基于Windows套接字编程的网络编码仿真实现

针对网络编码数据传输技术,采用Windows套接字编程工具,提出了一种仿真实现方法。在局域网内选取若干个终端模拟网络节点,逻辑上构成一个单源组播网络,各终端上采用socket套接字编程方法,按照网络编码数据传输策略进行收发数据。给出的例子是典型的蝴蝶网络,但容易扩充到一般的单源组播网络。与已有的网络编码仿真器相比,提出的方法具有简便、易于掌握的特点。

Simulation Implementation of Network Coding Based on Windows Socket Programming

By use of Windows socket programming,a method of simulation implementation of network coding is proposed.In a local area network,some terminals are selected to simulate the network nodes logically to form a single source multicast network.With adopting socket programming,the terminals send or receiver data according to the data transmission strategy of network coding.The illustrated example is a typical butterfly network,but can easily extend to general single source multicast network.Comparing with the existing network coding simulator,the proposed method is simple,convenient and easily to be mastered.
