电信运营商IDC 机房核心网络设计

电信运营商从基础电信业务到IDC业务提供，实现了从电信硬件产品向电信综合服务提供的转变。核心网络设计是IDC机房建设的重要组成。基于IDC机房核心系统的几大重要的建设原则，本文从Internet 接入层、核心层和服务器接入层、运营管理平台四个部分提出了核心网络架构设计的要点，并从IDC机房未来发展和客户重点需求出发，展望了防火墙技术、虚拟网络拥堵控制和节能技术等应用。通过对核心网络的良好设计，电信运营商能更好地提升企业核心竞争力，实现IDC业务的可持续健康发展。

IDC Core Network Design for Telecom Carriers

From the basic telecom service to the IDC service, the telecom carriers have realized the transformation from the telecom hardware products to the telecom integrated services. The core network design is an important component of the construction for IDC. Based on several important principles of building a core system for IDC, in this paper, the key points of the design of core network architecture are put forward, around the four parts of the Internet access layer, the core layer, the server access layer and the operation management platform. The applications of firewall technology, virtual network congestion control and energy saving technology are also prospected from the future development of IDC and the key demand of customers. Through the good design of the core network, the telecom carriers can improve the core competitiveness of the enterprise and realize the sustainable and healthy development of IDC business.
