Title: METHOD OF INTERCONNECTING CLOUD DATA CENTERS, AND DEVICE
Abstract:
The disclosure discloses a method of interconnecting cloud data centers, and a device. The method comprises: establishing a BGP neighbor relationship between a local cloud data center and a cloud data center to be communicated; obtaining, from the cloud data center to be communicated, MAC information, and establishing a tunnel; identifying the MAC information, obtaining port information of the local cloud data center, and combining both the information to generate a forwarding table for communication between a gateway apparatus at the local cloud data center and a gateway apparatus at the cloud data center to be communicated; and transmitting, to the gateway apparatus at the local cloud data center, the forwarding table, to enable, according to the established tunnel and the obtained forwarding table, communication between the gateway apparatus at the local cloud data center and the gateway apparatus at the cloud data center to be communicated. The method of interconnecting cloud data centers as disclosed in the disclosure achieves the effect of loose coupling or no coupling between apparatuses at cloud data centers, and implements interconnection between apparatus utilizing different specifications at cloud data centers without employing any private protocol, enhancing applicability of the method of interconnecting cloud data centers.
