Yee: Maybe specify:
- Propagation Delay (T_pT~p~): The time it takes for a packet to transfer across the network path when the queuing and transmission delays are zero.
- Transmission Delay (T_dT~d~): The time it takes for a packet to be processed and transfered through the network nodes.
- Queuing Delay (T_qT~q~): Variation in the end-to-end delay because the packet had to be serviced by deviced due to queuing.
...
As such, the one way latency along a network path is composed of
T = T_p + T_d + T_qT~p~ + T~d~ + T~q~
Bearing in mind that the transmission and queuing delays may be at both ends of the peer link, for a single hop, we have
T_i = T_p + (T_d)_i + (T_d)_T~i = T~p + T~d~i + T~d~i+1 + (T_q)_T~q~i + (T_q)_T~q~i+1
And the complete end-to-end one way latency is defined as
T = Sum_n of T_iSum^n^i of T~i~
where n is the total number of nodes along a route.
