Abstract: A network adapter includes a network interface, a host interface and processing circuitry. The network interface is configured to connect to a communication network. The host interface is configured to communicate with a host processor running multiple application programs. The processing circuitry includes one or more bandwidth-control policers, and is configured to receive from the communication network a packet destined to a given application program among the application programs running on the host processor, to associate a bandwidth-control policer with the packet, selected from among the bandwidth-control policers, and to apply the selected bandwidth-control policer to the packet to produce a policer result.

Abstract: Optical splitting adaptors and associated methods of manufacturing are provided. An example optical splitting adaptor includes a first connector housing that interfaces with a first optical transceiver having a first data rate, and the first connector housing accommodates a first type multi-fiber ferrule of a first number of fibers. The example optical splitting adaptor also includes a second connector housing that defines dual receptacles for interfacing with a second optical transceiver and a third optical transceiver, and the dual receptacles receive respective multi-fiber ferrules. The example optical splitting adaptor further includes a plurality of fibers operably connecting the first connector housing and the second connector housing such that, in operation, the plurality of fibers perform optical splitting between the first type multi-fiber ferrule of the first connector housing and the multi-fiber ferrules received by the dual receptacles of the second connector housing.

Abstract: A network node includes a port and circuitry. The port is configured for communicating over a packet network. The circuitry is configured to receive, via the port, a sequence of packets from a peer network node, the sequence of packets including (i) a time-protocol packet and (ii) a transmit-side (TX) time-stamp indicative of a time at which the time-protocol packet was transmitted from the peer network node, to assess a receive-side (RX) traffic pattern over one or more of the received packets in the sequence that precede reception of the time-protocol packet, and to calculate an accuracy measure for the TX time-stamp, based on the assessed RX traffic pattern.

Abstract: An example method for dynamic packet routing using prioritized groups includes: receiving, by a processing device, routing information specifying a plurality of paths to a network destination, wherein each path is associated with a respective cost metric value; associating a first subset of the plurality of paths with a first priority routing group for the network destination, wherein each path of the first subset satisfies a first cost criterion based on a cost metric value of the path; associating a second subset of the plurality of paths with a second priority routing group for the network destination, wherein each path of the second subset satisfies a second cost criterion; and storing, in a forwarding information data structure, a first definition of the first priority routing group and a second definition of a second priority routing group.

Abstract: A network element includes one or more ports and a packet processor. The one or more ports are to transmit and receive packets over a network. The packet processor is to apply a plurality of rules to the packets, each rule specifying (i) expected values for each header field of a group of header fields of the packets, including, for a given header field in the group, at least a set of multiple expected values, (ii) a group ID associated with the set, and (iii) an action to be applied to the packets whose header fields match the expected values.

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.
