Virtual Confine Testbed (VCT)

What is VCT

Virtual Confine Testbed (VCT) is an emulator of an actual CONFINE testbed environment. VCT is an easily deployable resource satisfying many goals simultaneously. For the end-user researcher, VCT is a platform through which he can get a quick overview of the function of a CONFINE testbed, familiarize with the environment as well as proof-test experiments destined for the CONFINE testbed. For the future CONFINE developer, VCT facilitates familiarization with CONFINE research devices (RD) and their behaviour, as an actual CONFINE OpenWrt image is used for the virtual nodes.

VCT Implementation

VCT uses two levels of virtualization as it creates virtual nodes (RDs) that contain slices belonging to experiment slivers. The actual RDs use Linux Containers (LXC) to run the slices. Thus, we need a virtualization layer that will surround the slice containers and will run the virtual node. This is achieved using KVM. Thus the two layers of virtualization are: KVM nodes and inside the slice containers, as seen in the image below.


All the scripts are softlinks to the main script The scripts are actually implemented as functions in where the main function redirects to the corresponding function after checking the name of the executable.
