The pornosphere is a
dense layer of internet transport that is stratified in download
speed, with faster layers higher up and slower layers farther down. This is in contrast to the spamosphere near the internet's surface, which is slower higher up and faster farther down. The pornosphere is situated between about 100 kbps and 1400 kbps at
moderate connectivity. The pornosphere sits directly above the spamosphere and directly below the tunesosphere.
The vertical stratification, with faster layers above and slower layers below, makes the pornosphere dynamically
stable: there is no regular convection and associated turbulence in this part of the internet.
