Feeder Link
Key Points
- Connects access side to gateway or core side
- Carries aggregated traffic rather than direct user traffic
- Common in satellite and access architectures
- Handles capacity from many users or beams before reaching the core
- Operates between Edge Compute aggregation points and service backbone or gateway
Definition
Feeder Link is the link between a user-facing access element and a gateway, hub, or network core segment that transports aggregated traffic into the larger network.
Concept
Feeder Link is a system term used for the transport link between an access element and a gateway or core segment. It exists to carry aggregated traffic from the access side into the backbone or service core. It is used in satellite systems, access networks, and gateway architectures. Feeder links often handle capacity from many users or beams before it reaches the core.
Explainer
Feeder Link is the link between a user-facing access element and a gateway, hub, or network core segment that transports aggregated traffic. It works by carrying traffic from the access side into the service backbone or gateway, often after aggregation or multiplexing at the Edge Compute. It is used in satellite systems, access networks, and gateway architectures. Constraints include capacity, latency, link budget, aggregation efficiency, and the need to keep the feeder path reliable enough to support the access layer. Failure modes include feeder bottlenecks, service degradation, link loss, and capacity limitation if the feeder path cannot carry the aggregated demand. Tradeoffs involve centralized gateway efficiency versus transport complexity, aggregated capacity versus longer paths, and cost-effective scaling versus dependence on the feeder segment. Feeder Link matters because access traffic must often be moved from the Edge Compute to a core or gateway location. Cross-industry relevance is strong in satellite, broadband, and access transport systems.
