Description
Technical Field
The invention relates to a protocol testing method of a satellite communication simulation platform based on network virtualization, and belongs to the field of satellite communication networks.
Background
With the rise of ubiquitous communication demands and the continuous growth of high data rate data communication services, the advantages of seamless coverage and large communication capacity of satellite communication will play a key role in a new generation communication system. In addition, with the improvement of the on-board baseband data exchange and processing functions, the communication satellite can not only realize the data forwarding, but also realize the multiplexing, exchange, routing, storage and processing of the data, so that the application of the satellite communication network and the research of related technologies are endless. However, because satellite channels have the characteristics of prolonged transmission time, large delay jitter, asymmetric link bandwidth and the like, the technology which is already applied in the ground network is not fully applicable to broadband satellite communication, so that the existing ground network cannot provide a test and verification environment for application and technical research of the satellite communication network. Satellite communication networks are time-varying, massive systems that are complex complexes, rather than a large number of channels and simple tiling of satellites. Although in theory we can test and verify satellite communication network related technologies using conditional scenarios based on a real satellite communication network, a prototype system of a satellite network or an analog simulation system, there are still many limitations of these scenarios:
first, it is not practical to conduct a realistic test on an actually operating satellite communications network. Various types of satellite communication networks are burdened with important communication services and cannot be subjected to any test which may lead to network instability.
Secondly, establishing a satellite communication network physical environment capable of representing the characteristics of a large-scale and complex network, which is economically, temporally and technically infeasible; the fidelity of the satellite communication network is difficult to ensure due to small scale and simple scene. When various application tests are carried out, the satellite communication network environment also has the defects of high guarantee cost, long maintenance period, low test verification efficiency, non-visual result presentation and the like.
Thirdly, the satellite communication network is constructed by adopting the existing simulation system, and the characteristics of the satellite communication network such as channel error rate, delay jitter, time variability and the like are difficult to describe accurately, so that the simulation process and the real situation can have larger difference, and the authenticity of the simulation is difficult to ensure. The absence of a link or even the incorrect setting of a parameter will result in a poor simulation result.
