Vidyo Network Health Guidelines for VidyoDesktop

This document is to serve as guidelines only for best practice results.

Packet Loss

Packet Loss is the event where one or more packets are not received by the intended recipient as expected due to congested network or failure in transmission.
The following should be measured and presented for packet-loss:

Packet Latency

Latency is the measure of delay on the network, usually measured in milliseconds and for round trip time.

NOTE: VidyoProxy will not support latency greater than (>) 200ms>

Jitter

Jitter is a measure of the variability over time of packet latency across a network. A network with constant latency has no variation (or jitter). Packet jitter is expressed as an average of the deviation from the network mean latency.
hen jitter occurs during video/audio communication the effect is lost audio, halted audio, unnatural audio.
It is highly desirable to eliminate or minimize such events during live video/audio communications.
Monitoring the jitter provides an indication of the quality of the network.

Available Bandwidth

Available bandwidth is the amount of bandwidth available to the client.  The client statistics show the maximum available that the client may use, not the full amount available to the client host system.

For Vidyo, the uplink bandwidth is more straight-forward.  For the downlink, it is very subjective and depends on what is being viewed (the number of participants, window size, etc).

Uplink:

NOTE: Add 200Kb when data sharing  

Downlink:
