HYBRID NETWORK STRUCTURE

                                     hybrid network

A hybrid network is constructed of different topologies, such as ring, star and bus.

Wide Area network: Wide area networks (WHNs) are commonly hybrid networks. WANs often connect multiple network structures to create one large network. For example, a company could use the star network structure in one office and the the bus network structure in another office. The individual networks could then be connected by a microwave or satellite to from a hybrid network.
Setup: A hybrid network usually created when a network is expanded to accommodate an increase in traffic. Hybrid network can use variety of device, such as hubs, routers  bridges, to join  different network  structures. It is quite difficult  to set up a  hybrid  network   because  the devices have to be configured  to allow  the different networks structures to work together. 
Troubleshooting: As a hybrid network uses  several technologies, it can be difficult to manage and troubleshoot. When an error occurs on a hybrid network, the source of the problem  can be difficult to find. A company using a large hybrid network usually has its own network support department.
