A method for processing network packets in a network device is described. A network packet is stored in a transient buffer as the network packet is being received at an ingress port of the network device. After at least a first portion of the network packet has been received and before the entire network packet has been received: the first portion is processed to identify an egress port of the network device from which the network packet is to be transmitted; a congestion state of the egress port is determined; and the network packet is selectively transferred from the transient buffer to the identified egress port for transmission from the network device or a different action is performed on the network packet, based on the congestion state.

A method and a data bus subscriber are described for processing process data in a local bus, in particular a ring bus, the method including receiving a first symbol during a first number of working cycles, with the first symbol comprising first process data; loading at least one first instruction from an instruction list during the first number of working cycles, receiving a second symbol during a second number of working cycles, with the second symbol comprising second process data, processing the first process data contained in the first symbol with the at least one loaded first instruction during the second number of working cycles, and loading at least one second instruction for processing the second process data of the second symbol during the second number of working cycles.

A data bus subscriber and a method for processing data, wherein the data bus subscriber can be connected to a local bus, particularly a ring bus, and the data bus subscriber has an input interface, which can be connected to the local bus, for receiving first local bus data, an output interface, which can be connected to the local bus, for transmitting second local bus data, a processing component for synchronous processing of the first local bus data and/or data stored in a memory and for output of at least one control signal, a logic unit, which is adapted in order to modify a quantity of received first local bus data based on the control signal in order to generate the second local bus data to be transmitted, wherein the logic unit is further adapted for synchronous, delayed transmitting of the second local bus data via the output interface.

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.

In the subject system for a network switch may determine to transition the output port of the network switch between a store-and-forward (SAF) state and a cut-through (CT) state based on at least one factor. The network switch may determine, based on a condition of the output port, whether to transition the output port to a transition-cut-through (TCT) state or directly to a CT state when transitioning the output port to the CT state. When the output port is transitioned to the TCT state, the network switch may determine, based on the condition of the output port, whether to transition the output port to the CT state or to transition the output port back to the SAF state.

The present invention relates to a method for removing data frame redundancy in a network environment and a device for carrying out the method, which can comprise: a data frame reception step of receiving a first data frame from an adjacent node; and a redundant frame determination step of determining whether a reception completion indicator of a second data frame having the same identification information as the first data frame exists, on the basis of a preset redundancy check table, and processing the first data frame according to the determination result. Disclosed is the data frame redundancy removal method, which deletes the first data frame when the reception completion indicator of the second data frame having the same identification information as the first data frame exists in the redundancy check table.

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.

In one embodiment, an apparatus includes a switch core that has a multi-stage switch fabric. A first set of peripheral processing devices coupled to the multi-stage switch fabric by a set of connections that have a protocol. Each peripheral processing device from the first set of peripheral processing devices is a storage node that has virtualized resources. The virtualized resources of the first set of peripheral processing devices collectively define a virtual storage resource interconnected by the switch core. A second set of peripheral processing devices coupled to the multi-stage switch fabric by a set of connections that have the protocol. Each peripheral processing device from the first set of peripheral processing devices is a compute node that has virtualized resources. The virtualized resources of the second set of peripheral processing devices collectively define a virtual compute resource interconnected by the switch core.

This disclosure describes enhancements to Ethernet for use in higher performance applications like Storage, HPC, and Ethernet based fabric interconnects. This disclosure provides various mechanisms for lossless fabric enhancements with error-detection and retransmissions to improve link reliability, frame pre-emption to allow higher priority traffic over lower priority traffic, virtual channel support for deadlock avoidance by enhancing Class of service functionality defined in IEEE 802.1Q, a new header format for efficient forwarding/routing in the fabric interconnect and header CRC for reliable cut-through forwarding in the fabric interconnect. The enhancements described herein, when added to standard and/or proprietary Ethernet protocols, broadens the applicability of Ethernet to newer usage models and fabric interconnects that are currently served by alternate fabric technologies like Infiniband, Fibre Channel and/or other proprietary technologies, etc.
