都闪开，用 UDP 才是王道
tsunami-udp
tsunami-udp 是一款专为网络加速诞生的小工具。 思路很简单，使用 TCP 进行传输控制、用 UDP 进行数据传输。
这样可以无状态的进行数据传输，然后中间加一些文件校验和重传机制，达到加速传输的目的。
传统的 tcp 传统，基于长连接，很容易受网络波动的影响。特别是网络拥塞的情况下，只能通过多进程 /线程来进行有序传输。

UDT is a reliable UDP based application level data transport protocol for distributed data intensive applications over wide area high-speed networks. UDT uses UDP to transfer bulk data with its own reliability control and congestion control mechanisms. The new protocol can transfer data at a much higher speed than TCP does. UDT is also a highly configurable framework that can accommodate various congestion control algorithms. (Presentation: PPT 450KB / Poster: PDF 435KB )
