在这个结构中提出的另一个方法是协议的性能，当卫星没有在两个未被占用的频率集的交集中没有频率时。

Another proposed approach in this architecture is the behavior of this protocol when no frequency was found by the satellite in the intersection of the two free frequency sets.

但一致性协议的使用也将占用系统资源，影响程序的运行速度。

But the memory consistency protocol will use system resources, has effect on system performance.

在典型的组播网络系统模型基础上，对这两类协议以及一种主要的改进协议在占用网络带宽和可扩展性方面的性能特点进行了定性的分析和比较。

Qualitative analysis of these two basic protocols and a modified protocol is given to exhibit their characters in scalability and bandwidth usage on a typical multicast network model.
