在线课堂:VSat、租用线路还是其他?
我的一位朋友正计划建立一个在线课堂环境,目前正在评估他可以拥有的各种 ISP/连接选项。尽管他确实需要 100% 的互联网连接正常运行时间,但为了获得良好的互联网速度,可以将其折衷为 99.X%。此外,由于他刚刚起步,“价格”也是一个限制,但质量不应受到影响。
VSat 链路是我们知道可能可行的选项之一,但我在谷歌上搜索 VSat 链路与租用线路相比的好处时感到非常困惑。我觉得一条2MBPS的专线(可能是2条)就足够了。
正确的连接应该是什么?有什么想法吗?
One of my friends is planning to set up a online classroom sort of environment and currently is evaluating the various ISP/Connection options he can have. Though he certainly needs a 100% up time of the internet connection, it can be compromised to like 99.X% for a good internet speed. Also since he is just starting up, 'price' too is a constraint but quality should not be compromised.
VSat link is one of the options that we know that might work out but I am very confused googling on the benifts of a VSat link as compared to a leased line. I feel a 2 MBPS leased line(may be 2) can suffice.
What should be the right connection? Any thoughts?

如果您正在进行任何交互操作,VSat 将会出现明显的延迟。它还容易受到天气影响(暴风雨、雪,会影响链接的质量)。另外,您是在偏远地区还是发展中国家?如果不是,那么您应该使用一些商业 DSL 线路。
VSat is going to have a noticeable delay if you're doing anything interactive. It's also prone to weather (heavy storms, snow, can affect the quality of the link). Also, are you in a remote area or a developing country? If you're not, then you should just go with some business DSL line.
