A network device for a communications network includes a port configured to transmit data to the network at a maximum transmit data rate. The device also includes a transmit buffer configured to buffer data units that are ready for transmission to the network, and a packet buffer configured to buffer data units before the data units are ready for transmission. The packet buffer is configured to output data units at a maximum packet buffer transmission rate faster than the maximum transmit data rate. The device includes a rate controller configured to control a transmission rate of data from the packet buffer to the transmit buffer so that averaged over a period, the transmission rate from the packet buffer to the transmit buffer is at most equal to the maximum transmit data rate, while allowing the transmission rate, at one or more time intervals, to exceed the maximum transmit data rate.

A method is provided of detecting packet error during a transmission of a flit along a path from a source node through one or more intermediate nodes to a destination node. The method includes identifying a stalled node, from among the source and intermediate nodes, which prevents the transmission of the flit. The method includes generating, by a transmitter of the stalled node, a CRC for the flit and placing the CRC in an IDLE pattern of the flit. The method includes checking, by a receiver of an intermediate node subsequent to the stalled node, the CRC for the flit. The method includes sending, by a transmitter of the intermediate node, an error code to the destination node, and releasing the nodes from the intermediate node to and including the destination node, responsive to a detection, by the intermediate node, of an error in the CRC for the flit.

A system includes a cut-through bridge including a plurality of stages within a controller for communication packet transmission to transfer data and one or more control signals successively between the stages. The system also includes a control signal interceptor within the controller operable to intercept control signals between a first stage and a second stage of the cut-through bridge. The control signal interceptor is further operable to generate a forced valid control signal for each of the control signals regardless of an error condition of the control signals. The control signal interceptor outputs the forced valid control signal for each of the control signals to the second stage of the cut-through bridge. The forced valid control signal for each of the control signals is propagated through one or more successive stages of the cut-through bridge to an end stage to prevent an invalid state at the end stage.

A packet processing method and related devices are disclosed. The method includes step of slicing and encapsulating a client packet based on a preset slice length, and adding a tag value to each slice, here the tag value is used to identify characteristic information of the client packet in the slice; and then outputting encapsulated slices.

The present disclosure is directed in part to heterocycles, and their use in treating medical disorders, such as immune inflammatory disorders such as Crohn's disease, ulcerative colitis, rheumatic disorders, psoriasis, and allergies. The compounds are contemplated to modulate T-Cell responses. ##STR00001##

Techniques and solutions are provided for detecting the source of link errors in a cut-through forwarding network fabric. For example, a network link that is the source of the link errors can be automatically located by polling a network device a number of times to identify a network interface that has an increasing error rate and tracing network interface error rates back through one or more upstream network devices to locate the network link that is the source of the link errors.

The present disclosure is directed to extracting features from a NoC for machine learning construction. Example implementations include a method for generating a Network on Chip (NoC), wherein the method can extract at least one feature from a NoC specification to derive at least one of: grid features, traffic features and topological features associated with the NoC. The method can perform a process on the at least one of the grid features, the traffic features and the topological features associated with the NoC to determine at least one of an evaluation of at least one mapping strategy selected from a plurality of mapping strategies of the NoC based on a quality metric, and the selection of the at least one mapping strategy is based on the quality metric. The method can further perform generate the NoC based on the process.

In one embodiment, a method comprises identifying, by a path computation element, essential parent devices from a nonstoring destination oriented directed acyclic graph (DODAG) topology as dominating set members belonging to a dominating set; receiving, by the path computation element, an advertisement message specifying a first dominating set member having reachability to a second dominating set member, the reachability distinct from the nonstoring DODAG topology; and generating, by the path computation element based on the advertisement message, an optimized path for reaching a destination network device in the nonstoring DODAG topology via a selected sequence of dominating set members, the optimized path providing cut-through optimization across the nonstoring DODAG topology.
