Local network topologies in IIoT systems include the following:
- Point-to-point: The network connects only two hosts, or devices, or network nodes, and communication only takes place between the two nodes, or devices, such as a Bluetooth link to a wireless device.
- Hub-and-spoke: An edge gateway provides a hub to connect clusters of edge nodes to each other and to the wide area network. This topology can quickly run out of capacity. Upgrading requires shutting down the hub, which in turn brings down the spoke sites.
- Meshed (peer-to-peer): This is like hub-and-spoke, but some edge nodes have routing capability and must capture or transmit data, and serve as relays for other nodes. This topology is well suited for the broad area coverage ...
