IAT Before and After Router

Packet-loss that occurs before or inside a router will usually not be visible since the queuing mechanism at
the outgoing interface of the router will send out packets in an orderly fashion. If however the packet-loss
did occur after the router (due to line noise for example) thus affect the timing between two neighboring
packets – effectively doubling it – the packet loss will always affect the IAT component for CBR streams.
For VBR streams, that are jittery by default, the extra time gap may have no effect since there may
already be other larger gaps within the MediaWindow interval.

If a UDP packet goes missing after it has left the router it will visually affect both the IAT and MLR for
CBR streams. The pink line represents one elementary measurement.
