AS197394 peers with these other Autonomous Systems.

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 AS197394

2 upstreams

AS197394 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS197394 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS197394

7 downstreams

AS197394 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.
