Abstract
Embodiments of the present invention provide a method, an apparatus, and a system for performing time synchronization on PCIE (PCI Express, peripheral component interconnect express) devices. The method mainly includes: a PCIE device receiving, through a hardware interface, a time synchronization signal sent from a clock source device; parsing, by the PCIE device, the time synchronization signal to obtain clock information carried in the time synchronization signal, and using the clock information as a clock of the PCIE device. The PCIE devices are supported to access a synchronous network, and the PCIE devices are supported to be used as a global clock source.
