Detailed Description

TGax VDI traffic test.

The test consider traffic values for the model presented in IEEE 802.11-14/0571r12 - 11ax Evaluation Methodology (Appendix 2 – Traffic model descriptions: Virtual Desktop Infrastructure Traffic Model) for both downlink and uplink.

The test generates traffic between two nodes and keeps track of generated TX packets (size, and timestamp). The test verifies average sizes and inter arrivals of generated packets.
