hubandspoke

Hub-and-spoke refers to a network design in which a central hub connects to multiple spoke nodes, with limited or no direct connections between spokes. In this arrangement, most traffic or activities flow through the hub, which serves as a centralized point for routing, processing, or distribution. The concept originated in transportation and logistics but has since been applied to data networks, supply chains, healthcare, and business strategy. The term is commonly written with hyphens as hub-and-spoke, while hubandspoke is a concatenated form sometimes used in writing or search queries.

Applications span several domains. In airlines, hub-and-spoke networks concentrate operations at key airports to consolidate demand, enabling more efficient scheduling and higher aircraft utilization. Large parcel carriers use regional hubs to sort and dispatch packages. In telecommunications and data networks, a central data center or router acts as the hub, directing traffic to regional nodes. In supply chains, a central distribution center may distribute goods to regional retailers. In healthcare and professional services, hubs coordinate referrals, diagnostics, or centralized expertise.

Advantages of the hub-and-spoke model include improved routing efficiency, easier capacity planning, centralized management and inventory control, and the ability to scale by adding spokes without reworking the entire network. Disadvantages center on a single point of failure at the hub, potential congestion, longer travel or transit times for spoke-to-spoke routes, and higher dependence on hub capacity and performance.

Variations exist, such as dual or multiple hubs, and hybrid models that blend hub-and-spoke with point-to-point connections. The choice depends on demand patterns, latency requirements, and risk tolerance.
