Kentik helps engineers identify underutilized paths, diagnose the causes, and take corrective action using enriched telemetry, visual topology maps, and intelligent alerts, turning hidden inefficiencies into actionable insights.

However, many AS-SETs in circulation today have grown so big that they effectively whitelist much of the routing table, rendering them ineffective. According to recent analysis, there are currently 2,192 AS-SETs which expand to over 1,000 ASNs each! In this blog post, we’ll describe what an AS-SET is, its role in route filtering, and how to deal with excessively large AS-SETs.

The effort required to handle real-time telemetry, retrain models, and manage evolving environments is often too great for most IT teams. For enterprise networks, partnering with a vendor that specializes in AI and network operations is typically a more efficient, scalable, and sustainable approach.
