Method of Handling Network Traffic Through Optimization of Receive Side Scaling4

摘要

An information handling system includes a plurality of processors that each includes a cache memory, and a receive side scaling (RSS) indirection table with a plurality of pointers that each points to one of the processors. A network data packet received by the information handling system determines a pointer to a first processor. In response to determining the pointer, information associated with the network data packet is transferred to the cache memory of the first processor. The information handling system also includes a process scheduler that moves a process associated with the network data packet from a second processor to the first processor, and an RSS module that directs the process scheduler to move the process and associates the first pointer with the processor in response to directing the process scheduler.

1. An network interface device comprising:
a receive side scaling (RSS) module operable to:
provide a first pointer of a plurality of pointers to point to a first processor of a plurality of processors, wherein each pointer identifies a respective processor; andprovide a first interrupt of a plurality of interrupts to be associated with the first processor, wherein each interrupt is associated with a respective processor; wherein the network interface device is operable to:
receive a first data packet;select the first pointer in response to receiving the first network data packet;transfer the first data packet to the first processor in response to selecting the first pointer; andprovide the first interrupt to the first processor in response to transferring the first data packet.
