[dev] RTT

[Sofia Salgueiro]

Good afternoon,

I've been using CORE with FRRouting and I've noticed that the PING rtt between two directly connected router devices is approximately 80 us, even if I change the bandwidth of the links. I've also noticed that this value seems to increase with the number of hops, eg. between 2 routers with 4 links the value doubles to approximately 160 us.

So, I was wondering if maybe you could give me some insight on how the PING is emulated and, more specifically, why the rtt has this value?

Best regards,
Sofia Salgueiro
