随着近几年来首都移动通信事业的飞速发展,北京移动通信公司原有的脱机计费模式和主机终端式营业网络已不能满足需要,因此该公司组建了新的计费及营业综合业务网络系统。 新的综合业务网是由分布在三元桥计费中心、8个交换机房、十几个营业厅的局域网以及连接它们的主用及备用广域网链路组成。整个网包括了多种型号的小型机、网络服务器和个人计算机,运行着HP-UX、WindowsNT、Windows 98等不同类型的操作系统,还包括路由器、交换器和集线器等网络设备,使用了以太网、DDN和X.25等网络协议。整个网络节点分散,结构复杂,并且对于网络传输的实时性、存储数据的完整性以及业务主机的运行状况等都有着很高的要求,如附图所示。
With the rapid development of mobile communications in the capital in recent years, Beijing Mobile’s original off-line billing model and host terminal business network can no longer meet the need. Therefore, the company has set up a new integrated billing and business network system. The new integrated services network is distributed in the Sanyuan Bridge billing center, 8 switch room, a dozen business offices of the LAN and the main and backup WAN links connecting them. The entire network includes a variety of models of minicomputers, web servers and personal computers running different types of operating systems such as HP-UX, Windows NT, Windows 98, as well as network devices such as routers, switches and hubs, using Ethernet , DDN and X.25 and other network protocols. The entire network nodes are scattered and complicated in structure, and have high requirements on the real-time performance of network transmission, the integrity of stored data, and the running status of service hosts, as shown in the accompanying drawings.
