The fast growth of video streaming is responsible for a huge amount of traffic over the past few years. Because of the variety of video content on the Internet, a potential market is emerging for video providers. However, a rapid increase in video traffic and users poses challenges for network operators maintaining user expectation. To address this problem, network operators need a mechanism to monitor the quality of experience (QoE) perceived by the user. This allows reacting to quality degradation to improve the service. With the paradigm of network function virtualization, network operators are able to deploy such a video monitoring function in the cloud. In this work, we investigate the feasibility of deploying a virtual network function (VNF) for video buffer and QoE monitoring on the Amazon Web Service cloud.

VNF部署对云中QoE监控的影响

在过去的几年中，视频流的快速增长导致了大量的流量。由于Internet上视频内容的多样性，视频提供商的潜在市场正在涌现。但是，视频流量和用户的快速增加给网络运营商保持用户期望带来了挑战。为了解决此问题，网络运营商需要一种机制来监视用户感知的体验质量（QoE）。这允许对质量下降做出反应以改善服务。利用网络功能虚拟化的范例，网络运营商能够在云中部署这种视频监控功能。在这项工作中，我们研究了在亚马逊网络服务云上为视频缓冲区和QoE监控部署虚拟网络功能（VNF）的可行性。
