UDT是一个可靠的基于UDP的应用层数据传输协议，主要针对广域高速网络上的数据密集型应用。UDT使用UDP传输大量的数据，具有其自身的可靠控制和拥塞控制机制。该新协议能够在非常高速度的网络上传输数据，比TCP更有优势。UDT也是一个高度可配置的框架，可适应不同的拥塞控制算法。其他也不多说了，更多内容还请关注官方链接：http://udt.sourceforge.net/

TFMCC是一个基于等式的多播拥塞控制机制，它扩展了TFRC协议，从单播到多播领域。设计TFMCC的关键挑战在于扩展的往返时间（RTT）测量、appropriate feedback suppression，以确保控制环中的反馈延迟不影响竞争流的公平性。A major contribution is the feedback mechanism, the key component of en

The eXplicit Control Protocol is a transport protocol that uses the assistance of specialized routers to accurately determine the available bandwidth along the path from the source to the destination.

當前的佇列管理演算法可以分為兩大類：被動式佇列管理（Passive Queue Management，PQM）和主動式佇列管理（Active Queue Management，AQM）。管理路由器佇列長度的傳統技術是對每個佇列設置一個最大值（以封包為單位），然後接受封包進入佇列直到佇列長達到最大值，接下來到達的封包就會被拒絕進入佇列直到佇列的長度下降。這種技術也就是所謂的"去尾"（drop-tai
