Abstract

The invention provides an SDN-based satellite network management and control protocol semi-physical test device, which constructs a test device oriented to an SDN satellite network scene and used forwhole system simulation from user application to data physical transmission, and can provide an optimized network management and control scheme for a network decision maker. According to the device, an SDN centralized hierarchical management and control architecture is adopted, and a self-designed satellite network simulation system hardware deployment scheme and network management and control software are applied. The method has a reasonable human-computer interface, wherein a satellite transmission simulation system is constructed by using the SDN physical switch, and the designed virtual topology mechanism can quickly generate the satellite dynamic network topology in the wired network, so that the method has the advantages of being friendly to visualization, real and reliable in simulation result, quick in network scene construction and the like.

Description

technical field [0001] The invention relates to the field of aerospace communication, in particular to a semi-physical test device for an SDN-based satellite network management and control protocol. The device is used for the generation and hardware simulation of heterogeneous satellite network scenarios and the simulation of key network technologies for typical satellite tasks. The friendly human-computer interaction interface is convenient for users to realize custom satellite network scenarios and view test results. Background technique [0002] Software Defined Network (SDN), as a new network architecture that separates control and forwarding, has aroused great interest in applying SDN to spatial information networks due to its flexibility, openness and programmability. If technical research and verification are carried out in a real network system, not only the cycle is long and the cost is high, but also the normal operation of the existing satellite system may be affe...
