摘要： A pre-scaled accumulated byte count of a port of a network node over a sampling period is scaled with a scaling factor to generate a scaled accumulated byte count. The pre-scaled accumulated byte count represents a total number of bytes in packets transferred by the port. The scaling factor represents a first port-specific attribute of the port and scales a port-specific maximum throughput of the port to a specific maximum port throughput of the network node. An iterative vector encoding method is applied to the scaled accumulated byte count to generate an encoded bit vector comprising bits respectively ordered bit positions. Each set bit of the encoded bit vector represents a respective weighted value of port utilization of the port. The encoded bit vector is stored, at a map location, in an operational statistics map.

摘要： Packet metadata for incoming packets are buffered in queue selection buffers associated with a port of a network node. Packet data for outgoing packets are buffered in a port selection buffer associated with the port. At a selection clock cycle, while a port scheduler of the network node selects a subset of the packet data for a subset of the outgoing packets from the port selection buffer, a queue scheduler of the port concurrently selects a subset of the packet metadata for a subset of the incoming packets from the queue selection buffers and adds new packet data for new outgoing packets to the port selection buffer of the port. The new packet data are derived based at least in part on the subset of the packet metadata for the subset of the incoming packets.
