He is an expert at Ericsson Research working on synchronization and transport solutions. He is currently an active contributor to ITU-T SG15 Q13 (serving as rapporteur) and other relevant synchronization standardization bodies, as well as serving as the chair of the International Timing and Sync Forum (ITSF).

5 Ruffini holds a in telecommunication engineering from Sapienza University of Rome, 802 Plenary Tutorial on synchronization : a key Function in Time-Sensitive Networking and Beyond3/2/20217 Kishan Shenoireceived his bachelors, masters, and doctorate degrees from IIT-Delhi, Columbia University, and Stanford University, in 1972, 1973, and 1977, respectively. He is active in Standards development and active in the Steering Groups of WSTS and ITSF. He is named on 54 patents and has several publications including two books, Digital Signal Processing in Telecommunications (1995) and synchronization and Timing in Telecommunications (2009).

6 Dr. Shenoi is currently CTO of Qulsar, developing fit-for-purpose solutions for timing and Weiss worked at NIST from 1979, specializing in time transfer techniques and statistics of timing systems. Since January 2014 he is now a consultant on precision timing systems. Marc founded and has led WSTS annually since 1992, which is now a sister conference to the European version, the ITSF. In addition, Dr. Weiss led the NIST program to support GPS development from 1980 until his retirement in 2014. He has worked on and published Relativity issues as they relate to GPS and to primary frequency standards.

7 He has also specialized in Time-Scale Algorithms. He received his in Mathematical-Physics from the University of Colorado in Cosartis a Research Engineer with Microchip. A graduate of Stanford University, his R&D activities have included measurement algorithms and mathematical analysis for which he holds several patents. He serves on, as chair, contributor and editor, the ATIS and ITU-T committees responsible for network synchronization standardization. His TimeMonitorsoftware is used to collect and analyze synchronization and packet timing data and has been used in laboratories and networks throughout the Rodrigues works for Huawei as a Senior Engineer.

8 She holds an Electronic and Electrical Engineering degree from University of Campinas, is currently the associate rapporteur and editor of several recommendations at ITU-T SG15 Q13. She is a secretary of ieee 1588 WG and participates in ieee TSN WG.

9 IET enables seamless and secure connection of customer products across the entire landscape of Industrial IoT. Woods has 35 years of experience in the semiconductor industry. He is familiar with a variety of Ethernet-based Industrial protocols including Profinet, EtherNet/IP, as well as ieee TSN standards. He is also a voting member of the ieee 802 working group defining new Ethernet standards for Time Sensitive Networks and the editor of the IEC/ ieee 60802 Time-Sensitive Networking Profile for Industrial Automation. Max Turner holds a Diploma degree in Physics from the University of Ulm.

10 He joined BMW in Munich at the end of 2002 where he worked on MOST and FlexRay physical layer specifications. From 2005 to 2008 Max was working at the BMW Technology Office in Palo Alto, California where he focussed on DSRC based V2x communication around and IEEE1609. After his return to Munich he started the introduction of Ethernet into Autosar(SocketAdaptor) and became part of the team developing the Diagnostics over IP (ISO13400) specification. Max was part of the team introducing Ethernet ( SOME/IP and AVB) into BMW vehicles and was active in ieee and AVnuto foster automotive Ethernet adaptations.
