Time Synchronization Class D Clock Chaining - EANTC Multi-Vendor Interop Showcase at MPLS SDN 2024

Time synchronization of telecom networks needs to be extremely precise for some use case scenarios. Today, so-called "Class C" clocks in routers are sufficient for common 5G scenarios, but in the future, "Class D" clocks will be required for 6G and more advanced mobile and other use cases. Network-wide precision of less than 50 ns time interval error must be reached. Clock precision must be maintained even if multiple boundary clocks (regenerating the signal from a grandmaster clock) are sequentially chained. Such a scenario is not unusual in large networks. As a technology viability demonstration, EANTC and ten vendors (Arista, Calnex, Ciena, Cisco, Ericsson, H3C, Huawei, Juniper, Keysight, and ZTE) successfully validated a chain of nine Class C and Class D boundary clocks to provide synchronization within the standards-required precision. The G.8275.1 telecom profile with enhanced SyncE was used. The speakers in this session include: Neil Jackson, Calnex Dennis Hagarty, Cisco Bjørnar Forthun, Juniper Liu Guangfeng (Felix), H3C Sayantan Pramanick, Keysight The full test report can be downloaded free of charge from https://eantc.de/events/mpls-sdn-inte...
