Design and Implementation of 1588 time synchronization technology base on FlexE
Abstract:In order to meet the 5g bearing network requirements of large capacity and network section, FlexE (flexible Ethernet) is expected to be as an important technology has been widely used in communication network ,At the same time,1588 time synchronization technology is also expected to become an important synchronous mode of 5G communication.How to achieve 1588 time synchronization on the basis of FlexE is the primary content of this study, this paper describes the basic principle of 1588 time synchronization and the transmission way of PTP message in FlexE interface, and proposes a design scheme based on FlexE to realize 1588 synchronization technology. The experimental results show that this scheme can realize the synchronous function of 1588 and has high synchronization accuracy and stability.
