Claim of US Patent No. 10,924,412

1. A device comprising:a processor; and
a computer-readable medium storing instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising:
receiving network traffic from a demultiplexer via a first network interface card;
placing portions of the network traffic into a plurality of hash buckets in a memory;
processing a first portion of the portions of the network traffic in at least a first number of hash buckets of the plurality of hash buckets, wherein the device is configured with a maximum number of hash buckets to process, wherein the maximum number of hash buckets to process is less than a physical processing capability of the device; and
forwarding a second portion of the portions of the network traffic in at least a second number of hash buckets of the plurality of hash buckets to a switch via a second network interface card, wherein the second portion of the portions of the network traffic comprises an overflow of the network traffic that is in excess of the maximum number of hash buckets of the device, wherein the switch distributes the second portion of the portions of the network traffic to at least one of a plurality of overflow probes, wherein the plurality of overflow probes comprises a network function virtualization infrastructure for processing the second portion of the portions of the network traffic.
