译自：Choosing the Right Transport Protocol: TCP vs. UDP vs. QUIC 作者：Ron Northcutt一个决策框架，它分解了各种协议的优缺点和理想用例，以帮助用户为其系统选择合适的协议。我们常常认为协议选择纯粹是一个技术决策，但它对用户体验和应用程序的消费方式至关重要。这是一个高影响力的业务决策，因此技术团队...
队头阻塞顽疾:即便HTTP/2多路复用,TCP层仍存在传输级阻塞 移动网络适配差:WiFi/4G切换导致连接重置(实测淘宝APP切换网络时HTTP/2失败率17%) 加密与协议分层:TLS over TCP导致协议栈处理复杂度飙升 深度思考:TCP的可靠传输机制是否已成为新时代的枷锁?当QUIC将拥塞控制算法从内核态移至用户态,我们是否正在见证传输层...

TCPQUICLTESimulationNS-3In the vast majority of mobile applications, the Transmission Control Protocol (TCP) is still leveraged at the transport layer of the Internet's protocol stack. But, in many cases, the performance of TCP over mobile networks has been proven sub-optimal in practice, thus...
TCP has been the workhorse of the web for a long time, and a lot of effort has gone into optimizing its implementations over the years to make it more computationally efficient. QUIC however, is still a nascent protocol; it has yet to be widely deployed and tuned for computational efficienc...
0-RTT 是 TLS 1.3 中的一项性能优化功能,依赖于预共享密钥(PSK),允许客户端在会话恢复时立即发送数据,而无需等待服务器响应。根据RFC 8446 - The Transport Layer Security (TLS) Protocol Version 1.3,0-RTT 数据在加密后发送,但存在重放攻击风险,因此服务器需确保数据是幂等的(如 GET 请求)。
MQTT over QUIC: As of now, MQTT over QUIC is not as widely supported or adopted, as QUIC is still an emerging protocol. Learn more in our detailed guide to QUIC vs TCP (coming soon) MQTT Over QUIC Use Cases in IoV MQTT over QUIC can be beneficial in the Internet of Vehicles (IoV)...
QUIC(RFC9000) 是下一代互联网协议 HTTP/3 的底层传输协议,与 TCP/TLS 协议相比,它在减少连接开销与消息延迟的同时,为现代移动互联网提供了有效灵活的传输层。 EMQX 5.0 是首个将 QUIC 引入 MQTT 的开创性产品。在长期的客户服务和技术探索中,我们注意到 QUIC 的特性能够和一些物联网场景完美契合,于是尝试将...
TCP(Transmission Control Protocol)传输控制协议于1981在RFC 793中定义,主要特性是数据传输可靠性。 基于UDP与TCP的特性,如果要实现可靠数据传输,TCP是较为简单的选型,但是在网络传输通道质量较差的情况下,如丢包、延迟率较高、带宽受限等,会产生建立连接的握手延迟大、队头阻塞、网络拥塞等问题。
QUIC vs TCP/TLS Easier to use: MQTT over QUIC SDK Future EMQX QUIC Epilogue In the latest version 5.0, EMQX made a breakthrough by relaying MQTT message over QUIC protocol. QUIC (RFC 9000) is the underlying transport protocol of the next-generation Internet protocol HTTP/3, which provides ...
