Abstract

The application discloses a data center communication method, device and system, which relate to the field of communication networks and are used to solve the technical problem of poor reliability of the data center. The method includes: detecting the failure of the egress gateway of the first data center, sending the first VRRP protocol message to the edge switch of the second data center; receiving the second VRRP from the egress gateway of the second data center forwarded by the edge switch of the second data center protocol message; learn the MAC address of the second data center egress gateway according to the second VRRP protocol message to establish a MAC forwarding table; establish the communication channel between the second data center egress gateway and the first data center host through the MAC forwarding table, wherein, the first A data center edge switch respectively establishes layer 2 connections with the first data center egress gateway and the second data center edge switch, the first data center edge switch, the first data center egress gateway, the second data center edge switch, and the second data center The egress gateways are in the same VRRP group.

Description

technical field [0001] The present application relates to the technical field of data communication, and in particular to a communication method, device and system for a data center. Background technique [0002] in such as figure 1 In the data center shown, in order to play the role of disaster backup, it usually includes two data centers A and B with different physical locations, and each data center can respond to external data through its own gateway (gateway A or gateway B). network access request. In order to solve the business and data backup requirements between data center A and data center B, it is usually necessary to set up a scalable virtual local area network (Virtual eXtensible Local Area Network, VXLAN) between data center A and data center B, so that data center A Form a two-layer network with data center B, and the service access between data center A and data center B is like in the same local area network, so that the gateways of data center A and data ...
