Abstract

Selecting a receive side scaling (RSS) key is provided. It is determined whether a defined time interval expired. In response to determining that the defined time interval has expired, it is determined whether one or more keys in a set of randomly generated candidate RSS keys have a higher packet distribution score than an active RSS key. In response to determining that one or more keys in the set of randomly generated candidate RSS keys have a higher packet distribution score than the active RSS key, an RSS key having a highest packet distribution score is selected from the one or more keys in the set of randomly generated candidate RSS keys that have a higher packet distribution score than the active RSS key. The RSS key having the highest packet distribution score is used to distribute incoming network packets across a plurality of processors.

Claims8

Dependent claims

A computer-implemented method for selecting a receive side scaling (RSS) key, the computer-implemented method comprising:

determining, by a data processing system, whether a defined time interval expired;
responsive to the data processing system determining that the defined time interval has expired, determining, by the data processing system, whether one or more keys in a set of randomly generated candidate RSS keys have a higher packet distribution score than an active RSS key;
responsive to the data processing system determining that the one or more keys in the set of randomly generated candidate RSS keys have the higher packet distribution score than the active RSS key, selecting, by the data processing system, an RSS key having a highest packet distribution score from the one or more keys in the set of randomly generated candidate RSS keys that have the higher packet distribution score than the active RSS key;
and
using, by the data processing system, the RSS key having the highest packet distribution score to distribute incoming network packets across a plurality of processors corresponding to the data processing system.
