o Major feature (scheduler, channel): - - Clients and relays now use new schedulers to decide which circuits - should deliver cells first. The first type is called "KIST" - ("Kernel Informed Socket Transport"), and is only available on - Linux-like systems: it uses feedback from the kernel to prevent - the kernel's TCP buffers from growing too full. The second new - scheduler type is called "KISTLite": it behaves the same as KIST, - but runs on systems without kernel support for inspecting TCP - implementation details. The old scheduler is still available, - under the name "Vanilla". To change the default scheduler - preference order, use the new "Schedulers" option. (The default - preference order is "KIST,KISTLite,Vanilla".) + - Tor now uses new schedulers to decide which circuits should + deliver cells first, in order to improve congestion at relays.

Matt Traudt implemented KIST, based on research by Rob Jansen, John Geddes, Christ Wacek, Micah Sherr, and Paul Syverson. For
