Traffic shaping for camouflage
How burst scheduling, half-duplex shaping, and target-traffic mimicry try to make tunnels look like something else.
The Track 4 padding module covered defenses that obscure the shape of encrypted traffic from passive observers. Track 6 returns to the same problem from the circumvention angle: how do circumvention transports actively shape their traffic to mimic benign traffic, defeating both passive classification and active probing? The shift in framing matters: padding hides what you're doing; camouflage tries to make you look like you're doing something else.
This module covers the design space: burst-scheduled transmission, half-duplex shaping, target-traffic mimicry (Walkie-Talkie's matched-page-load approach), and the operational realities of making one application's traffic look like another's. The thesis: shaping helps but doesn't solve the problem; behavioral and contextual mismatches survive even careful shape mimicry.
