PeeringPunkte

PeeringPunkte refer to interconnection points in the internet where networks exchange traffic. They are physical or virtual locations that enable direct interconnection between networks, allowing efficient routing and local traffic exchange.

Public peering at shared facilities, often called Internet exchange points (IXPs), uses route servers and switching infrastructure to connect many participants. Private peering is a direct, bilateral link between two networks, typically used for higher traffic volumes or specialized arrangements. Networks establish BGP sessions at these points and implement exchange policies to control which routes are advertised and accepted.

PeeringPunkte are usually operated by IXP organizations, telecommunications carriers, or data center operators. Access policies are defined by membership agreements, with participants selecting port speeds, switching fabric, and whether to use public or private peering. Some facilities offer additional services such as route servers, traffic engineering tools, and DDoS protection.

The main benefits include reduced transit costs, lower latency, greater control over routing, and improved resilience through alternative paths. Challenges may include capacity planning for growing traffic, meeting peering criteria, ensuring security and route hygiene, and dealing with multi-party governance.

Globally, peeringPunkte are concentrated in major metropolitan areas with large networks and data volumes; smaller regions rely on regional IXPs or private interconnects. The concept underpins the efficiency and redundancy of modern internet infrastructure.
