peeringinfra

Peeringinfra, short for peering infrastructure, denotes the collection of physical and logical resources that enable direct interconnection between networks for the purpose of exchanging internet traffic. It encompasses facilities, equipment, and protocols used to enable scalable, efficient, and reliable interdomain routing.

Key components include Internet Exchange Points (IXPs), route servers, peering LANs, data center colocation, and metropolitan optical networks. Equipment such as routers and switches at IXPs, traffic-handling interfaces, and control-plane systems for route advertisement (primarily BGP) form the backbone. Public peering at IXPs allows multiple networks to exchange traffic in a shared fabric, while private peering arrangements connect two networks over dedicated links. In practice, peeringinfra also relies on underlying fiber backbones and interconnect fabrics to provide sufficient capacity and low latency paths.

Operations are governed by interconnection policies, membership rules at IXPs, route filtering, and traffic accounting. Network operators choose public or private peering, set minimum traffic commitments where applicable, and use route servers to simplify many-to-many peering or configure BGP sessions to control routes, communities, and policies. Monitoring and telemetry play a crucial role in maintaining performance and detecting anomalies.

Security and reliability measures include route filtering, RPKI-based origin validation, and anti-spoofing practices to prevent route leaks and misconfigurations. Redundancy is achieved through multiple interconnection points, diverse paths, and proactive capacity planning to maintain resilience against failures.

Economics and trends: Peeringinfra reduces transit costs and can improve latency and performance. The interconnection landscape is shaped by regional needs, the growth of cloud and content networks, software-defined interconnect capabilities, and increasing emphasis on observability and security.
