Airhook is a reliable data delivery protocol, like TCP. Unlike TCP, Airhook gracefully handles intermittent, unreliable, or delayed networks. Other features include session recovery, queue control, and delivery status notification.
UDT is an application level data transport protocol for the emerging distributed data intensive applications over wide area high-speed networks (e.g., 1 Gb/s or above). UDT uses UDP to transfer bulk data and it has its own reliability control and congestion control mechanism. This new protocol is not only for private or QoS-enabled links, but also for shared networks. Furthermore, UDT is also a composable framework that can accommodate various congestion control algorithms.
