Abstract: A network element includes at least one communication port and a processor. The communication port is configured to communicate with a peer communication port of a peer network element. The processor is configured to support a full-boot mode and a fast-boot mode, to establish, by negotiation with the peer network element, whether the fast-boot mode is supported both for the communication port and for the peer communication port, and, in response to finding that the fast-boot mode is supported both for the communication port and for the peer communication port, to coordinate with the peer network element a boot of the communication port and of the peer communication port, both using the fast-boot mode.

Abstract: A method including determining, for a given hardware link, whether a signal error rate for signals sent over the given hardware link is beyond a given threshold, when the signal error rate is beyond the given threshold, generating an error indication for the given hardware link, the error indication including a prediction that a hardware component associated with the given hardware link is likely to fail. Related apparatus and methods are also provided.

Abstract: A method including providing a network switch, including switching circuitry, packet drop decision circuitry, packet duplication circuitry, and packet exporting circuitry, and performing the following in the network switch: switching packets in the switching circuitry, identifying a packet that is to be dropped in the packet drop decision circuitry, duplicating the packet that is to be dropped in the packet duplication circuitry, producing a first packet and a second packet, exporting the first packet to a tail-drop packet buffer in the packet exporting circuitry, and exporting the second packet to a cyclic packet buffer in the packet exporting circuitry. Related apparatus and methods are also provided. The abstract is not intended to be limiting.

Abstract: In one embodiment, a software and hardware development method include providing a software-hardware interface to provide a data interface between hardware of an application specific integrated circuit (ASIC) and software running on a processor, providing control of a given part of the software-hardware interface to a software feature thereby yielding a more stable software-hardware interface, receiving a request to change the controlled given part of the software-hardware interface, and providing a message responsively to the request to change the controlled given part of the software-hardware interface.
