A partially interconnected network has a plurality of topological nodes, each of the topological nodes having at least three direct point-to-point topological links connected to other topological nodes. Each of a proportion of the plurality of topological nodes is connected to one of a group of point-of-presence (PoP) units. The group of PoP units is arranged to provide access to a selected service or services, one or more of each of the at least three direct point-to-point topological links from each topological node not being connected to one of a group of PoP units connecting to one or more than one of the plurality of topological nodes being connected to one of the group of PoP units. There is at least one choice of routing between any two topological nodes, the choice of routing being either via two topological links connected in series at another topological node or a direct point-to-point topological link between the two topological nodes.
(ZH) 一种部分互连网络具有多个拓扑节点，每一个拓扑节点有至少三条连接到其它拓扑节点的直接点对点拓扑链路，所述多个拓扑节点的一部分中的每一个连接到一组入网点(PoP)装置中的一个。所述一组入网点装置配置成提供对一种选择的服务或多种选择的服务的访问，每一个拓扑节点的所述至少每三条直接点对点拓扑链路中的一条或一条以上不连接到与所述多个拓扑节点中的一个或一个以上连接的一组入网点装置中的一个，所述多个拓扑节点中的一个或一个以上连接到所述一组入网点装置中的一个。在任意两个拓扑节点之间存在至少一种路由选择，路由选择或者是通过在另一个拓扑节点处串联连接的两条拓扑链路或者是在两个拓扑节点之间的直接点对点的拓扑链路。
