Abstract: The subject technology relates to the management of a shared buffer memory in a network switch. Systems, methods, and machine readable media are provided for receiving a data packet at a first network queue from among a plurality of network queues, determining if a fill level of a queue in a shared buffer of the network switch exceeds a dynamic queue threshold, and in an event that the fill level of the shared buffer exceeds the dynamic queue threshold, determining if a fill level of the first network queue is less than a static queue minimum threshold.

Abstract: A network device receives a packet at a port from among a number of ports. A queue threshold is randomly adjusted for a queue having an output buffer to which the packet is stored. When a fullness of the queue exceeds the adjusted queue threshold, at a time when the packet is to be enqueued into the queue, an action is performed. The action includes either dropping the received packet, or flow-controlling the port at which the packet is received.

Abstract: A network switch includes a buffer to store network packets linked to queues to feed the packets to output ports of the switch associated with the queues. The buffer is shared dynamically among multiple traffic pools. The network switch determines per-pool dynamic thresholds each based on an amount of unused buffer space, and per-queue dynamic thresholds based on amounts of unused buffer space available in the pools with which the queues are associated. The network switch receives packets, and for each received packet, the network switch admits the packet to the pool with which the packet is associated and the queue for which the packet is destined if (i) occupancy of the associated pool is less than the corresponding per-pool dynamic threshold, and (ii) occupancy of the queue for which the packet is destined is less than the corresponding per-queue dynamic threshold, and otherwise drops the packet.

Abstract: A network switch includes a buffer to store network packets and packet descriptors (PDs) used to link the packets into queues for output ports. The buffer and PDs are shared among the multiple traffic pools. The switch receives a multicast packet for queues in a given pool. The switch determines if there is unused buffer space available for packets in the given pool based on a pool dynamic threshold, if there is unused buffer space available for packets in each queue based on a queue dynamic threshold for the queue, if there are unused PDs available to the given pool based on a pool dynamic threshold for PDs, and if there are unused PDs available for each queue based on a queue dynamic threshold for PDs for the queue. The network switch admits the packet only into the queues for which all of the determining operations pass.
