论文摘要
在本文中，我们讨论了有关电缆服务界面规格（DOCSIS）网络的数据的移动回程延迟技术的延迟技术。当将无线和DOCSIS网络的潜伏期添加在一起时，它可能会导致明显的端到端系统潜伏期，尤其是在网络拥塞下。以前，我们提出了一种通过协调LTE和DOCSIS调度来改善上游用户对移动核心延迟的方法。该方法减少了DOCSIS网络的Request-Grant-DATA循环对系统潜伏期的影响，后者是Backhaul上游延迟的主要贡献者。由于该方法减少了DOCSIS数据路径的延迟，因此它将改善延迟敏感应用程序的性能，尤其是在将TCP用作运输方案时，尤其是当链接拥挤时。在本文中，我们研究了HARQ失败对系统性能的影响。通过仿真，我们表明，尽管LTE协议引入了不确定性，但协调调度可以改善整体系统延迟。
In this paper, we discuss latency reduction techniques for mobile backhaul over Data Over Cable Service Interface Specifications (DOCSIS) networks. When the latencies from both the wireless and the DOCSIS networks are added together, it can result in noticeable end-to-end system latency, particularly under network congestion. Previously, we proposed a method to improve upstream user-to-mobile core latency by coordinating the LTE and DOCSIS scheduling. The method reduces the impact on system latency from the DOCSIS network's request-grant-data loop, which is the main contributor of backhaul upstream latency. Since the method reduces latency on the DOCSIS data path, it will therefore improve performance of latency sensitive applications, particularly if TCP is used as the transport protocol, especially when the link is congested. In this paper, we investigate the effect of HARQ failure on system performance. Through simulation, we show that despite the uncertainty introduced by the LTE protocol, coordinated scheduling improves overall system latency.
