15. Verdades no documentadas de QoS
• QoS funciona de punto a punto
• En WAN, funciona igual QoS
• Packets Inspector
• Traffic Accelerator
• En LAN funciona al 100% QoS
• SBC
• Devices, Deskphone

16. Verdades no documentadas de QoS
• Es mejor poner express route

17. Conclusiones de QoS
• Poner QoS nos dará mejoras, no
importa lo pequeñas que puedan
ser
• Saber que no será el 100% de
nuestros streams los que tengan
QoS
• Definir bien los alcances y
métodos que funcionan en mi
ambiente.

20. Clasificacion en CQD
Metric Condition Explanation
Audio Degradation
Avg
> 1.0 Average Network
Mean Opinion
Score degradation
for stream.
Represents how
much the network
loss and jitter has
impacted the
quality of received
audio.
Round Trip > 500 Average network
propagation round-
trip time computed
as specified in
RFC3550 in
milliseconds.
Packet Loss Rate > 0.1 Average packet loss
rate for stream.
Jitter > 30 Average jitter for
stream in
milliseconds.
Ratio Concealed
Samples Avg
> 0.07 Average ratio of the
number of audio
frames with
concealed samples
generated by
packet loss healing
to the total number
of audio frames.
Step # Metric Condition

> 50% Poor Good Proceed to step 2 Average
percentage of
video frames lost
as displayed to
the user. This
includes frames
recovered from
network losses.

Avg
< 7 Poor Good Proceed to step 3 Average frames
per second
received for a
video stream,
computed over
the duration of
the session.

across all video
streams and

Metric Condition Explanation
Spoiled Tile
Percent Total
> 36 Percentage of
tiles that are
discarded instead
of being sent to a
remote peer (for
example, from the
MCU to a viewer).
Discarded (or
spoiled) tiles may
be caused by
bandwidth
restrictions
between client
and server.

the RDP Stack at
the conferencing

one-way delay
between the
endpoints in
seconds for
application
sharing streams.
