Problems solved by technology

[0006] However, when there are a large number of hosts, due to the limited specifications of the MAC forwarding table, if the storage space of the MAC forwarding table is full, it will not be possible to store the MAC forwarding table entries of all hosts, resulting in abnormal message transmission
Moreover, if the MAC addresses of different hosts conflict, it will also cause abnormal packet transmission.

Abstract

The present disclosure provides a message transmission method, device, and machine-readable storage medium. The method includes: after receiving a message through a first interface, determining a specific tag corresponding to the message; determining a specific tag corresponding to the specific tag Corresponding VXLAN tunnel; send the packet carrying the specific tag to the second device through the VXLAN tunnel, so that the second device determines the second interface corresponding to the specific tag, and sends the packet through the second interface arts. Through the technical solution of the present disclosure, message transmission can be realized through a specific mark, without relying on the learning and forwarding of MAC addresses, thereby greatly reducing the pressure of table lookup and forwarding of devices, reducing the possibility of message transmission errors, and avoiding MAC forwarding tables Abnormal packet transmission caused by the full storage space and MAC address conflicts of different hosts.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a message transmission method, device and machine-readable storage medium. Background technique [0002] VXLAN (Virtual eXtensible Local Area Network, scalable virtual local area network) is based on IP network, using "MAC (Media Access Control, Media Access Control) in UDP (User Datagram Protocol, User Datagram Protocol)" encapsulation form of two-layer VPN ( Virtual Private Network, virtual private network) technology. Based on the existing service provider or enterprise IP network, VXLAN can provide Layer 2 interconnection for scattered sites and provide service isolation for different tenants. [0003] In VXLAN, the message is usually transmitted based on the destination MAC address of the message. For example, VTEP (VXLAN Tunnel End Point, VXLAN tunnel end point) learns the following MAC forwarding table. After receiving the message with the destination M...
