Jattack: A WebRTC load testing tool

We present Jattack, an automated stressing tool for the analysis of the performance of WebRTC-enabled server-side components. Jattack has been initially conceived with the primary objective of performing a thorough scalability analysis of the well-known Janus WebRTC gateway. As such, it re-uses most of the Janus core stack components in order to reliably emulate the behavior of a dynamically adjustable number of WebRTC clients. The specific testing .scenario can indeed be programmatically reproduced by writing a small "controller" component, which takes on the responsibility of properly orchestrating the scenario itself. The general-purpose nature of the tool, together with its flexibility deriving from the controller-based programmable approach, makes Jattack also suitable for stress-testing other WebRTC-enabled servers.
