摘要
OTN+PTN联合组网是城域传输网实现3G及全业务统一承载的先进组网模型,目前已成为各大移动运营商建设下一代中小型城域传输网的重要解决方案。但在面对大型及超大型城域网时,原有OTN+PTN联合组网模型显现出一定的局限性,根据大型及超大型城域网的发展需求,本文分析了原有组网模型的瓶颈所在,并提出了新的联合组网思路,新思路通过RNC分区、增加核心调度设备等方式,优化模型结构,增强模型的可扩展性、可维护性及可管理性,为运营商组建大型及超大型城域传输网提供有力的参考依据。
OTN and PTN joint networking model is an advanced model to achieve the unified bearing of 3G and full-services, witch has become the major solution in building the next generation metro transport network, especially for some small and medium sized metro transport networks. However, in the face of large or super-scaled MAN（Metropolitan Area Network）, the original model reveals certain limitations. According to the development needs of MAN, a few bottlenecks of the original model are analyzed in this paper, some new ideas, such as RNC partition, the addition of core dispatching equipments are proposed to optimize the original model structure and enhance its scalability, maintainability and manageability for operators, which provides a strong reference for the formation of large and super-scaled metro transport networks.
