Title: Mosh: A State-of-the-Art Good Old-Fashioned Mobile Shell

Abstract: Mosh (mobile shell) is a remote terminal application that
supports intermittent connectivity, allows roaming, and speculatively
and safely echoes user keystrokes for better interactive response over
high-latency paths. Mosh is built on the State Synchronization
Protocol (SSP), a new UDP-based protocol that securely synchronizes
client and server state, even across changes of the client’s IP
address. Mosh uses SSP to synchronize a character-cell terminal
emulator, maintaining terminal state at both client and server to
predictively echo keystrokes. Our evaluation analyzed keystroke traces
from six different users covering a period of 40 hours of real-world
usage. Mosh was able to immediately display the effects of 70% of the
user keystrokes. Over a commercial EV-DO (3G) network, median
keystroke response latency with Mosh was less than 5 ms, compared with
503 ms for SSH. Mosh is free software, available for GNU/Linux, Mac OS
X, BSD, Android, Cygwin, and most other flavors of Unix.
