Dear All, I have added a new section about measurements and results to demonstrate what difference the usage of multiple IP addresses can make: https://datatracker.ietf.org/doc/html/draft-lencse-bmwg-multiple-ip-addresses#name-experiments-and-results Your comments are welcome! Best regards, Gábor -------- Továbbított üzenet -------- Tárgy: New Version Notification for draft-lencse-bmwg-multiple-ip-addresses-01.txt Dátum: Mon, 04 Mar 2024 12:30:15 -0800 Feladó: internet-drafts@ietf.org Címzett: Gábor Lencse <lencse@sze.hu>, Gabor Lencse <lencse@sze.hu>, Keiichi Shima <shima@wide.ad.jp> A new version of Internet-Draft draft-lencse-bmwg-multiple-ip-addresses-01.txt has been successfully submitted by Gábor Lencse and posted to the IETF repository. Name: draft-lencse-bmwg-multiple-ip-addresses Revision: 01 Title: Recommendations for using Multiple IP Addresses in Benchmarking Tests Date: 2024-03-04 Group: Individual Submission Pages: 9 URL: https://www.ietf.org/archive/id/draft-lencse-bmwg-multiple-ip-addresses-01.txt Status: https://datatracker.ietf.org/doc/draft-lencse-bmwg-multiple-ip-addresses/ HTMLized: https://datatracker.ietf.org/doc/html/draft-lencse-bmwg-multiple-ip-addresses Diff: https://author-tools.ietf.org/iddiff?url2=draft-lencse-bmwg-multiple-ip-addresses-01 Abstract: RFC 2544 has defined a benchmarking methodology for network interconnect devices. Its test frame format contained fixed IP addresses and fixed port numbers. RFC 4814 introduced pseudorandom port numbers, but it kept the usage of a single source and destination IP address pair when a single destination network is used. This limitation may cause an issue when the device under test uses Receive-Side Scaling (RSS) mechanism in the packet processing flow. RSS has two types of implementations: the first one only includes the IP addresses, whereas the second one also includes the port numbers into the tuple used for hashing. Benchmarking tests that use a single IP address pair and RFC 4814 pseudorandom port numbers are biased against the first type of RSS implementation, because in this case, the traffic is not distributed among the processing elements. This document recommends the usage of pseudorandom IP addresses in a similar manner as RFC 4814 did it with the port numbers. If accepted, this document updates all affected RFCs, including RFC 2544, RFC 4814, RFC 5180, RFC 8219. The IETF Secretariat
