SUMMARY:Lightning Talk: Performance Profile Estimation for Emulated Multi-
 Site Federations
DESCRIPTION:Workshop\n\nLightning Talk: Performance Profile Estimation for
  Emulated Multi-Site Federations\n\nImam\n\nEmulations that replicate the 
 software environments of multi-site federations of computing systems and i
 nstruments have been developed to reduce the cost and disruptions to physi
 cal, production infrastructures. These emulation environments have been ef
 fectively used to develop and test software modules for various tasks incl
 uding container orchestration and instrument access. For performance asses
 sment, however, the emulated frameworks are severely limited in providing 
 accurate network and IO measurements at 10 Gbps and higher data rates. The
  data transfer performance profiles estimated using these measurements are
  usually inaccurate for high bandwidth and high latency connections, since
  they do not accurately reflect the critical network transport dynamics. W
 e utilize measurements from a physical testbed with hardware network emula
 tors to obtain throughput profiles for emulated federations that closely m
 atch the expected profiles. Using a four-site federation scenario emulatio
 n, we show the effectiveness of this approach in providing accurate concav
 e throughput profiles from an inaccurate convex one indicated by Mininet e
 mulation.\n\nTag: Big Data, Cloud and Distributed Computing, Data Analytic
