Receive Side Scaling Configuration

The Receive Side Scaling (RSS) hashing algorithm relies on a combination of different attributes to calculate the hash value. These attributes include the source and destination IP addresses, protocol type, and port numbers associated with each incoming packet. By considering these factors, the algorithm distributes the network traffic evenly across multiple receive queues, facilitating efficient load balancing and maximizing the performance of the system. To ensure the accuracy of the RSS hash calculation and gain a deeper understanding of the process, the following command can be used:.

This command enables verbose mode in DPDK, providing more detailed output to observe the calculated hash values for each packet and understand how DPDK determines the appropriate receive queue for packet distribution.
