远程医疗、智能家电和智能能源等物联网（IoT）应用在家庭中变得越来越普遍。但是，它们必须与传统应用（如视频流、视频会议和批量文件传输）争夺带宽。当家庭网关使用传统的先进先出（FIFO）队列管理时，这种竞争可能对物联网应用不利。简单地增加家庭网关和互联网服务提供商（ISP）之间的带宽，即使在可能的情况下，也不能保证物联网应用的带宽，因为许多传统应用将消耗尽可能多的带宽。在本文中，我们将探讨目前在家庭网关中实施的主动队列管理（AQM）是否可以为物联网流量提供保护。我们调查的效果，不同的AQM算法部署在家庭网关中的多个并发应用程序流的场景。我们发现，在家庭网关处部署多队列FlowQueue Controlled Delay（CQ-CoDel）或混合FlowQueue Proportional Integral Controller Enhanced（CQ-PIE）可以在物联网流和其他应用的吞吐量和排队延迟方面提供出色的容量共享、流隔离和良好的保护，这是传统FIFO或其他单队列AQM（如Proportional Integral Controller Enhanced（PIE））无法实现的。
Internet of Things (IoT) applications such as telehealth, smart appliances, and smart energy are becoming more common within the home. However, they must compete for bandwidth with traditional applications such as video streaming, video conferencing, and bulk file transfers. Such competition can be detrimental to the IoT applications when home gateways use traditional first-in-first-out (FIFO) queue management. Simply increasing bandwidth between the home gateway and the Internet Service Provider (ISP), even when possible, provides no guarantee of bandwidth for IoT applications since many traditional applications will consume as much bandwidth as is available. In this paper, we explore whether active queue management (AQM), now being implemented in home gateways, can provide protection for IoT flows. We investigate the effect of different AQM algorithms deployed at the home gateway in scenarios with multiple concurrent application flows. We find that deploying multiqueue FlowQueue Controlled Delay (FQ-CoDel) or the hybrid FlowQueue Proportional Integral Controller Enhanced (FQ-PIE) at the home gateway can provide excellent capacity sharing, flow isolation, and good protection in terms of throughput and queuing delays for IoT flows and other applications, which cannot be achieved with traditional FIFO or other single-queue AQMs such as Proportional Integral Controller Enhanced (PIE).
