文中介绍了一种新型的高性能网络接口（ＨＰＮＩ）的设计与实现．ＨＰＮＩ网络接口通过一个表直接由硬件对通信缓冲区进行维护，可以直接将消息数据从应用空间输入／输出到网络，从而支持真正意义上的０ 拷贝通信协议．通过提供用户层网络访问接口，重叠通信与计算等手段，该接口取得了很高的通信性能．其中实际测量的应用程序之间１６ 字节消息的传递延迟不到３μｓ，最大持续通信带宽可达４０ＭＢ／ｓ．
This paper introduces the design and implementation of a new type of high performance network interface (HPNI). The HPNI Network Interface maintains communication buffers directly from hardware through a single table, allowing message data to be input / output directly into the network from application space to support true 0-copy communication protocols. By providing user-level network access interface, overlapping communications and computing tools, the interface has achieved high communication performance. The actual measurement of applications between 16-byte message delivery delay of less than 3μs, the maximum continuous communication bandwidth up to 40MB / s.
