SPP provides frequently updated RTT estimates using IP traffic already
|
|
present in the network. SPP estimates the RTT between two measurement
|
|
points without requiring precise time synchronisation between each
|
|
point. SPP accurately estimates the RTT experienced by any application's
|
|
traffic without needing modifications to the application itself
|
|
or the routers along the path.
