城域承载网网格化规划场景模型及部署策略研究

Research on the Scene Model and Deployment Strategy of Metropolitan Area Network Planning

目前运营商城域承载网普遍存在县市业务接入控制节点过多,设备利用率低的情况,随着大容量设备的引入,部分节点利用率将在20%以下,这与未来承载网"大容量、少节点、扁平化"的总体架构存在差距。因此,有必要提前做好业务接入控制节点规划,通过业务接入控制层节点的适当收敛,提高设备资源利用率,减少设备数量,提高网络整体综合投资效益。

The mall operators domain bearing network widespread counties service access control too many nodes, equipment utilization rate is low, with the introduction of large capacity equipment, part of the node utilization rate will below 20%, this and future carrying network ＂high capacity, less nodes, flat＂ framework and structure of the gap. Therefore, it is necessary to do in advance to service access control node planning, through service access control appropriate convergence layer nodes, improve equipment utilization rate of resources, reduce the number of equipment, improve the overall network comprehensive investment benefit.
