Peering is a direct, often free, traffic exchange between Autonomous Systems (ASNs). They share routes only to their own networks and customers, making connections faster and cheaper for that specific traffic, without providing full internet access to each other.

Upstreams of AS56307

4 upstreams

AS4826 AS13335 AS17732 AS38195

AS56307 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS56307 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS56307

1 downstreams

AS17918

AS56307 provides internet connectivity to these downstream Autonomous Systems.

A downstream is a customer Autonomous System that pays another AS (its provider) for internet access. The provider AS carries the downstream's traffic and makes its network reachable.
