Title: CROSS-REGIONAL DATA TRANSMISSION
Abstract:
The present disclosure is directed to a cross-regional data transmission method and device. Metadata information sent by a corresponding client device is acquired, and the metadata information is sent to a corresponding metadata transmission node device, wherein the metadata information includes data replication progress information of the corresponding client device; to-be-forwarded data information sent by the corresponding metadata transmission node device is acquired, and the to-be-forwarded data information is pushed to the corresponding client device, wherein the to-be-forwarded data information includes data replication progress information of another client device, so that the metadata information sent by the corresponding client device is effectively sent to the corresponding metadata transmission node device; and the acquired to-be-forwarded data information sent by the corresponding metadata transmission node device is pushed to the corresponding client device, to achieve synchronization of the metadata information.
