最近两年,电信业务的收入飞速增长,据预测,电信的收入将由1997年的1950亿美元增加到2000年的2600亿美元。与此同时,传统电信业的支柱—电话的收入已经开始逐年下降。电信收入的主要增长点来源于以IP为主的数据业务,预计到2000年,数据业务将占整个电信收入的80％,IP协议也逐步成为数据通信中的主导协认。许多原来的传统电信业务向IP转移。那么,IP骨干网中的传输技术发展如何?
In the last two years, revenue from telecom services has been growing rapidly. It is estimated that the revenue of telecommunications will increase from 195 billion U.S. dollars in 1997 to 260 billion U.S. dollars in 2000. At the same time, revenue from the phone, the backbone of the traditional telecom industry, has begun to decline year by year. The main growth point of telecom revenue comes from IP-based data services. It is estimated that data services will account for 80% of the total telecom revenue by the year 2000, and the IP protocol has also gradually become the dominant agreement in data communications. Many of the original traditional telecom services to the IP transfer. So, IP backbone network transmission technology development?
