A network isolation method and device

Abstract

The invention provides a network isolation method and a network isolation device. The network isolation method comprises the steps of receiving a first message by first network accessing equipment, wherein the first message is transmitted from a physical server and carries label information, the physical server comprises a plurality of service bridges, different service bridges are connected with the first network accessing equipment through a physical network adapter of the physical server, and the label information is added by the service bridge which corresponds with the first message; determining second network accessing equipment which corresponds with a destination address by the first network accessing equipment when the label information matches the destination address that corresponds with the first message; and transmitting the first message to the second network accessing equipment by the first network accessing equipment through network core equipment so that the second network accessing equipment transmits the first message to the physical server which corresponds with the destination address, wherein the first network accessing equipment and the second network accessing equipment are connected with the network core equipment. The network isolation method and the network isolation device have advantages of realizing network isolation, reducing wiring difficulty and reducing network maintenance cost.

Description

Technical field [0001] The invention relates to the technical field of computer networks, in particular to a network isolation method and device. Background technique [0002] In a complex cloud computing environment, in order to meet various service requirements, the network carries multiple types of data traffic, such as virtual machine business traffic, virtual machine management traffic, physical machine management traffic, storage traffic, and so on. Considering network stability, the network is required to be isolated according to its importance and traffic type. [0003] In order to solve the problem of traffic isolation, the traditional approach in the industry is to build multiple physical networks to undertake business, management, and storage functions. By means of physical network isolation, a stable and secure lower-layer network environment is provided for the upper-layer cloud computing business. [0004] In order to realize the isolation of various business traffic,...
