Problems solved by technology

[0004] In the above method, all the messages of the data center need to be processed by the ED of the data center, and the processing pressure of the ED is relatively high. Once the ED fails, it will directly cause the data centers to be unable to interconnect.

Abstract

The invention provides a message transmission method and device. The message transmission method includes the steps that through a destination address querying and forwarding table of a received datamessage, a corresponding output interface is obtained; if the output interface is a first tunnel, through a destination address querying and routing table of the first tunnel, at least two corresponding routes are obtained; a source address of the first tunnel is a group address of a first device group, and a destination address of the first tunnel is a group address of a second device group; oneroute is selected from the routes, and the data message is sent to a second ED corresponding to the selected route, so that the second ED sends the data message to a destination host computer. By adopting the message transmission method and device, load sharing of flow can be achieved on at least two EDs, flow balancing is achieved, processing pressure of each ED is reduced, and the reliability ofED processing is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message transmission method and device. Background technique [0002] EVPN (Ethernet Virtual Private Network, Ethernet Virtual Private Network) is a Layer 2 VPN (Virtual Private Network, Virtual Private Network) technology, and the control plane adopts MP-BGP (MultiProtocol-Border Gateway Protocol, Multi-Protocol-Border Gateway Protocol) notification For routing information, the data plane adopts VXLAN (Virtual eXtensible Local Area Network, extensible virtual local area network) encapsulation method to forward packets. Among them, VXLAN is a layer-2 VPN technology based on IP network and adopts "MAC (Media Access Control, Media Access Control) inUDP (User Datagram Protocol, User Datagram Protocol)" encapsulation form. VXLAN can provide Provider or enterprise IP network, provide Layer 2 interconnection for scattered sites, and provide business isolation fo...
