Abstract

The invention relates to a flow generation device capable of realizing software defined routing based on SDN (software defined networking) technologies and belongs to the communication technological field. The network architecture of the flow generation device includes a management plane, a control plane and a data plane, wherein the management plane is connected with the control plane and defines flow according to user demands, and defines routing strategies for transmission of generated flow at an external network, the control plane is responsible for connecting the data plane and external network equipment, and pushing control commands to the data plane and configuring routing strategies at the external network, and the data plane is mainly responsible for generating network data flow. With the flow generation device adopted, network state information is monitored and analyzed in real time in a simulation flow generation process, and users can define flow and configure routing schemes for the transmission of the flow in the external network according to the their own needs; and at the same time, an automatic mode is enabled when the users do not configure flow routing, and proper transmission paths can be selected independently according to network conditions.

Description

technical field [0001] The invention belongs to the field of communications, and in particular relates to a traffic generating device for realizing software-defined routing based on SDN technology. Background technique [0002] Internet innovation is a cutting-edge and highly experimental field, and relevant research results will be widely accepted and used only after they have been verified by practice. Therefore, researchers need network test beds to verify new network architectures, protocols, services, etc. As the key equipment of the network test bed, the traffic generator is mainly used to generate simulated network traffic and simulate the possible network conditions after the actual deployment of the network. The effectiveness and convenience of its functions are of great significance to the experimental deployment. [0003] Currently, there are two main methods for generating traffic: 1. Network traffic playback—use a network sniffer to sniff the network and record...
