综合业务交换网系统就是由多台交换机组成的基于IP交换的传输网络。其系统主用由3部分组成:核心层交换机、汇聚层交换机和接入层交换机。通信部门可以通过此综合交换网系统方便的为管制、气象、导航、及机场等用户提供所需的多种通信业务,也能通过此系统的预留端口随时为用户增加所需的新业务,而不必采用每增加一项业务就增加一套传输线路的传统模式,此系统的应用不但能加强通信传输的安全、提高通信维护工作效率,还能够大大降低整网传输的成本。
Integrated service switching network system is composed of multiple switches based on IP exchange transmission network. The main system consists of three parts: the core switches, aggregation switches and access layer switches. Through this integrated switching network system, the communications department can conveniently provide users with many kinds of communication services required for control, meteorology, navigation and airport users, etc., and can also add necessary new services to users through the reserved ports of the system at any time, Instead of using the traditional mode of adding one transmission line for each additional service. The application of the system can not only enhance the security of communication transmission, improve the efficiency of communication maintenance work, but also greatly reduce the transmission cost of the entire network.
