多网融合的渊源在过去30多年,人类技术文明史的一个重要突破就是网络技术的融合。因为在此以前,世界上有许多种网络技术。人们很早就知道网络技术能够使人们跨越距离和时空,网络技术能够使生产力和生产效益规模性地扩展。于是,人们在特定的领域和不同的行业,根据不同的应用需求,设计出许多种不同的网络技术。例如,语音采用电路交换的电信通信网络;视频播发采用有线广播网络,而信息和数据应用采用各种不同类型的分组
The origin of multi-network integration In the past 30 years, an important breakthrough in the history of human technological civilization is the integration of network technologies. Because before that, there are many kinds of network technologies in the world. People have long known that network technology can make people across distance and space, network technology can scale productivity and productivity benefits. As a result, people in a particular field and different industries, according to different application needs, design many different network technologies. For example, voice uses a circuit-switched telecommunications network; video broadcast uses a cable broadcast network while information and data applications employ a variety of different types of packets
