Mosh accomplishes this feat by using the UDP-based state-synchronisation protocol ( SSP), which isn't bound to a particular network connection.
If you have a low-bandwidth or intermittent connection, switch between multiple devices or ISPs or even use devices with sporadic Internet access you will be able to maintain consistent shell sessions with Mosh. Mosh, a portmanteau word for mobile shell, is a terminal connection program that facilitates persistent shell sessions in less-than-ideal network situations.
