Project Overview

The VRDPI is intended to be a tool for deep packet capture and analysis in Virtual Reality. Using standard virtual reality controls (Oculus Touch, Vive Motion Controllers) users will be able to select a network interface to capture and a duration of the capture. Packet capture will be completed in the background (seperate thread) and the results will be displayed inside VR.

Project Goals

• Render deep packet inspection results in a virtual reality environment. Utilizing the WinPCap library, Unreal Engine 4 with 99% C++ UE4 API.
• Renders each TCP/UDP session in the form of a packet column. The packet columns representing each session’s packet stream are arrayed in front of the user after capture in the form of a semi-arc.
• Users will utilize standard VR motion controller interface patterns to navigate the VR environment. Including VR teleportation, direct controller to object manipulations, and controller to remote object at a distance manipulations.
• User can also resize a packet to make the data displayed on its front face larger and more clear.
• Information inside the packet is divided into layers which represent each layer of the network stack. Frame layer, Ethernet layer, IP layer, TCP layer, and finally the application layer.
• Each layer will be color coded. Each layer will display its data in hexadecimal format.

First Screenshot of VRDPI

• Created VRDPI Unreal Engine 4.15.1 Project using the C++ template.
• Imported relevant class files from DemoA project.
• Created large (5km x 5km) floor.
• Created "Target" material in Photoshop (2000x2000) for origin floor indicator. Imported into UE4 as texture.
• Created blender model for podium. Imported into UE4 as static mesh.

First Packet Capture of VRDPI

3/24/17

• Created PacketHelper class and linked the WinPCap static library into the project.
• Extended PacketHelper as a child of FRunnable UE4 class in order to make the packet capture multithreaded.
• Successfully tested packet capture in VR.

3/25/17

• Researched how to properly integrate C style callbacks with UE4.
• Reconfigured PacketHelper class to push data back to PlayerController object.

3/26/17

• Created PacketHolder class to contain individual packets.
• Added static methods for retrieving adapter configuration to PacketHelper.
• Created Podium class and podium widget dialog to let the user setup and initiate the packet capture.

• Debugged and improved the Podium widget
• Created AdapterButton class to contain the buttons which display the adapter list on the podium.
