基于Qt的Windows平台组播通信技术研究

Research Of Windows Platform Multicast Communication Technology Based on Qt

鉴于Qt在开发基于组播通信的应用时无法绑定到指定网卡接收数据的问题,本文提出了一种在Windows平台下实现任意源组播和指定源组播通信的方法。本文以Windows下的Qt开发环境为基础,通过分析软件接收组播数据的特点,解决了无法绑定到指定网卡接收数据的问题,实现了Windows平台下在单网卡和多网卡计算机环境中任意源组播和指定源组播通信的技术方法。

In view of the specified network card being bound to Qt encountering in the application development of multicast communication, this paper presents a solving method of implementing the communication solution of any source multicast and specific source multicast under windows. Based on the Qt development platform, the paper analyzes the characteristics of data reception of multicast communication, and solves the problem of the specified network card being bound. Finally, the communication solution of any source multicast and specific source multicast was observed in the circumstance of signal-network card and multi- network card.
