Tree network topology A tree topology , or star-bus topology , is a hybrid network topology in which star networks are interconnected via bus networks . [ 1 ] [ 2 ] Tree networks are hierarchical, and each node can have an arbitrary number of child nodes.
Star topology in use in a network. A star network is an implementation of a spoke–hub distribution paradigm in computer networks. In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. [1] The star network is one of the most common computer network topologies.
Hybrid networks combine two or more topologies in such a way that the resulting network does not exhibit one of the standard topologies (e.g., bus, star, ring, etc.). For example, a tree network (or star-bus network) is a hybrid topology in which star networks are interconnected via bus networks.

Topology of a bus network. A bus network is a network topology in which nodes are directly connected to a common half-duplex link called a bus. [1][2] A host on a bus network is called a station. In a bus network, every station will receive all network traffic, and the traffic generated by each station has equal transmission priority. [3]
A star-wired bus was much easier to build and expand (and was more readily maintainable) than the clumsy linear bus Ethernet of the time. The "interconnected stars" cabling topology made it easy to add and remove nodes without taking down the whole network, and much easier to diagnose and isolate failures within a complex LAN.
A conceptual diagram of a local area network using bus network topology. A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. [1] By contrast, a wide area network (WAN) not only covers a larger geographic distance, but ...
For a network of n nodes, only n − 1 routes are necessary to connect all nodes so the upper bound is n − 1, and the complexity is O(n). That compares favourably to the () routes, or O(n 2), which would be required to connect each node to every other node in a point-to-point network. For example, in a system with 6 destinations, the spoke ...
