高效的网络接口已成为多机系统中的重要技术之一。文中通过对当前各种接口类型的分析认为，紧耦合应是网络接口的方向；同时，不同类型信息的串行处理是网络接口进一步提高性能的瓶颈。为此，对不同信息间的并行性进行分析后，提出了并行网络接口的概念结构，并对其性能进行了评价。 Efficient network interfaces have become one of the most important technologies in multi-machine systems. In this paper, the current analysis of various types of interfaces that the tight coupling should be the direction of the network interface; the same time, different types of serial data processing is the network interface to further enhance the performance of the bottleneck. Therefore, after analyzing the parallelism of different information, the conception of parallel network interface is put forward and its performance is evaluated.
