AI INFERENCE & ROUTING
The network path behind an AI response
An inference request crosses several systems before the first token appears. Knowing where it waits tells you what to fix.
Read note ↗︎02EDGE INFRASTRUCTURE
Edge inference sites: interconnection before distance
A nearby building can still have a long network path to its users. Site diligence needs to establish who you can reach, how you reach them and what happens when a connection fails.
Read note ↗︎03TRAFFIC ENGINEERING
Traffic steering is a service decision.
A route can be valid while the experience behind it is poor. Start with the service you need to deliver.
Read note ↗︎04DISTRIBUTED INFERENCE
Inference latency has more than one address.
The nearest GPU is one input to a routing decision. Queueing, model readiness and serving behavior also matter.
Read note ↗︎05NETWORK RESILIENCE
Capacity is a failure scenario.
A healthy utilization chart describes today. A useful capacity plan also describes what happens when something disappears.
