is rapid fast but it dont have paths if a line brokes
A network structure is more a star topology whereas a Hierarchical structure is like a tress... Allowing you to drill down to get to an answer.
In hierarchical topology having a single or much less nodes on top level in a very large network like data center, there exist a chance for network congestion and a small portion of available bandwidth is supported for end hosts.
hierarchical (extended) star topology
● Flat: where all the interconnection equipment have the same functions. Topology is easier to implement and has a great ease of management, provided that the network does not increase, then being recommended for small networks. ● Hierarchical: In this model the topology is divided into discrete layers, and each layer is focused on a set of specific functions, allowing the choice correct equipment for each layer. A typical hierarchical topology is composed of layers of core, composed of high-tech equipment, optimized for performance and availability, distribution, where they are concentrated equipment that control the flow of information across the network and access layer, formed by equipment that provides the connections for the network users.

tiered topology WAN
Token Ring. Nothing can communicate without the token, therefore there is never more than one device transmitting at a time, but it's very inefficient. If you want the most efficient Ethernet topology, Full Mesh would be the most efficient traffic-wise, but not cost-effective. A Hierarchical topology would be a decent compromise between cost effectiveness and efficiency.
Ring topology is the passive topology in computer networks
