  • Efficient use of buffer space in a network switch
    Patent number: 10387074
    Abstract: Communication apparatus includes multiple ports configured to serve as ingress ports and egress ports for connection to a packet data network. A memory is coupled to the ports and configured to contain both respective input buffers allocated to the ingress ports and a shared buffer holding data packets for transmission in multiple queues via the egress ports. Control logic is configured to monitor an overall occupancy level of the memory, and when a data packet is received through an ingress port having an input buffer that is fully occupied while the overall occupancy level of the memory is below a specified maximum, to allocate additional space in the memory to the input buffer and to accept the received data packet into the additional space.
    Type: Grant

  • Flexible allocation of packet buffers
    Patent number: 10069701
    Abstract: Communication apparatus includes multiple ports configured to serve as ingress ports and egress ports for connection to a packet data network. A single memory array is coupled to the ports and configured to contain both a respective headroom allocation for each ingress port and a shared buffer holding data packets for transmission in multiple queues via the egress ports. Control logic is configured to adjustably allocate to each ingress port a respective volume of memory within the single memory array to serve as the respective headroom allocation, and to queue the data packets in the multiple queues in the single memory array for transmission through the egress ports.
