LOAD BALANCING AMONG OUTPUT PORTS

Abstract:

Examples described herein relate to a network interface device that includes packet processing circuitry to detect usage of an egress port and report the usage of the egress port to a network interface device driver to cause reallocation of hash-based packet buckets to at least one egress port to provide an allocation of hash-based packet buckets to multiple active egress ports of the network interface device with retention of bucket-to-egress port mappings except for re-allocations of one or more buckets to one or more active egress ports. In some examples, usage of the egress port is based on a count of hash buckets assigned to packets to be transmitted from the egress port or a number of bytes of packets enqueued to be transmitted from the egress port.
