Mustufa Sir
1. CLASSIFICATION OF QOE/QOS
MAPPING MODELS
QoE/QoS mapping models can be classified
according to their inputs into three categories:
1. Black-box media-based models
2. Glass-box parameter-based models
3. Gray-box parameter-based models
Mustufa Sir
1. Black-Box Media-Based QoS/QoE Mapping
Models
Mustufa Sir
2. Glass-Box Parameter-Based QoS/QoE
Mapping Models
• A well-known offline glass-box parameter-
based model, named E-Model, has been
defined by the ITU-T.
• E-Model aims at estimating QoE of voice calls
transmitted over a planned transport
infrastructure
Mustufa Sir
3. Gray-Box QoS/QoE Mapping Models
Mustufa Sir
2. IP-ORIENTED PARAMETER-BASED
QOS/QOE MAPPING MODELS
• Network Layer QoE/QoS Mapping Models for
Video Services
where AL and VL refer respectively to audio and video packet loss rates, AJ
and VJ represent respectively audio and video packet jitter (VJ), and RSSI is
the received signal strength indicator.
Mustufa Sir
Mustufa Sir
• Application Layer QoE/QoS Mapping Models
for Video Services
where Lx refers to the start-up latency, that is, the waiting time before playing a video
sequence, N is the number of quality switches that count the number of times the
video bit rate is changed during a session, N is the number of rebuffering events, and T
is the mean rebuffering time.
Mustufa Sir
3. ACTIONABLE QOE OVER IP-BASED
