Construction method of SDN virtual network environment and SDN virtual network environment

Abstract

The invention discloses a construction method of a SDN virtual network environment and the SDN virtual network environment. The construction method comprises establishing of a virtual node and a virtual link. The virtual node is obtained by performing virtual construction according to equipment having different network functions. The virtual node is a virtual controller, a virtual switch or a virtual host. The virtual link is obtained by performing virtual construction according to the communication mode between different sets of equipment. The corresponding virtual network elements are constructed for the target network environment: firstly virtual construction of the virtual node is performed, and the virtual node is corresponding to the equipment in the target network environment; thenthe virtual link is constructed, and the virtual link is corresponding to equipment communication in the target environment; and finally the virtual network experimental environment corresponding to the target network environment is obtained. The network element function is abstracted, and network element construction of the SDN is performed by introducing the concept of the virtual network element so that the SDN mobility and reconfigurability can be greatly enhanced, and adaptation of different network experimental environments can be realized.

Description

technical field [0001] The invention belongs to the technical field of SDN network environment construction; in particular, it relates to a method for constructing an SDN virtual network environment and the SDN virtual network environment. Background technique [0002] The types and requirements of application services have become increasingly complex and diversified in the gradual integration of Internet technology and traditional industries, especially new business and application scenarios require continuously improved service quality to adapt to them. In this context, the TCP / IP-based distributed traditional Internet, which was designed only with network connectivity in mind, has exposed more and more shortcomings. In order to solve these deficiencies, many new algorithms, protocols and network structures have been designed and proposed by researchers. However, in order to obtain reliable experimental data to provide support for the application of these network innovati...

Problems solved by technology

In a traditional network, since each router or switch has its own control and forwarding logic running, virtualizing these devices involves distributed operations, which will be more complicated.

[0004] The deployment of the traditional TCP / IP-based network architecture mainly relies on some dedicated hardware devices. However, such a deployment solution has the disadvantages of fixed functions that cannot meet the requirements of innovative implementation and requires a large amount of capital investment.

At the same time, the tight coupling between the network environment and physical hardware leads to the impossibility of complex network scenarios and efficient resource reuse
