Service Providers as well as Enterprises deploying demanding, mission-critical applications, such as e-commerce, VoIP and media streaming across IP networks are facing unique networking challenges; customer demand for 100% network uptime, the potential negative economic impact from misrouting multiple gigabits of traffic, the low latency requirement and the complexity of configuration.
The Internet is a huge mesh of networks, which are interconnected by routers running BGP. Typically routers have multiple paths to the same destination. BGP calculates the best path by applying a complex algorithm. However, that algorithm doesn't take into consideration any network performance and cost metrics, often routing traffic by congested or expensive paths.
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 requires additional engineering time to be spent. Multi-homing avoids downtime by providing redundancy; however it does not address congestion-related problems that occur in the "middle-mile" backbone networks linking the Service Providers and Enterprises to end-users.
Noction IRP operates at the network edge and analyses traffic in order to detect network congestion and blackouts. The affected network routes are probed for a set of specific metrics such as latency and packet loss through all the available providers in order to reroute traffic to the best performing path.
