Problems solved by technology

[0003] Due to the explosive growth of the virtual machine scale supported by the data center, and the logical isolation between different tenants in the second layer domain, and because the traditional VLAN (Virtual Local Area Network, Virtual Local Area Network) only supports a maximum of 4096, therefore, When using VLANs to divide and isolate Layer 2 domains, the number and scale are far from meeting the needs

Abstract

The present invention provides a message transmission method and device. The method includes: receiving a message from a virtual switch; obtaining the forwarding priority corresponding to the message; generating a control flow table corresponding to the message, and the control flow table is used for Encapsulate the packet matching the control flow table of the specified type, and add the forwarding priority to the packet of the specified type encapsulation; send the control flow table to the virtual switch, so that the virtual switch can use the The control flow table sends packets. Through the technical solution of the present invention, the forwarding priority of the virtual machine can be divided according to the tenant type and / or service type corresponding to the virtual machine, and the forwarding priority can be carried in the message, so that the message can be transmitted according to the forwarding priority. This ensures that packets of important services of important tenants are transmitted preferentially in the network and improves user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a message transmission method and device. Background technique [0002] At present, the data center solution can usually be a network constructed by SDN (Software Defined Network, software-defined network) + VXLAN (Virtual eXtensible Local Area Network, scalable virtual local area network). Among them, SDN is a new type of network architecture. Its core idea is to separate the control plane and forwarding plane of network equipment, and to centralize and flexibly control network traffic through controllers (such as SDN controllers), so as to provide core network and application Provide a good platform for innovation. [0003] Due to the explosive growth of the virtual machine size supported by the data center, and the logical isolation between different tenants in the second layer domain, and because the traditional VLAN (Virtual Local Area Network, Virtual Local ...
