城域传送网骨干层未来发展趋势

Future Development Trends of Backbone Layer on Metrpolitan Area Network

基于对现有移动传送网现状的分析,对于专线、话音等小颗粒业务,目前的SDH/MSTP网络已经提供了完善的解决方案。但面对爆炸式增长的大颗粒带宽业务,现有的网络和技术则无法很好的解决。城域网必须具备大容量、高带宽、多业务、高可靠性等能力,从而实现骨干层层面的宽带IP化业务支持能力。

Based on the analysis of existing mobile transmission networks, current SDH/MSTP network has provided a complete solution on voice and other small particle services. But facing explosive growth of large granular bandwidth services, the existing network and technology have not good solutions. MAN must possess large capacity, high-bandwidth, multi-service and high reliability to achieve broadband IP service suppont capabilites on backbone layer.
