摘要： Systems, methods, and other embodiments associated with wake-on-frame mechanisms are described. According to one embodiment, an apparatus includes a packet source configured to send packets to a frame processing device and a wake-on-frame mechanism that is selectable by the frame processing device between an enabled state and a disabled state. If the wake-on-frame mechanism is in the enabled state, a packet source that has a frame to send to the frame processing device sends a wake signal to the frame processing device prior to sending the packet. The packet source sends the packet to the frame processing device after receiving a ready signal from the frame processing device.

摘要： A network switching device comprises first and second ports. A queue communicates with the second port, stores frames for later output by the second port, and generates a congestion signal when filled above a threshold. A control module selectively sends an outgoing flow control message to the first port when the congestion signal is present, and selectively instructs the second port to assert flow control when a flow control message is received from the first port if the received flow control message designates the second port as a target.

摘要： A packet is received via a port of the network device, and a database lookup is performed using header information of the packet. A priority associated with the packet is determined, and it is determined whether the priority is associated with a particular communication protocol that provides guaranteed delivery, defined latency, and/or defined throughput. When it is determined that the priority is associated with the particular communication protocol, i) it is determined, based on the database lookup, whether a destination address (DA) of the packet is associated with the particular communication protocol, and ii) when it is determined that the DA of the packet is associated with the particular communication protocol, the packet is prevented from egressing from ports of the network device that are operating according to the particular communication protocol with a frame priority indicator corresponding to a value reserved for the particular communication protocol.

摘要： An apparatus including a port to transmit first frames and receive second frames over a communication channel, the port including a collision detect circuit and a duplex mismatch circuit. The collision detect circuit detects collisions on the communication channel between the first frames and the second frames. The duplex mismatch circuit declares a duplex mismatch when the communication channel was established without attempting auto-negotiation, the port is in a half-duplex mode, and the collision detect circuit detects a very late collision involving one of the first frames. The very late collision occurs after a predetermined amount of data has been transmitted in the one of the first frames. The duplex mismatch indicates that a full-duplex mode is used with respect to the second frames.

摘要： A multiport memory architecture, systems including the same and methods for using the same. The architecture generally includes (a) a memory array; (b) a plurality of ports configured to receive and/or transmit data; and (c) a plurality of port buffers, each of which is configured to transmit the data to and/or receive the data from one or more of the ports, and all of which are configured to (i) transmit the data to the memory array on a first common bus and (ii) receive the data from the memory array on a second common bus. The systems generally include those that embody one or more of the inventive concepts disclosed herein. The methods generally relate to writing blocks of data to, reading blocks of data from, and/or transferring blocks of data across a memory. The present invention advantageously reduces latency in data communications, particularly in network switches, by tightly coupling port buffers to the main memory and advantageously using point-to-point communications over long segments of the memory read and write paths, thereby reducing routing congestion and enabling the elimination of a FIFO. The invention advantageously shrinks chip size and provides increased data transmission rates and throughput, and in preferred embodiments, reduced resistance and/or capacitance in the memory read and write busses.
