What is Hub & Spoke?

Also known as: One to Many

Ethernet Hub and Spoke is a ‘one to many’ architecture that offers a cost-effective solution to connect multiple services/locations (spokes) to a central site through a single, aggregated interface. Carrier ethernet services reduce complexity and are space efficient at the Hub site. A point-to-point network connects directly to a set of locations without interrupting services (e.g. pick up or drop off), even if the route may not be direct. A (pure) hub-and-spoke network connects every location through a single intermediary location called a hub. As a network structure, hub-and-spoke allows greater flexibility within the transport system through a concentration of flows.

The Hub location can support bandwidths of 1GB or 10GB while Spoke location bandwidth speeds can range from 2MB to 1GB. The individual spoke circuits are separated using VLANs.


We know businesses need to adopt a coherent and holistic strategy across their technology infrastructure. Colt’s Cybersecurity Programme, including Encryption, is designed to address the growing need for effective network security solutions, driven by increasing threats and new regulatory requirements.
