Abstract: A networking system includes a pluggable security device comprising at least one port interface that is insertable into at least one physical port, memory that stores a security key used to provide security over a network link, and processing circuitry coupled with the at least one port interface and with the memory. The processing circuitry utilizes the security key to verify security of a point-to-point connection established over the network link and after verifying the security of the point-to-point connection, provides a data integrity check function for data packets received at the at least one port interface.

Abstract: A method for communication, includes routing unicast data packets among nodes in a network using respective Layer-3 addresses that are uniquely assigned to each of the nodes. Respective Layer-2 unicast addresses are assigned to the nodes in accordance with an algorithmic mapping of the respective Layer-3 addresses. The unicast data packets are forwarded within subnets of the network using the assigned Layer-2 addresses.

Abstract: A method for communication includes, in a sender node that sends packets to a receiver node over a physical link, making a decision, for a packet that is associated with a respective virtual link selected from among multiple virtual links, whether the receiver node is to buffer the packet in a dedicated buffer assigned to the respective virtual link or in a shared buffer that is shared among the multiple virtual links. The packet is sent, and the decision is signaled, from the sender node to the receiver node.

Abstract: A method includes receiving in a network element a packet, which includes a delay field that indicates an overall time delay accumulated by the packet until arriving at the network element. Upon receiving the packet, an interim value is substituted in the delay field. The interim value is indicative of a difference between the overall time delay and an arrival time of the packet at the network element. Before sending the packet from the network element, the overall time delay is updated in the delay field based on the interim value and on a departure time at which the packet is to exit the network element. The packet, including the updated overall time delay, is transmitted from the network element.

Abstract: An apparatus includes an input interface to receive incoming packets from a first network device and an output interface to send outgoing packets to a second network device. Media access control security (MACsec) circuitry is coupled between the input interface and the output interface. Bypass flow-control (FC) circuitry is coupled between the input interface and the MACsec circuitry. The bypass FC circuitry is to detect an FC packet in the incoming packets and pass the FC packet passively to the output interface to enable end-to-end flow control directly between the first network device and the second network device.

Abstract: A relay device is provided that may identify a quantity of empty data byte locations in a data buffer of the relay device. The relay device may receive an indicator associated with transmitting data packets. The relay device may pause or enable a lossless flow of data between the relay device, a host device, and a peer device based on the quantity of empty data byte locations, the indicator, or both. The relay device may include a first data interface coupled with a peer device, a second data interface coupled with a host device, a data buffer configured to store data packets received from the host device, and a state machine that enables a lossless transmission of data between the host device and peer device. The state machine may transmit a pause frame to the host device based on a data buffer utilization reaching a data storage capacity.

Abstract: A System-On-Chip (SoC) includes a set of registers, a processor, and Out-Of-Order Write (OOOW) circuitry. The processor is to execute instructions including write instructions. After issuing a first write instruction to any of the registers in the set, the processor is to await an acknowledgement for the first write instruction before issuing a second write instruction to any of the registers in the set. The OOOW circuitry is to identify the write instructions issued by the processor to the registers in the set, to perform the identified write instructions in the registers irrespective of acknowledgements from the registers, and to send to the processor imitated acknowledgements for the identified write instructions.
