构架中国的“数码大厦”

Erecting the Chinese “Digital Building”

因特网数据中心（ＩＤＣ） 已成为承载各种模式电子商务的基本设施。作为新的服务模式，ＩＤＣ重新创造了因特网服务的价值链，形成了不同分工的因特网服务提供商。高速、安全是ＩＤＣ提供高质服务的两个方面。ＩＤＣ改变了传统客户／服务器的服务模式，将ＩＣＰ的访问服务器从边缘移到了高速核心骨干网中心交换点，从而减少了不必要的承载负担，提高了有效速度。而多节点数据中心通过容灾备份保证了数据安全，是未来的发展趋势。

Internet data center(IDC) has become the infrastructure for bearing various modes of e - business services. As a new serve mode, IDC has recreated the value chain of Internet services and formed various ISPs. High speed and security are two key points of the IDC for providing high quality services. IDC has changed the conventional client! server service mode by moving the access servers of ICP from the network edge to the central switching point of the high speed core backbone network, reducing unnecessary burdens and increasing the effective speed. The multinode data center ensures data security by capacity duplication, which is the forth-coming development trend.
