A hub and spoke network topology is a type of network architecture where all devices (spokes) in the network are connected to a central device called a hub. The hub acts as a central point of connection, routing data between the spokes.
In a hub and spoke network, the spokes typically do not have direct connections with each other. Instead, they communicate with other devices by sending data to the hub, which then forwards the information to the appropriate destination. This centralization of network traffic allows for easier management, monitoring, and control of the network.
Some key characteristics of a hub and spoke network topology include:
- Centralization: The hub serves as a central point for network administration and resource allocation. It controls the flow of data between the spokes.
- Scalability: The hub and spoke model is scalable as new devices can be easily added or removed by connecting them to the central hub.
- Dependency: The spokes are dependent on the hub for communication. If the hub fails, the entire network may be affected.
- Network traffic: All data between spokes must pass through the hub, which can lead to increased latency and potential bottlenecks if the hub becomes overloaded.
Following image shows how to use this topology to control access to various development environments as an example:
In this case, both negative characteristics are acceptable because only the production environment is business critical.
