摘要

为应对未来移动网络所面临的巨大挑战，业界提出了自适应比特流（adaptive bit rate，ABR）技术和移动边缘计算（mobile edge computing，MEC），旨在为用户提供高体验质量、低时延、高带宽和多样化的服务。联合ABR和MEC来优化视频内容分发，对于提高网络性能和用户体验质量具有重要意义。其中，各项网络资源的联合优化是重要的研究课题。首先对MEC进行了概述，然后基于面向自适应流的MEC缓存转码联合优化问题，对业界已有工作进行了分析和对比，并对未来面临的挑战和研究难点进行了归纳和展望。

Abstract

To deal with the huge challenges in futuremobile networks

the industry has proposed adaptive bit rate(ABR)technology andmobile edge computing(MEC)

aiming to provide users with diverse services of high quality of experience

low latency and high bandwidth.Combining ABR and MEC to optimize the distribution of video content has been quite important for improving network performance and quality of experience.Especially

the joint optimization of network resources has arisen as an essential research topic.An overview of MEC was firstly given

and then the existing work in the industry on the joint optimization problem of MEC caching and transcoding oriented to adaptive streaming was analyzed and compared.Finally

the existing challenges in the future were summarized.
