Editing Clock synchronization (section)

===Huygens===
Researchers from Stanford and Google introduced Huygens, a probe-based, end-to-end clock synchronization algorithm. Huygens is implemented in software and thus can be deployed in [[data center]]s or in [[public cloud]] environments. By leveraging some key aspects of modern data centers and applying novel estimation algorithms and signal processing techniques, the Huygens algorithm achieved an accuracy of tens of nanoseconds even at high network load.<ref>{{cite book |url=https://www.usenix.org/conference/nsdi18/presentation/geng |title=Exploiting a Natural Network Effect for Scalable, Fine-grained Clock Synchronization|year=2018|pages=81–94|isbn=9781939133014}}</ref> The findings of this research are being tested in financial market applications.<ref>{{cite news |url=https://www.nytimes.com/2018/06/29/technology/computer-networks-speed-nasdaq.html |title=Time Split to the Nanosecond Is Precisely What Wall Street Wants |author=John Markoff |date=June 29, 2018 |work=New York Times}}</ref>
