There is no thresholding for Ethernet low quality traffic.
Ethernet service route round trip delay measurements
The round trip delay is measured between two virtual switches within an Ethernet
network by means of a dedicated configurable test frame that determines the “Ethernet
service route”. To enable either a cyclic or a one-time latency measurement to a remote
NE in the TransLAN network, whereby the remote NE can be identified by inserting
its MAC address in the destination MAC address (DA) field of the test frame.
Furthermore, the traffic class, the color (dropping precedence), the VLAN identifier
and the length of the test frames can be specified, because these parameters may have
influence on the delay. The RTD measurement path follows the currently valid
STP-topology. The accuracy of the RTD measurement is 4 ms.
