大规模突发激光宽带通信中,信道拥堵和干扰影响了信道通信机能。在这种现状下,设计大规模突发激光宽带通信网络数据信道调度平台,采取平台硬件控制通信拥堵,利用调度方法解决吞吐量超限。通过分析激光带宽通信的大规模突发原理,设计以SW-2000D调度机为核心的调度平台,分模块介绍了平台硬件。使用网络数据拓扑结构对平台进行模型化,将大规模突发激光带宽通信时间分段,提出调度方向模型、队列模型以及可靠通信模型。以三个模型的限制条件为基础,设计分布式调度方法。仿真实验结果证明,所设计的平台能够大面积减少信道拥堵率,并且信道抗干扰机能强。
In large-scale burst laser broadband communication, channel congestion and interference affect the channel communication function. In this situation, the design of large-scale burst laser broadband data communication network data channel scheduling platform to take platform hardware control communication congestion, the use of scheduling methods to solve the throughput limit. By analyzing the large-scale burst principle of laser bandwidth communication, a scheduling platform with SW-2000D dispatching machine as the core is designed, and the platform hardware is introduced in modules. The network data topology is used to model the platform. The large-scale burst laser bandwidth communication time is segmented, and a scheduling direction model, a queue model and a reliable communication model are proposed. Based on the constraints of the three models, a distributed scheduling method is designed. Simulation results show that the designed platform can reduce the channel congestion rate in a large area and the channel anti-interference function is strong.
