拥塞控制协议的研究历史表明，要找到一个最优的解决方案来应对不断发展的互联网的所有挑战是很困难的。作为一种替代范式，最近的研究建议用擦除编码技术取代拥塞控制。在本文中，我们提出了该方法的性能研究，并将其与基于TCP的解决方案进行了比较。为了更深入地研究这种新的传输模式，我们开发并实现了一种新的传输协议(基于数字喷泉的通信协议，DFCP)，其中基于数字喷泉的高效擦除编码方案起到纠正分组丢失的作用。我们给出了一些分析和模拟结果，以及我们在试验床环境中的首次性能比较。
The research history of congestion control protocols has unveiled that it is difficult to find an optimal solution, which meets all the challenges of the evolving Internet. As an alternative paradigm recent studies suggest replacing congestion control with erasure coding techniques. In this paper we present a performance study of this approach comparing it with TCP based solutions. In order to investigate the new paradigm in details and also in practice, we have developed and implemented a novel transport protocol (Digital Fountain based Communication Protocol, DFCP) where an efficient digital fountain based erasure coding scheme plays the role of correcting packet loss. We present some analytical and simulation results together with our first performance comparisons in a testbed environment.
