RFC6921>It is well known that as we approach the speed of light, time slows down. AB> I know that time slows for something when it is in speed of light, but communication is not something moving. If the packet is in speed of light we may reduce the comm-delay but never less than zero. The communication times don't change if at least one communicator is not moving in light speed. My comment is that I think this RFC is not logical, and I don't understand its recommendations. There is no way that a packet can be received before send, packet-time never changes communicators-time while the positions of both Tx and Rx are semi-fixed (change is relative to communicators' times not their signal). I think the communication-times may change when the communicators are at/above speed of light not the signal/packet. Is my physics correct?
