Hi Ingemar,

Thanks for your contributions. I linked your doc to the https://l4steam.github.io/#prague-requirements-compliance web page (and will do so for others).

I didn't see any issues or objections mentioned to the current requirements as specified in the draft. Does this mean you think they are all reasonable, valid and feasible?

Interesting observation (related to the performance optimization topic 1) that for the control packets "RTCP is likely not using ECT(1)". Why is this not likely? I assume this will impact the performance? Do we need to recommend the use of ECT(1) on RTCP packets in the draft?

Thanks,
Koen.

Hi
Please find attached (hopefully) a Prague requirements survey applied to SCReAM (RFC8298 std + running code)

Subject: [tsvwg] Prague requirements survey

Hi all,

To get a better understanding on the level of consensus on the Prague requirements, we prepared an overview document listing the L4S-ID draft requirements specific to the CC (wider Prague requirements), as a questionnaire towards potential CC developers. If you are developing or have developed an L4S congestion control, you can describe the status of your ongoing development in the second last column. If you cannot share status, or plan-to/would implement an L4S CC, you can list what you would want to support (see feasible). In the last column you can put any description/limitations/remarks/explanations related to evaluations, implementations and/or plans (will implement or will not implement). Any expected or experienced issues and any objections/disagreements to the requirement can be explained and colored appropriately.

The document can be found on following link: https://raw.githubusercontent.com/L4STeam/l4steam.github.io/master/PragueReqs/Prague_requirements_Compliance_and_Objections_template.docx<https://protect2.fireeye.com/v1/url?k=d16bc960-8ef0f066-d16b89fb-86ee86bd5107-080c65bfd839440d&q=1&e=7dbb7494-67c3-4315-88a6-325f32e4e8b1&u=https%3A%2F%2Fraw.githubusercontent.com%2FL4STeam%2Fl4steam.github.io%2Fmaster%2FPragueReqs%2FPrague_requirements_Compliance_and_Objections_template.docx>

As an example I filled it for the Linux TCP-Prague implementation on following link: https://l4steam.github.io/PragueReqs/Prague_requirements_Compliance_and_Objections_Linux_TCP-Prague.docx<https://protect2.fireeye.com/v1/url?k=f839c5f7-a7a2fcf1-f839856c-86ee86bd5107-29dabadc5d0e673d&q=1&e=7dbb7494-67c3-4315-88a6-325f32e4e8b1&u=https%3A%2F%2Fl4steam.github.io%2FPragueReqs%2FPrague_requirements_Compliance_and_Objections_Linux_TCP-Prague.docx>

Please send your filled document to the list (Not sure if an attachment will work, so I assume you also need to store it somewhere and send a link to it, or send to me directly).

We hope to collect many answers, understanding the position of the different (potential) implementers and come faster to consensus.

Thanks,
Koen.
