Problems solved by technology

[0007] Even Openflow's abstraction of traditional routing has some disadvantages: network programmers must understand the details of the underlying network devices
The whole process is very complicated and not easy for network administrators, let alone network application developers

Abstract

The present invention provides a method and device of network function abstraction realization in a software definition network. The method comprises: defining a network function extraction description model based on a rule structure, based on the network function abstraction description model, allowing the controller to perform explanation of the customized network and generate the configuration script supported by a bottom layer network device, such as: a flow table item according with an Openflow protocol specification, and allowing the controller to send the generated device configuration script down to the bottom layer network device through a related control protocol (such as the Openflow protocol). Therefore, the method and device of network function abstraction in the software definition network can shield the complexity and the diversity of the network device and the network function, only need to create abstracted network function rule entry to indicate the target network function, the executed object and the execution action high-level description with no need for understanding the details of the bottom network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a Software Defined Networking . Background technique [0002] SDN (Software Defined Networking) is an emerging network architecture with features such as flexibility and manageability, and is more adaptable to current network application upgrades and frequent changes. SDN separates control from forwarding and supports programming of the network. How to enable network programmability ？ Network abstraction is regarded as an effective way. The network functions originally undertaken by the underlying network elements will be abstracted and replaced and realized by a series of unified and configurable action sets. For example, we can regard the Openflow protocol as an abstraction of traditional routing and forwarding functions. A series of flow table entries are delivered and configured to the switch router. These flow table entries can perform the same function a...
