CERN大型强子对撞机(LHC)的紧凑型μ子螺线管(CMS)实验通过利用各种各样的国家研究和教育网络(NREN)来分发其数据,CMS被迫将其视为不透明的资源。因此,CMS看到了高度可变的性能,这已经对协调地球仪周围PB移动的运营商构成了挑战。然而,这种不可预测性威胁着CMS的后勤噩梦,因为它将在2030年进入高亮度LHC(HL-LHC)时代,预计每年将产生大约0.5艾字节的数据。本文探讨了一种潜在的解决方案:软件定义网络(SDN)。特别是,SENSE,由能源科学网络开发的SDN产品,与Rucio,LHC使用的数据管理软件的原型互操作,概述。此外,本文介绍了目前的进展,把这些技术结合在一起。
The Compact Muon Solenoid (CMS) experiment at the CERN Large Hadron Collider (LHC) distributes its data by leveraging a diverse array of National Research and Education Networks (NRENs), which CMS is forced to treat as an opaque resource. Consequently, CMS sees highly variable performance that already poses a challenge for operators coordinating the movement of petabytes around the globe. This kind of unpredictability, however, threatens CMS with a logistical nightmare as it barrels towards the High Luminosity LHC (HL-LHC) era in 2030, which is expected to produce roughly 0.5 exabytes of data per year. This paper explores one potential solution to this issue: software-defined networking (SDN). In particular, the prototypical interoperation of SENSE, an SDN product developed by the Energy Sciences Network, with Rucio, the data management software used by the LHC, is outlined. In addition, this paper presents the current progress in bringing these technologies together.
