Dear BMWG Chairs and Members,

I have just submitted our new I-D "Recommendations for using Multiple IP 
Addresses in Benchmarking Tests".

It is quite short and focuses on a single problem described in its 
abstract (please see below).

Could you please read and comment it?

I would like to shortly present it at IETF 118 in Prague, in which I 
plan to take part in person -- first time in my life. :-)

Best regards,

Gábor

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.
