信息时代,一切都在飞速发展,难怪葛鲁夫博士要用10倍速来描述这种巨变。作为信息产业的一部分,电信网络的发展更不能例外。昨天,我们还为国内电话的普及兴高采烈,那是因为电路程控交换机立下汗马功劳;而今,IP要逐渐取代电路交换成为业界热门话题。具有100多年历史的电路交换为什么会逐渐让位给分组交换?IP如何能兴起?我国的电信网络将如何发展?国家863通信高技术主题专家组副组长兼光通信专业专家组组长、中国高速信息示范网领导小组组长、信息产业部电信研究院副院长韦乐平教授在与本刊记者的访谈中,解答了其中的奥妙。
In the information age, everything is booming. No wonder Dr. Grove uses 10X to describe this change. As part of the information industry, the development of telecommunications networks is no exception. Yesterday, we also elated the popularization of domestic telephones. That was because of the tremendous efforts of circuit-controlled switchboards. Nowadays, IP has gradually replaced circuit-switching as a hot topic in the industry. How to develop IP telephony? How will the development of China’s telecom network? National 863 high-tech subject group of deputy head of the group of experts and optical communications team leader, China High Speed Professor Wei Leping, the leader of the Leading Group for Information Demonstration Network and the vice dean of the Telecommunications Research Institute of the Ministry of Information Industry, answered the mystery in his interviews with our correspondents.
