Netty 构建HTTP服务器示例: http://donald-draper.iteye.com/blog/2383527
前面的文章我们看了Netty tcp,http协议通信实例,大部分项目用Netty一般用TCP协议,很少用UDP协议,官方文档中,UDP协议的实例都很少,我们在实例可以看到一个UDT的实例包,UDT协议是基于UDP的数据传输协议(UDP-based Data Transfer Protocol,简称UDT),是一种互联网数据传输协议。UDT的主要目的是支持高速广域网上的海量数据传输,而互联网上的标准数据传输协议TCP在高带宽长距离网络上性能很差。 顾名思义,UDT建于UDP之上,并引入新的拥塞控制和数据可靠性控制机制。UDT是面向连接的双向的应用层协议。它同时支持可靠的数据流传输和部分可靠的数据报传输。 由于UDT完全在UDP上实现,它也可以应用在除了高速数据传输之外的其它应用领域,例如点到点技术(P2P),防火墙穿透,多媒体数据传输等等。
关于UDT协议,可以参见以下这个一些的文章:
UDT协议-基于UDP的可靠数据传输协议的实现分析(1)-准备工作: http://jimmee.iteye.com/blog/2037451,以后再认真研究一下UDT协议。
在netty实例中,UDT实例有UDT Byte Stream(TCP-like byte streaming mode) ,UDT Message Flow(UDP-like message delivery mode)及相关的对等Peer通信,测试结果UDT Message Flow类型的实例存在bug, see #https://github.com/netty/netty/issues/6934. Netty官方显示UDT将被丢弃,不在维护。所以我们只看下UDT Byte Stream的实例及Peer通信:
