ECO:5G应用的边缘云优化

ECO: Edge-Cloud Optimization of 5G applications

Kunal Rao, Giuseppe Coviello, Wang-Pin Hsiung, Srimat Chakradhar

摘要:

具有100毫秒以上网络延迟的集中式云计算无法满足自动驾驶、智能制造、触觉互联网和增强或虚拟现实等新兴5G应用所需的数十毫秒至亚毫秒的响应时间。我们描述了一种新的动态运行时,使这些应用程序能够始终有效地利用5G网络,在该网络的边缘进行计算,以及集中式云中的资源。我们的运行时持续监控微服务之间的交互,估计微服务之间产生和交换的数据,并使用一种新的图最小割算法将微服务动态映射到边缘或云,以满足特定于应用程序的响应时间。我们的运行时还处理临时网络分区,并通过使用微服务代理将WAN带宽降低一个数量级来维护分布式结构中的数据一致性,所有这些都是通过利用有关应用程序功能、延迟关键管道和中间数据的知识以{ \it应用程序特定的方式}进行的。我们通过成功地将两个复杂的、有代表性的现实世界视频分析应用程序映射到AWS/Verizon Wavelength边缘云架构来说明我们的运行时的使用,并将应用程序的响应时间与静态边缘云实现相比提高了2倍。

英文摘要:

Centralized cloud computing with 100+ milliseconds network latencies cannot meet the tens of milliseconds to sub-millisecond response times required for emerging 5G applications like autonomous driving, smart manufacturing, tactile internet, and augmented or virtual reality. We describe a new, dynamic runtime that enables such applications to make effective use of a 5G network, computing at the edge of this network, and resources in the centralized cloud, at all times. Our runtime continuously monitors the interaction among the microservices, estimates the data produced and exchanged among the microservices, and uses a novel graph min-cut algorithm to dynamically map the microservices to the edge or the cloud to satisfy application-specific response times. Our runtime also handles temporary network partitions, and maintains data consistency across the distributed fabric by using microservice proxies to reduce WAN bandwidth by an order of magnitude, all in an {\it application-specific manner} by leveraging knowledge about the application's functions, latency-critical pipelines and intermediate data. We illustrate the use of our runtime by successfully mapping two complex, representative real-world video analytics applications to the AWS/Verizon Wavelength edge-cloud architecture, and improving application response times by 2x when compared with a static edge-cloud implementation.
