QoS Considerations for CAD software
The most important network traffic for quality of service consideration in the CAD software is the voice
streams sent between VoIP requestors and providers. The processes that send and receive these voice
streams have been set to have higher priorities than other processing threads. This helps assure that there
will be no delays in processing these voice streams. However, The voice streams themselves contain no
QoS markings. These markings are stripped off when the voice streams are captured by the VoIP
provider's software. The networking components used to send these data streams (switches, routers,
gateways) should be configured with the appropriate QoS settings to ensure the delivery of these voice
streams to meet the intended QoS requirements.
