Peers of AS20545

0 peers

AS20545 has no peers recorded.

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 AS20545

3 upstreams

AS174 AS20965 AS35805

AS20545 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS20545 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS20545

3 downstreams

AS29289 AS47575 AS47810

AS20545 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.
