A business isolation method, device, SDN network system and routing equipment

Abstract

The present application relates to a service isolation method, device, SDN network system and routing equipment, belonging to the field of communication technology. The method is applied to the routing device in the SDN network, and the method includes: when receiving the GRE encapsulated message forwarded by the peer device through the pre-established tunnel, decapsulating the GRE encapsulated message and obtaining the key encapsulated in the GRE header The key value in the field; according to the preset corresponding relationship between the route identifier and the key value, search for the route identifier corresponding to the obtained key value, and forward the original packet obtained after decapsulation to the route identifier corresponding to the route The corresponding business interface. In the embodiment of the present application, by assigning different VRF labels to different application services, they are bound to the service interfaces corresponding to the application services, and the route identifiers in the different VRF labels are combined with the GRE header encapsulated in the outer layer of the tunnel. The key value in the department is associated with each other to achieve business isolation.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a service isolation method, device, SDN network system and routing equipment. Background technique [0002] With the development of cloud computing and related services, corresponding network resources also need to be adjusted in time according to changes in traffic patterns. However, the traditional network architecture model cannot adapt to this kind of flexible and changeable application. If the application continues to increase, the corresponding modification configuration and maintenance amount will increase greatly. The software-defined network (Software Defined Network, SDN) supports flexible software programming concepts, which can just meet the demand model of cloud computing, and will gradually replace traditional network deployment and become the mainstream. [0003] When multiple services need to be run in a wide area network (Wide Area Ne...
