System and method for processing networking packets using a reorder queue

A system comprising:

• a filter;
• and
• an offload engine comprising a scheduler, a plurality of processing cores, a unified flow creator, and a reorder queue;
• the filter configured to:
• receive a packet;
• determine that the packet is a first packet in a first flow;
• based at least on determining that the packet is the first packet in the first flow:
• send a copy of the packet to the packet scheduler for scheduling a processing of the packet on one of the plurality of processing cores;
• and
• send the packet to the reorder queue;
• receive another packet;
• determining that the other packet is not the first packet in the first flow;
• based at least on determining that the other packet is not the first packet in the first flow, sending the other packet to the reorder queue without sending a copy of the other packet to the packet scheduler;
• receiving, from the unified flow creator, an indication that the copy of the packet has been processed by the unified flow creator, the indication comprising a unified flow created by the unified flow creator, the unified flow comprising information on how to process each packet in the first flow based on the processing of the packet;
• receiving the packet and the other packet for the first flow in a first in first out order from the reorder queue, the packet being released from the reorder queue based at least on the indication that the copy of the packet has been processed by the unified flow creator;
• and
• processing the packet and the other packet based on the unified flow and an order in which they are received from the reorder queue.

A computer-storage medium comprising computer-executable instructions that, when executed by a processor, cause the processor to perform the following operations:

• receiving a packet;
• determining that the packet is a first packet in a first flow;
• based at least on determining that the packet is the first packet in the first flow, sending the packet to a reorder queue and sending a copy of the packet to a packet scheduler;
• receiving another packet;
• determining that the other packet is not the first packet in the first flow;
• based at least on determining that the other packet is not the first packet in the first flow, sending the other packet to the reorder queue without sending a copy of the other packet the reorder queue;
• receiving an indication that the copy of the packet has been processed by a unified flow creator, the indication comprising a unified flow generated by the unified flow creator that includes information on how to process each packet in the first flow based on the processing of the copy of the packet;
• receiving the packet and the other packet for the first flow in a first in first out order from the reorder queue, the packet being released from the reorder queue based at least on the indication that the copy of the packet has been processed by the unified flow creator;
• and
• processing the first packet and the other packet in the first flow based on the unified flow and an order in which they are received from the reorder queue.
