超越QUIC v1：最新传输层IETF标准化工作初探
Beyond QUIC v1: A First Look at Recent Transport Layer IETF Standardization Efforts
摘要：
运输层骨化。由于过去十年的大部分研究和部署工作都集中在传输控制协议（TCP）及其扩展上，互联网工程任务组（IETF）的QUIC标准化将于2021年初完成。除了解决TCP最紧迫的问题外，QUIC还确保了其未来的可扩展性，并注定要彻底改变传输协议的格局。在这项工作中，我们首先介绍了QUIC v1之外的新兴协议及其IETF标准化工作。虽然多个拟议的扩展改进了QUIC本身，但QUIC加密上的多路复用应用底层（MASQUE）以及WebTransport提出了不同的方法来解决长期存在的问题，它们的相互作用扩展了QUIC解决传输层僵化挑战的方式。
英文摘要：
The transport layer is ossified. With most of the research and deployment efforts in the past decade focussing on the Transmission Control Protocol (TCP) and its extensions, the QUIC standardization by the Internet Engineering Task Force (IETF) is to be finalized in early 2021. In addition to addressing the most urgent issues of TCP, QUIC ensures its future extendibility and is destined to drastically change the transport protocol landscape. In this work, we present a first look at emerging protocols and their IETF standardization efforts beyond QUIC v1. While multiple proposed extensions improve on QUIC itself, Multiplexed Application Substrate over QUIC Encryption (MASQUE) as well as WebTransport present different approaches to address long-standing problems, and their interplay extends on QUIC's take to address transport layer ossification challenges.
