摘要
提出一个在应用层解决应急指挥系统中异构通信网络互联问题的传输服务模型,给出模型的主要传输服务功能,对通信节点标识、转发表生成与维护以及扩充性等关键技术进行探讨。该模型结合异构通信网络的特点及发展趋势,将IP网络作为系统通信的主要方式,将其他通信方式作为实现特定通信能力的辅助手段。应用结果证明,该模型可以提升应急指挥能力,减小异构网络互通的复杂性。
This paper proposes a new model of information transmission service adapted to heterogeneous communication network of emergency command system. The main functions of the model and some key technologies such as node labeling, routing table generating & r.aintaining and so on. This model takes into account the characteristics of heterogeneous communication networks and the development trend, uses IP network as the system's main communication means, and uses other communication means to meet the special communication needs. Application proves that the model improve the capacity of emergency command system, and reduces the complexity of heterogeneous communication .
