论文摘要
互联网拥塞控制机制越来越困难获得他们需要的反馈。缺乏反馈可能会产生严重的绩效影响,并且必然会变得更糟。从长远来看,只有通过从根本上改变互联网上的拥堵控制方式,才可以解决问题。我们通过查看过去三十年来互联网基础架构的演变,并检查互联网流量的最常见行为来证实这一主张。考虑到旨在解决拥堵控制机制的目标,并考虑到互联网生态系统中的上下文发展,我们得出了有关未来的拥塞控制设计方向的结论和建议。特别是,我们认为拥塞控制机制应摆脱严格的“端到端”依从性。这种变化将受益于避免“一种适合所有情况”的方法,并朝着更具选择性的机制迈进,从而导致互联网表现更好。我们还将讨论这种未来的愿景与当今使用绩效增强代理(PEPS)的不同之处。
It is increasingly difficult for Internet congestion control mechanisms to obtain the feedback that they need. This lack of feedback can have severe performance implications, and it is bound to become worse. In the long run, the problem may only be fixable by fundamentally changing the way congestion control is done in the Internet. We substantiate this claim by looking at the evolution of the Internet's infrastructure over the past thirty years, and by examining the most common behavior of Internet traffic. Considering the goals that congestion control mechanisms are intended to address, and taking into account contextual developments in the Internet ecosystem, we arrive at conclusions and recommendations about possible future congestion control design directions. In particular, we argue that congestion control mechanisms should move away from their strict "end-to-end" adherence. This change would benefit from avoiding a "one size fits all circumstances" approach, and moving towards a more selective set of mechanisms that will result in a better performing Internet. We will also discuss how this future vision differs from today's use of Performance Enhancing Proxies (PEPs).
