HTTPの通信をBrotliの辞書で圧縮する『Feature: Compression dictionary transport with Shared Brotli』がある。
If the browser and server share a dictionary, using the dictionary for compression can significantly reduce the amount of data transferred. This is especially useful for incremental library updates, or when browsing multiple pages that have a lot of common parts in their files.
HTTP Dictionary Compression
— ゆき (@flano_yuki) 2023年3月26日
Bundlerとかでdictionaryを生成しとくとかやるのか。
Webサーバ(ミドルウェア)のレイヤでキャッシュに積んでく感じのイメージでいた
Q. Are the dictionaries bound to the session or connection or are they percistent?
A. They are percistent. As long as they are in a cace they can used later.
Q. Security?
A. They need to be treated like a cookie. Like a cookie and a cache.
Q. What if client gets multiple dictionaries.
A. operate apon best match. Goal is to only have one possible match. How to do that is still in the air. Server only sends one dictionary.
This seems like it is workable.

TCP ACK Rate Request (TARR) option
draft-ietf-tcpm-ack-rate-request
Intended status: Experimental
draft-ietf-tcpm-ack-rate-request-01 - TCP ACK Rate Request Option
TCP Delayed Acknowledgments (ACKs) is a widely deployed mechanism that allows reducing protocol overhead in many scenarios. However, Delayed ACKs may also contribute to suboptimal performance. When a relatively large congestion window (cwnd) can be used, less frequent ACKs may be desirable. On the other hand, in relatively small cwnd scenarios, eliciting an immediate ACK may avoid unnecessary delays that may be incurred by the Delayed ACKs mechanism. This document specifies the TCP ACK Rate Request (TARR) option. This option allows a sender to request the ACK rate to be used by a receiver, and it also allows to request immediate ACKs from a receiver.
Service Affinity Solution for TCP based Application in Anycast Situation

Service Affinity Solution for TCP based Application in Anycast Situation
draft-wang-tcpm-tcp-service-affinity-option-01
Abstract
This draft proposes a service affinity solution between client and
server based on the newly defined TCP Option. This solution can
avoid the waste of resources caused by saving a large amount of
customer status data in the network equipment, and realize the
optimized scheduling of resources based on network conditions and
computing power resources in the distributed computing power network
scenario, so as to realize the reasonable operation of cloud network
resources.
セキュリティ的に問題があるというのが会場の人からの意見。実装する人も他にいないならなし。

Aggregated Option for SYN Option Space Extension

Aggregated Option for SYN Option Space Extension
draft-nishida-tcpm-agg-syn-ext-03
Abstract
TCP option space is scarce resource as its maximum length is limited
to 40 bytes. This limitation becomes more significant in SYN
segments as all options used in a connection should be exchanged
during SYN negotiations. This document proposes a new SYN option
negotiation scheme that can aggregate multiple TCP options in SYN
segments into a single option so that more options can be negotiate
during 3-way handshake. With its simple design, the approach does
not require fundamental changes in TCP.
