9. 参考文献 (References)
本节列出本文档引用的规范性和信息性参考文献. 为保持引用可核验性, 文献条目的作者姓名, 英文题名, 出版物名称, RFC 编号, DOI, URL 和日期等元数据按原文保留. 中文说明用于标明这些条目是协议规范, 标准文档, 实现资料或背景资料, 读者可据此追溯原始来源.
RFC 9002 的引用集中在 QUIC 传输、QUIC TLS、ECN、UDP 使用指南以及 TCP 拥塞控制研究. 规范性引用定义 QUIC loss detection 和 congestion control 必须依赖的传输语义; 资料性引用则提供 TCP 领域中已有的快速恢复、RTO 估算、SACK、CUBIC、RACK-TLP 和 ECN 回退经验. 这些背景有助于理解 QUIC 为什么采用自己的包号空间、ACK 处理和丢包检测机制.
9.1. 规范性参考文献 (Normative References)
规范性文献用于确定 QUIC 如何在 UDP 上安全运行, 如何解释 ECN 信号, 以及规范性关键词如何约束实现行为.

9.2. 资料性参考文献 (Informative References)
资料性文献用于解释拥塞控制和丢包恢复算法的历史来源. 它们不直接替代 RFC 9002 的算法, 但能帮助实现者理解为何需要慢启动、拥塞避免、恢复期、RTO/PTO 估算和 ACK 相关启发式.
实现者阅读这些资料性文献时, 应注意 QUIC 与 TCP 的差异: QUIC 在用户空间实现, 使用独立包号空间, ACK 语义和加密握手状态也不同于传统 TCP. 因此, TCP 文献提供的是算法设计经验, 不是可以逐字复制的规范要求.
从调试角度看, 这些引用还可用于定位实现问题: 如果 PTO 计算异常, 应回看重传计时器和 QUIC 传输规范; 如果拥塞窗口增长或下降异常, 应对照 TCP 拥塞控制、CUBIC、PRR 和 ECN 相关文献理解设计取舍.
