Identifying Idle Paths in a Data Center Leaf-Spine Fabric
by Phil Gervasi
June 03, 2025
In leaf-spine data center networks, traffic often becomes imbalanced, leaving some uplinks idle and resulting in wasted bandwidth. 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.

The Scourge of Excessive AS-SETs
by Doug Madory
April 23, 2025
An AS-SET is a special object that represents a group of ASNs and forms the basis for IRR-based route filtering. 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 Hidden Cost of DIY AI in Network Operations
by Phil Gervasi
April 17, 2025
While AI offers powerful benefits for network operations, building an in-house AI solution presents major challenges, particularly around complex data engineering, staffing specialized roles, and maintaining models over time. 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.
