Cloudflare AKE 引入后对多源 TLS 配置兼容性与延迟透明度的挑战
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。
痛点标签
- 多源站点不同 TLS 配置下难以保持准确的密钥交换偏好
- 缺乏对额外查找延迟的可视化,导致实际延迟不确定
- 对 Cloudflare 垄断最新协议与密码套件的依赖使得独立服务器难以获取同等最新特性
待验证问题
- 多源站点的 TLS 配置差异是否导致实际延迟增加?
- 用户是否关注 Cloudflare 对最新协议的独占控制及其对开放生态的影响?
- 是否需要一种开放的、能够在多源环境下统一管理密钥交换偏好的标准?
证据
原话
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?
