Abstract
A method for migrating a service of a data center is disclosed. When an active data center is faulty, a tunnel processing device disables a locally-saved tunnel entry of a server in the active data center. After receiving a service access request packet from a customer edge router, the tunnel processing device acquires an IP address of a tunnel processing module deployed on a server in a standby data center according to an IP address of a destination virtual machine, encapsulates the service access request packet and routes the encapsulated packet to the tunnel processing module, so as to migrate a data center service from the active data center to the standby data center.
