Detailed Description

A simple Virtual Desktop Infrastructure (VDI) traffic generator example over Wi-Fi.

This example demonstrates how to set up a basic ns-3 simulation with VDI traffic over a Wi-Fi network. VDI traffic models remote desktop applications where a server sends desktop display data to clients.

The simulation consists of:

A simple Wi-Fi network with one AP (Access Point) and one STA (Station)
VDI traffic flowing from the AP (server) to the STA (client) for downlink
Optional uplink traffic from STA to AP for navigation/feedback
Application-level tracing to observe VDI packets being sent

The VDI traffic model follows IEEE 802.11-14/0571r12 TGAX evaluation methodology:

Packet inter-arrival times follow an exponential distribution
Packet sizes follow a normal distribution (bimodal for downlink)
Initial packet arrival is uniformly distributed in [0, 20ms]

Traffic direction parameters from the specification:

Downlink (AP to STA): Mean arrival 60.2269ms, bimodal packet size (41/1478 bytes)
Uplink (STA to AP): Mean arrival 48.2870ms, normal packet size (mean 50.598 bytes)

To run downlink traffic (default): ./ns3 run tgax-virtual-desktop-example To run uplink traffic: ./ns3 run "tgax-virtual-desktop-example --direction=uplink" To run bidirectional: ./ns3 run "tgax-virtual-desktop-example --direction=bidirectional"

To disable verbose logging: ./ns3 run "tgax-virtual-desktop-example --verbose=false"
