      子架保护存在单节点失效业务全部中断风险。双子框双方向业务分担,有效防范单节点失效风险。骨干环路双子框分环路分担,核心环路双子框分方向分担。
      调度能力环内和环间可进行任意调度,光支路板可上波到任一光方向。环内和环间可进行任意调度,光支路板可上波到任一光方向。跨子框穿通波道需要通过双子架互联的光线路板调度,穿通业务需要做好波长规划,避免波长冲突。
      可扩展性基本满足现有环路业务落地扩容需求。江北区域槽位受限不满足业务落地扩容需求;江南区域基本满足现有环路业务落地扩容需求。槽位充足满足现有环路业务落地扩容需求。支持网络向扁平化、一体化和全光调度网络架构演进。
      上下波后续需叠加扩展框实现更多波长上下。后续需叠加扩展框实现更多波长上下。双子架槽位更充足,根据业务需求可叠加扩展框实现更多波长上下。

      互联通道的业务调度需求1、核心环路的穿通波道业务。2、在核心站点落地的同源同宿业务,其中一条业务需要占用互联通道。1、跨域的穿通波道业务。2、在核心站点落地的同源同宿业务,其中一条业务需要占用互联通道。1、核心环路的穿通波道业务。2、跨域的穿通波道业务。3、在核心站点落地的同源同宿业务,其中一条业务需要占用互联通道。1、跨域的穿通波道业务。2、在核心站点落地的同源同宿业务,其中一条业务需要占用互联通道。
      业务落地单板1、业务落地单板严格分到两个方向的子框,东西向业务板卡分离。2、下挂的全部骨干环路单边业务集中配置在同一个设备子框。1、环路的业务分担到两个设备子框内。2、单环业务配置在同一子框。1、骨干环路业务在两个子框分担。2、核心环路业务东西向业务分子框。1、骨干环路业务在两个子框分担。2、在核心站点落地的同源同宿业务可以配置到两个子框。3、核心环路东西向业务分子框。
