摘要

由于标准化过程引起了极大的兴趣，QUIC可以被视为下一个通用传输协议。但是，它还没有提供真正的多路径支持，缺少multipath TCP地址的一些用例。为了填补这一空白，IETF最近采用了一项合并了几种提议设计的多路径提案。虽然它专注于其核心组件，但仍然存在一个主要的设计问题:应该使用的数据包数空间的数量。本文提供了基于NS3仿真的两种不同的多路径QUIC实现的实验结果，以了解每条路径使用一个包数空间或整个连接使用单个包数空间的影响。我们的研究结果表明，每条路径使用一个数据包数空间使多路径QUIC对接收方的启发式识别数据包和检测重复更有弹性。

The packet number space debate in multipath QUIC

With a standardization process that attracted much interest, QUIC can been seen as the next general-purpose transport protocol. Still, it does not provide true multipath support yet, missing some use cases that Multipath TCP addresses. To fill that gap, the IETF recently adopted a Multipath proposal merging several proposed designs. While it focuses on its core components, there still remains one major design issue: the amount of packet number spaces that should be used. This paper provides experimental results with two different Multipath QUIC implementations based on NS3 simulations to understand the impact of using one packet number space per path or a single packet number space for the whole connection. Our results show that using one packet number space per path makes Multipath QUIC more resilient to the receiver's heuristics to acknowledge packets and detect duplicates.

期刊介绍： Computer Communication Review (CCR) is an online publication of the ACM Special Interest Group on Data Communication (SIGCOMM) and publishes articles on topics within the SIG''s field of interest. Technical papers accepted to CCR typically report on practical advances or the practical applications of theoretical advances. CCR serves as a forum for interesting and novel ideas at an early stage in their development. The focus is on timely dissemination of new ideas that may help trigger additional investigations. While the innovation and timeliness are the major criteria for its acceptance, technical robustness and readability will also be considered in the review process. We particularly encourage papers with early evaluation or feasibility studies.
