协同设计中可靠多播通信的研究与实现

RESEARCH AND IMPLEMENTATION OF RELIABLE MULTICAST IN COOPERATIVE DESIGN

文中研究了IP多播传输中现有的差错控制方法 ,提出一种适合协同设计的可靠多播控制方法 ,利用改进的基于NAK的ARQ重传机制来实现差错控制 ,并采用反馈信息抑制技术来解决由于进行多播可靠控制而产生的“反馈内陷”问题。本方法能够实现多播数据的可靠传输 ,为协同设计系统提供可靠的多播通信支持。

In this paper, the authors first research current error control on IP multicast, then propose a new error control on IP multicast that fits cooperative design. It uses ARQ mechanism based on modified NAK, and 'NAK Suppression Scheme' was used to solve the question of feedback implosion that resulted in by credibility control. The technique can transmit multicast data credibly, which establishes a steady ground for cooperative design.
