As an essential part of NANOG conferences, our hackathons are designed to be both fun and engaging, as well as to provide a platform that builds community and fosters greater networking and programming knowledge. The NANOG Hackathons are hands-on and educational at their core — directly supporting the most critical aspects of our mission, so all levels are welcome to participate, and registration is free.
The NANOG 90 Hackathon will focus on Problem Solving/Troubleshooting competitions.

Different layered timing solutions in datacenters are presented. This will showcase different architectures which leverage multiple technologies including the OCP-TAP Timecard, COTS Global navigation satellite system (GNSS): A general term describing any satellite constellation that provides positioning, navigation, and timing (PNT) services on a global or regional basis. See also time servers, Pulse Per Second distribution units, NTP, or Network Time Protocol, is a widely used networking protocol that enables computers and devices to synchronize their system clocks with a reference time source. It ensures accurate timekeeping in computer networks by allowing devices to obtain precise time information from NTP servers, which are typically synchronized to highly accurate atomic clocks. NTP is essential for various applications and services that rely on synchronized time, such as network security, authentication, and data logging., Precision Time Protocol is a protocol used to synchronize clocks throughout a computer network. On a LAN network, PTP can enable the clocks on each server to be synchronized within a sub-microsecond range, thus making it suitable for demanding applications that require precise timing and control. PTP is standardized within IEEE-1588v2. and PTP High Accuracy profile (White-Rabbit) in the core of the datacenter while discussing its advantages and disadvantages. Depending on the required end-to-end time error budget, synchronization accuracy of nodes can be less accurate using protocols intended to work with massive layers. Alternatively, the synchronization of key nodes with higher accuracy might be leveraged to trace timing performance and improve resiliency.
Higher level of accuracy can be used in specific segments of the datacenter hosting highly time sensitive applications such as financial services. Tight relative timing between monitoring units through an accurately synchronized visibility network facilitates detailed analysis of the timing across the whole datacenter.
Francisco (Paco) Girela: Francisco is the BizDev and Sales Engineering Lead at Safran. He holds a Ph.D. in Telecommunications Engineering from the University of Granada. After some time in the private sector, Francisco joined the Timing Keepers group at the same university as a researcher. During his research, he specialized in ultra-accurate time transfer systems, and he focused on the development of the White Rabbit technology. At the moment, he leads the expansion of White Rabbit time sync in the Americas. His latest work involves the deployment of very long distance WR links, the integration of White Rabbit core in third party Field-Programming Gate Array: an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence the term field-programmable.
