Abstract
The invention relates to the clock synchronization field of communication technologies, and discloses an FC network based clock synchronization precision testing device and method. The clock synchronization precision testing device comprises a clock server; and multiple clock clients respectively connected with an FC switch and respectively used for sending and receiving SYNx, SYNy and SYNz clock synchronization primitives. The FC network based clock synchronization precision testing method comprises the steps of recording time points when the clock server sends the SYNx, SYNy and SYNz clock synchronization primitives and clock synchronization primitive values; recording time points when each clock client receives the SYNx, SYNy and SYNz clock synchronization primitives and the clock synchronization primitive values; and calculating clock synchronization precision of each port and judging whether the clock synchronization precision is satisfied with a requirement. According to the FC network based clock synchronization precision testing device and method, the clock synchronization precision of the FC switch can be tested in real time without manual intervention, the testing intensity is high, and the testing result is reliable; and hardware logic is liable to realize, and a nanosecond-level precision test for clock synchronization of an FC switching network can be carried out.
