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.

Abstract translation: 公开了一种用于迁移数据中心的服务的方法。 当活动数据中心发生故障时，隧道处理设备将禁用活动数据中心服务器的本地保存的隧道条目。 隧道处理设备从客户边缘路由器接收到业务接入请求报文后，根据目的虚拟机的IP地址获取部署在备用数据中心的服务器上的隧道处理模块的IP地址，封装业务接入 请求分组并将封装的分组路由到隧道处理模块，以便将数据中心服务从活动数据中心迁移到备用数据中心。
