8.10 QoS/Classification Setting


Classify Setting Tab
iPASOLINK supports QoS based on MEF10 and REC4115, which classifies the
traffic into eight or four classes with the proper Internal Priority according to the
predetermined profile. Except for the default profile, a user can configure up to
three additional profiles, which provides a capability of realizing the flexible and
user-orientated QoS strategy. The Internal Priority is used for the following
purposes:
ii) Maps the eight classes of ingress traffic to four or eight classes at queuing the
iii) Copies the original internal priority to the encapsulated frame to prevent the
Three modes are available for QoS Classification.
1. Equipment Based QoS Mode (default)
QoS classification policies are determined by per-equipment basis. One
classification profile is activated, and up to three profiles are stored on the
equipment configuration. In this mode, most outer QoS field of the packet can be
specified for the classification policy.
2. Port Based QoS Mode
QoS classification policies are determined by per-port basis. In this mode, inner
QoS field of the packet can be specified for the classification policy.
3. VLAN ID Based QoS Mode
QoS classification policies are determined by per-VLAN ID basis. In this mode,
VLAN ID field of the packet can be specified for the classification policy.

Policer Setting Tab
At the ingress traffic, the internal priority is assigned to the frame to perform the
flow control according to the predetermined policer and the Yellow or Green
Marker that is applied to the frame to define whether to discard or forward the
frame.

Shaper Setting Tab
At the egress traffic, frames are queued according to the internal priority where the
Yellow or Green Marker is applied to determine whether to discard or forward the
frame.
