This begs the question, which is more meaningful a metric, AS-path or hop count? Many networks have a large number of routers but the packets don’t stay in them very long. -Ben.

As for the average number of hops, it clearly depends on what type of traffic and many ASNs have more than one router. Going on my own experience I would say between 8 and 10 hops would be the average of non-cached content. If you included cached content such as cdns and caches then the actual average might be closer to 5 to 7. This is only an estimate from my own network and those of my clients so the actual value may be completely different. As with what others have said, I’m not sure on what use this data, if collected, would be. Latency is the most important. Thanks ~ Bryce Wilson, AS202313, EVIX, AS137933
