BGP routing efficiency is one of the greatest challenges for multi-homed networks. Despite increased demand for a consistent, reliable network to support business-critical applications, traffic performance across the Internet remains unpredictable, suffering from frequent congestion and network failures. Network administrators are trying to deal with these problems by adding additional providers, reactively creating and applying routing policies, and rerouting the traffic manually.
This paper explains why manual BGP tuning is not enough for efficient traffic routing across multiple transit providers and why automating route optimization is a step up in maximizing network uptime and ensuring best connectivity to customers.

Noction IRP is designed to improve the performance and reduce the costs of running a multi-homed BGP network. The platform operates at the network edge and does non-intrusive traffic analysis in order to detect network con-gestation and blackouts. The affected network routes are probed for a set of specific metrics through all the available providers in order to reroute traffic to the best performing path.
