Abstract: This application discloses a clock synchronization method and a related apparatus in a distributed system. The distributed system includes a plurality of nodes, and the plurality of nodes include a master node and a plurality of slave nodes. The master node obtains a plurality of local clock offsets, where each of the plurality of local clock offsets indicates a clock offset between two nodes in the distributed system. The master node determines a global clock offset of a target slave node relative to the master node based on the plurality of local clock offsets, and sends the global clock offset to the target slave node. The target slave node obtains a clock reference value of a local clock, and then performs clock synchronization based on the clock reference value and the global clock offset.

Abstract: A method for processing customer requests includes: generating a service request according to a business subscribed by a customer, wherein the service request carries service request information; acquiring business attribute information required in business processing corresponding to the service request, according to the service request information; and determining a corresponding business processing unit according to the acquired business attribute information, so as to process the subscribed business. A system for processing customer requests is also disclosed. With the present invention, the quality of service may be guaranteed and the satisfaction degree of the customer may be improved.
