美国国防部拟定出一个庞大的计划,准备开发一个最大容量为2.4千兆比特/秒的国内通迅网络。这个网络将作为国防部长远规划中下一代国防信息系统网络的核心。工业部门的有关资料表明,此网络的造价定为1亿美元。 国防部打算用50个高速异步传输模式(ATM)开关控制这个全国范围的光缆网络(SONET)。这种高速异步传输模式开关要比美国主导遥控通讯公司——美国电话电报公司现在使用的开关先进些。 国防信息系统开发署的官员声称,他们打算利用现在由美国电话电报公司以及Sprint公司使用的、由通用服务局管理的FTS2000,政府范围的网络使Sonet迅速投入使用。一位国防信息系统开发署的官员说:
The U.S. Department of Defense has drafted a massive plan to develop a domestic communications network with a maximum capacity of 2.4 gigabits per second. This network will serve as the heart of the Defense Department’s long-planned network of next-generation Defense Information Systems. Information from the industrial sector shows that the cost of this network is set at 100 million U.S. dollars. The Department of Defense plans to use 50 high speed asynchronous transfer mode (ATM) switches to control this nationwide fiber optic cable network (SONET). This high-speed asynchronous transfer mode switch is more advanced than the switch now used by the U.S.-dominated telecoms company, AT & T. Officials at Defense Information Systems Development Agency said they intend to make use of the FTS2000, a government-wide network now managed by the ATT and Sprint, which is now being used by ATs. An official at Defense Information Systems Development Agency said:
