rLEDBAT: receiver-driven Low Extra Delay Background Transport for TCP
draft-irtf-iccrg-rledbat-10

Received changes through RFC Editor sync (changed state to RFC, created became rfc relationship between draft-irtf-iccrg-rledbat and RFC 9840, changed IRTF state to Published RFC)

IANA has reviewed draft-irtf-iccrg-rledbat-10 and has the following comments:

We understand that this document doesn't require any registry actions.

While it's often helpful for a document's IANA Considerations section to remain in place upon publication even if there are no actions, if the authors strongly prefer to remove it, we do not object.

[Ballot comment]
Thanks for this document; IMO it's ready for publication as an IRTF stream RFC.

Some editorial comments below:

I found the mixture of TCP RFC terminology (e.g. RCV.WND) and lowercase rLEDBAT terminology (e.g. rlwnd) a _little_ hard to read at first, but I did indeed adjust to it. was any consideration given to trying to stylistically unify these (e.g. "RLWND")?

section 2: "...middleboxes are ~a~ commonplace..."

Document Type: Experimental

Document Title: rLEDBAT: receiver-driven Low Extra Delay Background Transport for TCP

Technical Summary:
This document specifies the rLEDBAT, a set of mechanisms that enable
the execution of a less-than-best-effort congestion control algorithm
for transport protocols (eg. TCP, QUIC) at the receiver end.


Research Group:
This document is a product of the Internet Congestion Control Research Group (ICCRG).

Document Quality:
The document is a technically sound and precisely describes the proposed mechanisms. The document has been used to successfully produce 3 implementations, of which 2 of them have been commercially deployed.

Research Group Summary:

The document was first submitted to the RG as an individual submission draft-bagnulo-iccrg-rledbat in July8, 2019. The submission generated some discussion in the mailing list at that time (see https://mailarchive.ietf.org/arch/msg/iccrg/Na2BK4aTlin01gIN7O2fQ9H0C04/)

The document was adopted as a Research Group working item on February 28, 2020 with the unanimous support of all those who responded to the ICCRG chair regarding adoption (https://mailarchive.ietf.org/arch/msg/iccrg/xeLrUkMT2wA0FaYY4nS2hwf6FCI/).

The document was presented in 6 IETF meetings, namely IETF105, IETF106, IETF109, IETF112, IETF115 and IETF119

Since the initial submission of the document and the current date, several implementations have been reported in the different IETF meeting presentations. The proposed experiment is ongoing since the proposed solution has been deployed in the Internet to understand its behaviour and performance.

The RGLC was announced in March 2024. the only comments received were requests to include additional details about the described mechanisms, which were incorporated to the latest version of the document issued after the RGLC.
