Re: [ippm] Adoption call for Explicit Flow Measurements Techniques

[Giuseppe Fioccola <[e-mail]>]

Hi Haoyu,
The methods described in this document, if applied to encrypted protocols, need to use unencrypted header fields in order to enable the on-path measurements. That is the case of the examples for QUIC and TCP. In this regard, note that the spin bit has already been defined in the QUIC short packet header (RFC9000).

We can further clarify this point in the next version.

Regards,

Giuseppe

IPPM WG and chairs,

The proposed method is interesting and useful. I support the WG adoption.
I have a question to the authors. The draft says that the method is valuable for encrypted transport headers but later it suggested to encapsulate the bits in QUIC and TCP header. How does that work if the transport header is encrypted?

Best regards,
Haoyu

Hello IPPM,

This email starts an adoption call for draft-mdt-ippm-explicit-flow-measurements, "Explicit Flow Measurements Techniques". This document is proposed as an Informational document that describes techniques that go beyond single bit markings like the QUIC spin bit.

This adoption call will last until Friday, October 22. Please review the document, and reply to this email thread to indicate if you think IPPM should adopt this document.

Best,
Tommy
