Does differentiating traffic into multiple timing classes make traffic timing analysis easier? (For example, while high-latency traffic is better protected from fingerprinting, low-latency traffic is easier to identify and fingerprint.) > We plan to integrate the mix into Tor version 0.2.5.10 and analyze its > performance along with the Shadow simulator.
