本文介绍了海安广电数据网络的现状和业务需求,在此基础上提出了核心层和传输层的扁平化改造方案。特别是传输层采用双星加环形的光纤结构,能够以一张光缆网同时满足数字电视、数据以及电子政务等多种网络近期与远期的需求。 This article introduces the current situation and business requirements of MSC Data Network. On this basis, I propose the flattening and transformation scheme of core layer and transport layer. In particular, the transmission layer adopts a double star plus a ring-shaped optical fiber structure, which can simultaneously meet the short-term and long-term needs of various networks such as digital television, data and e-government with one optical cable network.
