue length.

Abstract: Embodiments of a device and method are disclosed. In an embodiment, a method of communications involves operating an Ethernet media access control (MAC) unit according to a rate specified in an IEEE 802.3 standard and adapting to transmit data to or from the Ethernet MAC unit at an effective data communications rate on a physical media, where the effective data communications rate is different from the rate specified by the IEEE 802.3 standard.

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.

Abstract: A method of operating a plurality of communications nodes in a 10BASE-T1S Ethernet network. The plurality of communications nodes are configured to implement a physical layer collision avoidance, PLCA, process. At least two of the communications nodes are candidate beacon generators. The method comprises: for each of the at least two candidate beacon generators, determining a time delay since a last received beacon, comparing the determined time delay with a threshold value associated with the candidate beacon generator, and if the time delay exceeds the threshold value then setting that candidate beacon generator as an in-use beacon generator; and the in-use beacon generator transmitting a beacon to define the start of a PLCA cycle, thereby triggering a transmit opportunity for each of the other communication nodes.
