摘要： 信息爆炸是传输层的多播协议设计中普遍存在的问题。简要介绍了解决信息爆炸问题的几种常用方法，提出了一种新的方法。此方法综合了延迟法、周期法和轮询法，在避免信息爆炸的同时对提高协议性能也作了较深入的考虑。

Abstract: Reliable sender-based multicast protocols do not scale well due mainly to implosion caused by excessive rate of feedback packets arriving from receivers. The paper presents a novel way of circumventing this problem after an introduction of some widely used methods. The technique fuses three categories: delay-based, period-based and polling-based, which improves the protocol performance while avoiding implosion.
