6. 参考文献

本节列出 HTTP Datagrams and the Capsule Protocol 使用的规范性和资料性参考文献. 规范性引用定义 HTTP/1.1、HTTP/2、HTTP/3、QUIC、QUIC DATAGRAM、Structured Fields、TCP 和 IANA 注册流程, 是 Capsule Protocol 和 HTTP Datagram 承载语义的基础. 资料性引用提供路径 MTU 发现、Extended CONNECT、HTTP 优先级和 WebSocket 等背景.

这些文献共同说明 HTTP Datagram 如何跨不同 HTTP 版本承载不可靠数据报, 以及 Capsule Protocol 如何在流式 HTTP 连接中表达控制信息. 英文标题、作者、DOI 和 URL 保持原文, 以便准确引用.
