Abstract: Embodiments of the present invention provide a clock synchronization method and device. The method includes: receiving, a preconfigured multi-protocol label switching (MPLS) capability parameter and a traffic engineering (TE) capability parameter, and establishing, based on the MPLS capability parameter and the TE capability parameter, an MPLS tunnel interface; establishing, an MPLS TE tunnel whose bidirectional paths are consistent between the first clock synchronization device and a second clock synchronization device; and performing, clock synchronization message interaction with the second clock synchronization device through the established MPLS TE tunnel. In the embodiments of the present invention, by establishing the MPLS TE tunnel whose bidirectional paths are consistent between the first clock synchronization device and the second clock synchronization device which perform clock synchronization message interaction, symmetry of clock synchronization message interaction paths is ensured, and therefore, a time error in clock synchronization resulting from asymmetry of the paths is avoided.

Abstract: A computer device, a system, and a load balancing method are provided. A load balancing virtual machine is created on the computer device. When load balancing processing needs to be performed on a service of a virtual machine of the computer device, a related service packet is sent to the load balancing virtual machine of the computer device, so as to perform load balancing processing, thereby avoiding a processing delay caused by congestion of centralized load balancing. In addition, when a computer device is faulty, a virtual machine of the computer device goes offline accordingly, and a load balancing requirement is not generated any more. Therefore, when a fault of a single computer device causes a fault of a load balancing virtual machine, there is no service interruption that is caused by active/standby switchover because of the fault of the load balancing virtual machine.
