How it works

Noction IRP

Noction IRP is the BGP optimization platform for the multihomed networks. It operates at the network edge and analyses traffic to detect network congestion and blackouts. The affected network routes are probed for specific metrics such as latency and packet loss through all the available providers to reroute traffic via the best performing path. Additionally, IRP significantly reduces bandwidth bills by automatically balancing and distributing traffic flows over the less expensive provider links, while maintaining predictable traffic delivery performance. IRP adds intelligence to multihomed routing decisions. It leverages the company’s existing infrastructure to deliver substantial network performance improvements, optimizes existing Internet connectivity, and reduces the cost of operating the network. Noction IRP improves network performance by 30%-50% on average, reduces network latency by up to 50%, and increases network availability to 100%.

And no, it's not logging, metrics, or tracing. This is done via a new monitoring paradigm which makes monitoring your services easier, simpler, and cheaper. Blazing fast libraries reduce burden on existing systems and pinpoint root-cause in real-time, so the right person is alerted without playing telephone.
