  • Publication number: 20210203620
    Abstract: A first node of a packet switched network transmits at least one flow of protocol data units of a network to at least one output context of one of a plurality of second nodes of the network. The first node includes X virtual output queues (VOQs). The first node receives, from at least one of the second nodes, at least one fair rate record. Each fair rate record corresponds to a particular second node output context and describes a recommended rate of flow to the particular output context. The first node allocates up to X of the VOQs among flows corresponding to i) currently allocated VOQs, and ii) the flows corresponding to the received fair rate records. The first node operates each allocated VOQ according to the corresponding recommended rate of flow until a deallocation condition obtains for the each allocated VOQ.

  • Patent number: 10986026
    Abstract: A network device includes network ports to communicate with source devices and destination devices. The network device receives respective packets from each source device and, for each source device, respectively performs the following operations. The network device stores the respective packets in a shared memory that stores all packets from all of the source devices, and dequeues the respective packets from the shared memory to send the packets to destination devices. Responsive to the storing and the dequeuing, the network device respectively increases and decreases an input packet count for the source device. The network device determines for the source device a packet sending rate based on the input packet count and a flow control threshold common across all of the source devices in accordance with a proportional integral (PI) control equation. The network device transmits to the source device a control message including the packet sending rate.

  • Publication number: 20210112576
    Abstract: The present disclosure provides an information processing method and apparatus. A terminal device encodes uplink control information (UCI) to obtain coded bits of the UCI, and encodes data to obtain coded bits of the data. The terminal device multiplexes the coded bits of the UCI and the coded bits of the data to obtain a multiplexed bit sequence. The terminal device then transmits the multiplexed bit sequence to a network device via a physical uplink shared channel (PUSCH). A length of a transmission time interval of the UCI is less than or equal to 0.5 millisecond. In this way, data transmission latency can be reduced.
