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 AS3378

1 upstreams

AS701

AS3378 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS3378 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS3378

3 downstreams

AS3371 AS3372 AS3377

AS3378 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.
