面向业务集中化发展的专用IP承载网网络架构演进分析

随着云资源池的大规模建设,业务系统集中化部署成为发展趋势,跨省流量的激增对专用IP承载网骨干网带来挑战。本文分析了现有和未来的业务流量占比变化以及新型业务的特点,创造性地提出了构建骨干网新平面的网络架构演进思路。新平面可根据业务需求调整网络设计指标和保护策略,并优先引入SDN技术。演进架构可以为不同类型的业务提供差异化服务,同时最大限度地降低网络建设成本并推进专用IP承载网全面引入SDN技术的进程。

Analysis of the dedicated IP network architecture evolution facing the centralized business development

With the large-scale construction of cloud resource pool, centralized business system deployment becomes the trend of development. The dramatic increasing of inter-provincial flow brings challenges to the backbone of the dedicated IP network. This paper analyses the changing proportion of different business flow in current and future operation, and it illustrates characteristics of new businesses as well. Then, a network architecture evolution idea of constructing a new backbone plane is proposed creatively. The new plane could adjust the network design index and protection strategy according to business requirement, and it could also prior introduce SDN technology. As a result, the evolved architecture could provide different types of business with appropriate services, minimize the network construction costs, and promote the process of fully introducing SDN technology in dedicated IP network.
