# 带宽要求

Insight 在设计时考虑到了网络带宽的有效利用，因此，其产生的很多流量将取决于学生和教师的活动。

通常，在空闲时，每台教师和学生计算机将消耗大约 300 Kbps 的 Insight Connector 或 Teacher 控制台入站和出站流量。

查看特定学生的屏幕时，教师和学生将交换更多流量，最高可达每台计算机约 1.5 至 2 Mbps 的 Insight Connector 或 Teacher 控制台入站和出站流量。

将教师屏幕广播到多台学生计算机时，学生计算机的流量会显著增加。例如，一个教师控制台以 WXGA 分辨率 (1366 × 768) 向全班 24 名学生广播全屏视频时产生的流量介于 10 Mbps 至 50 Mbps 之间，具体取决于所显示视频的性质。
