Real-Time Adaptive Receive Side Scaling Key Selection
First Claim
1. 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 one or more keys in the set of randomly generated candidate RSS keys have a 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 a 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.

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.
