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 invention provides a message transmission method and device and a machine readable memory medium. The method comprises the steps of determining a specific mark corresponding to a message after themessage is received through a first interface; determining a VXLAN (Virtual Extensible Local Area Network) tunnel corresponding to the specific mark; and sending a message carrying out the specific mark to a second device through the VXLAN tunnel, thereby enabling the second device to determine a second interface corresponding to the specific mark and send the message through the second interface. Through application of the technical scheme provided by the invention, the message is transmitted through the specific mark, without depending on MAC (Media Access Control) learning and forwarding,so the table look-up forwarding pressure of the device is greatly reduced, the message transmission error occurring possibility is reduced, the message transmission abnormity problem resulting from the condition that the memory space of an MAC forwarding table is occupied fully and MAC addresses of different hosts conflict is avoided.

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...
