Hybrid network processing load distribution in computing systems
First Claim
1. A method for network traffic management in a computing device having a network interface controller operatively coupled to a main processor with multiple cores, the method comprising:
- receiving, at the network interface controller, a packet having a header and a payload;
assigning, at the network interface controller, the received packet to a virtual port of the network interface controller based on a destination medium access control (“
MAC”
) address contained in the header of the packet;
upon assigning the packet to the virtual port, further assigning, at the network interface controller, the packet to one of the queues in the virtual port based on one or more of a source IP address, a destination IP address, a source port, or a destination port included in the header of the packet;
upon assigning the packet to one of the queues in the virtual port, indicating to the main processor that the assigned queue of the virtual port contains the packet to be processed; and
cooperating with a core assigned by the main processor to execute network processing operations related to the packet to forward the packet in the queue to a destination identified by the MAC address, the source IP address, the destination IP address, the source port, and the destination port included in the header of the packet.

Abstract
Embodiments of hybrid network processing load distribution in a computing device are disclosed therein. In one embodiment, a method includes receiving, at a main processor, an indication from the network interface controller to perform network processing operations for first and second packets in a queue of a virtual port of the network interface controller, and in response to receiving the request, assigning first and second cores for performing the network processing operations for the first and second packets, respectively. The method also includes performing the network processing operations at the first and second cores to effect processing and transmission of the first and second packets to first and second applications, respectively, both the first and second applications executing in a virtual machine hosted on the computing device.
