论文摘要
移动网络运营商（MNOS）正在研究经济上可行的回程解决方案作为纤维的替代方案，特别是混合纤维同轴网络（HFC）。当将无线和HFC网络的潜伏期添加在一起时，结果是明显的端到端系统潜伏期，尤其是在网络拥塞下。为了减少总系统延迟，我们提出了一种方法，通过在以前的论文中协调LTE和HFC调度来改善上游用户核心潜伏期。在本文中，我们在自定义LTE和DOCSIS端到端系统测试台上实施并优化了所提出的方法。 TestBED与Cisco的宽带路由器CBR-8一起使用OpenAirInterface（OAI）平台，该平台目前部署在世界各地的HFC网络中。我们的结果表明，在所有交通负荷条件下，进行了回程延迟的改善。
The mobile network operators (MNOs) are looking into economically viable backhaul solutions as alternatives to fiber, specifically the hybrid fiber coaxial networks (HFC). When the latencies from both the wireless and the HFC networks are added together, the result is a noticeable end-to-end system latency, particularly under network congestion. In order to decrease total system latency, we proposed a method to improve upstream user- to-mobile core latency by coordinating the LTE and HFC scheduling in previous papers. In this paper, we implement and optimize the proposed method on a custom LTE and DOCSIS end-to-end system testbed. The testbed uses the OpenAirInterface (OAI) platform for the LTE network, along with Cisco's broadband router cBR-8 that is currently deployed in the HFC networks around the world. Our results show a backhaul latency improvement under all traffic load conditions.
