随着越来越多的互联网应用的部署，对多宿主网络站点的需求不断增加。这导致需要同时利用所有可用的访问路径来提高应用数据吞吐量。这通常被称为并发多路径传输（CMT）;已经提出了几种传输层协议的方法。与资源池（RP）相结合，CMT也可以与非CMT并发流公平共存。目前的方法集中在对称路径（即类似的带宽，延迟和错误率）。然而，非对称路径更有可能--特别是对于现实的Internet设置--因此在此类路径上有效使用CMT至关重要。在本文中，我们首先显示的挑战，以及RP感知CMT数据传输的非对称路径。在此之后，我们介绍了在这样的路径上的有效传输机制。最后，我们通过模拟分析我们的方法的性能。
With the deployment of more and more resilience-critical Internet applications, there is a rising demand for multi-homed network sites. This leads to the desire for simultaneously utilising all available access paths to improve application data throughput. This is commonly known as Concurrent Multipath Transfer (CMT); approaches for several Transport Layer protocols have been proposed. Combined with Resource Pooling~(RP), CMT can also fairly coexist with concurrent non-CMT flows. Current approaches focus on symmetric paths (i.e. similar bandwidth, delay and error rate). However, asymmetric paths are much more likely -- particularly for realistic Internet setups -- and efficient CMT usage on such paths is therefore crucial. In this paper, we first show the challenges of plain as well as RP-aware CMT data transport over asymmetric paths. After that, we introduce mechanisms for efficient transport over such paths. Finally, we analyse the performance of our approaches by using simulations.
