Problems solved by technology
However, its graphical program is relatively simple, and its operation is unstable. It needs to use the command line, and the constructed network is relatively abstract.
At the same time, it cannot detect the network operation status and network data in real time according to the environment and make adaptive adjustments. The required experimental data can only be measured indirectly, which increases the complexity of the experiment.

The invention provides an adaptive SDN simulation system and simulation platform based on task driving. The system comprises a graphical control platform, a controller module and a virtual network environment. In the adaptive SDN simulation system provided by the invention, the controller module and the graphical control platform are separated and are respectively run in different virtual machines, the graphical control platform calls the controller module through an RPC and uses Json to transmit data; and the calling of other modules is to submit a request to related pages via GET and POST toobtain data, and the data are set or displayed in the graphical control platform. The control platform generates setting messages by capturing various configuration information set by a user based ontask requirements, and sends the setting messages to the controller to stimulate the network to perform adaptive adjustment.
Description
technical field [0001] The invention belongs to the technical field of SDN simulation, in particular to a task-driven adaptive SDN simulation system and a simulation platform. Background technique [0002] OpenDaylight (ODL) is a modular, scalable, upgradable, and multi-protocol controller framework developed based on SDN, mainly including Switch Manager, Statistics Manager, Topology Manager, Forwarding Rule Manager, ARP Manager and other modules, which can control The network devices it manages are managed and configured in a unified manner. In view of the fact that SDN equipment is relatively expensive and the cost of networking is too high, most of the current research based on SDN is based on Mininet. [0003] Mininet is a lightweight SDN and testing platform. It can complete the operation of the kernel system and user code required to simulate a complete network with a single system, supports OpenFlow, OpenvSwith and other related protocols, and is helpful for interac...
