Abstract: In one embodiment, a computer apparatus includes a first NIC including at least one network interface port to transfer data with a first packet-data network (PDN) including a master clock to provide a clock synchronization signal S1, a first physical hardware clock (PHC) to maintain a time value T1 responsively to S1, and a first clock controller to generate a clock synchronization signal S2 responsively to S1, S2 having a frequency set responsively to S1, and send S2 over a connection to a second NIC including at least one network interface port to transfer data with a second PDN, a second PHC, and a second clock controller to receive S2, update the second PHC with a time value T2 responsively to S2, send another clock synchronization signal to network nodes in the second PDN responsively to T2, the second NIC acting as a master clock in the second PDN.

Abstract: One embodiment includes a network device, including hardware parsers to receive data of a header section of a packet, the header section including respective headers, parser configuration registers to store a default parsing configuration data set, wherein at least one of the hardware parsers is configured to parse at least one of the headers responsively to the default parsing configuration data set, yielding first parsed data, a packet processing engine to select a selected parsing configuration data set from a selection of parsing configuration data sets responsively to the first parsed data, cause loading of the selected parsing configuration data set into the parser configuration registers, and wherein ones of the hardware parsers are configured to parse respective ones of the headers responsively to the selected parsing configuration data set, yielding second parsed data, and process the packet responsively to the second parsed data.
