摘要： A network traffic manager receives, from an ingress port in a group of ingress ports, a cell of a packet destined for an egress port. Upon determining that a number of cells of the packet stored in a buffer queue meets a threshold value, the manager checks whether the group of ingress ports has been assigned a token for the queue. Upon determining that the group of ingress ports has been assigned the token, the manager determines that other cells of the packet are stored in the buffer, and accordingly stores the received cell in the buffer, and stores linking information for the received cell in a receive context for the packet. When all cells of the packet have been received, the manager copies linking information for the packet cells to the buffer queue or a copy generator queue, and releases the token from the group of ingress ports.

摘要： Ingress packet processors in a device receive network packets from ingress ports. A crossbar in the device receives, from the ingress packet processors, packet data of the packets and transmits information about the packet data to a plurality of traffic managers in the device. Each traffic manager computes a total amount of packet data to be written to buffers across the plurality of traffic managers, where each traffic manager manages one or more buffers that store packet data. Each traffic manager compares the total amount of packet data to one or more threshold values. Upon determining that the total amount of packet data is equal to or greater than a threshold value, each traffic manager drops a portion of the packet data, and writes a remaining portion of the packet data to the buffers managed by the traffic manager.

摘要： The technology described in this document can be embodied in an integrated circuit device comprises a first data processing unit comprising one or more input ports for receiving incoming data, one or more inter-unit data links that couple the first data processing unit to one or more other data processing units, a first ingress management module connected to the one or more inter-unit data links, the first ingress management module configured to store the incoming data, and forward the stored data to the one or more inter-unit data links as multiple data packets, and a first ingress processing module. The integrated circuit device also comprises a second data processing unit comprising one or more output ports for transmitting outgoing data, and a second ingress management module connected to the one or more inter-unit data links.

摘要： A network traffic manager receives, from an ingress port, a cell of a packet destined for an egress port. Upon determining that a number of cells of the packet stored in a buffer queue meets a threshold value, the manager checks whether the ingress port has been assigned a token corresponding to the queue. Upon determining that the ingress port has been assigned the token, the manager determines whether other cells of the packet are stored in the buffer, in response to which the manager stores the received cell in the buffer, and stores linking information for the received cell in a receive context for the packet. When all cells of the packet have been received, the manager copies linking information for the packet cells from the receive context to the buffer queue or a copy generator queue, and releases the token from the ingress port.

摘要： A resource management system for a network device is described. A resource management system includes a resource manager configured to generate a sequence of a plurality of access time slots for a plurality of candidate entities and to redistribute access to one or more of the plurality of access time slots in the sequence based on availability and eligibility. The resource management system also includes a resource monitor configured to detect usage of each of the access time slots by each of the plurality of candidate entities.
