Hubipõhine

Hubipõhine, also known as hub-based or hub-and-spoke, is a network topology in which a central hub is connected to multiple nodes or spokes. This topology is commonly used in both computer networks and transportation systems. In computer networking, the hub acts as a central point where all data packets are sent and received. Each node is connected to the hub, and data is transmitted to the hub, which then broadcasts the data to all connected nodes. This can lead to inefficiencies, as all nodes receive every packet, regardless of its intended recipient. However, hub-based networks are simple to set up and manage, making them suitable for small networks or temporary setups.

In transportation, the hub-and-spoke model is used to describe a system where a central hub serves as a connecting point for multiple spokes or branches. This model is often used in airline networks, where a central airport (hub) connects to multiple smaller airports (spokes). Passengers can travel from a spoke to another spoke via the hub, which can be more cost-effective and efficient than direct flights between all pairs of spokes. This model allows for economies of scale and can reduce overall costs and improve service reliability.

Despite its simplicity and cost-effectiveness, the hub-based topology has limitations. In computer networks, the central hub can become a bottleneck, especially as the number of connected nodes increases. Additionally, the broadcast nature of hubs can lead to increased network congestion and reduced performance. In transportation, the hub-and-spoke model can lead to longer travel times for passengers who must travel via the hub, even if a direct connection exists between their origin and destination. Despite these limitations, the hub-based model remains a popular choice due to its simplicity and efficiency in certain contexts.
