Point-to-point Edit. The simplest topology is a permanent link between two endpoints (the line in the illustration above). Switched point-to-point topologies are the basic model of conventional telephony. The value of a permanent point-to-point network is the value of guaranteed, or nearly so, communications between the two endpoints. Consider the topological space $(\mathbb{R}, \tau)$ where $\tau$ is the usual topology of open intervals on $\mathbb{R}$. Consider the point $0 \in \mathbb{R}$. One such local base of $0$ is the following collection: (2) Point-to-Point. Point-to-point is a network topology used for establishing one-to-one (1:1) device communications. The point-to-point topology available on Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) is optimized for audio streaming and is ideally suited for a wide range of wireless devices, such as speakers, headsets, and hands-free car kits. Point-to-Point and Star topology in Data over Fiber Applications. Fiber to the home (FTTH), now a market trend in access technology is the extreme fiber penetration concept, being widely deployed throughout the world.
