[dev] RTT

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
