What does a point-to-multipoint (P2MP) topology consist of?

A point-to-multipoint (P2MP) topology is characterized by the configuration in which a single host or central element connects to multiple receiving elements via a splitter or optical coupler. This structure allows for efficient communication where one source can transmit data to multiple destinations simultaneously.

In this type of topology, the host acts as the data source, while the splitter or optical coupler divides the signal so that it can be sent to two or more devices. This is particularly useful in scenarios like fiber-optic communications, where one optical signal needs to be distributed to multiple endpoints.

Understanding this arrangement is crucial, as it emphasizes how the distribution of data takes place in networks designed for mass communication without needing separate connections for each device, leading to cost-effectiveness and reduced complexity in wiring.
