UDT: Breaking the Data Transfer Bottleneck GB Network，网站被墙了，差不多也是高速网络大尺寸传输
There exist a number of open source projects trying to tackle accelerated file transfer via UDP. Some solutions are more mature than others and also use different technologies to solve the same problem of large data transfer over WAN.
Tsunami UDP is an open source file transfer protocol that enables high-speed data transfer over network paths with a large bandwidth delay product.
UFTP is an encrypted multicast file transfer program, designed to securely, reliably, and efficiently transfer files to multiple receivers simultaneously. This is useful for distributing large files to a large number of receivers, and is especially useful for data distribution over a satellite link (with two way communication), where the inherent delay makes any TCP based communication highly inefficient.
