Cloudflare AKE 引入后对多源 TLS 配置兼容性与延迟透明度的挑战

更新于 2026/9/21 13:20:01

问题概述

Cloudflare 通过 AKE 将 HelloRetryRequests 从 52% 降至 3.7%,但用户指出该优化未公开实际查找延迟、在多源站点间保持密钥交换偏好的准确性以及对 Cloudflare 控制的协议栈独占性的担忧,这些问题可能阻碍更广泛采用并引发对替代方案的需求。

They are saving on the *possible roundtrip latency, however they are not sharing the absolute lookup latency which now gets added to every connection
原话
Ever since http2 and especially http3 (my god did that take years to reach the mainstream), I've been sad to see intermediaries like Cloudflare gobbling up all the newest protocols and ciphersuites and etc while open source lags behind.
原话
I'm curious how Cloudflare keeps the learned key exchange preference accurate when a hostname is backed by multiple origins with different TLS configurations?
