eclass learning and video streaming

We have problem on internet performance when running a elearning class. In case we can upgrade our bandwidth, is there any free solution to improve the current situation, say proxy server or some other solution ?

I think you mean "In case we cannot upgrade ..." instead of "In case we can upgrade ...".

Without extra bandwidth, a proxy will not help you improve performance / throughput - it will only lower your performance because the proxy is an extra step between you and the content.

Lowering your video stream quality will help, see if you can change (lower) that in your elearning environment.

I'm thinking of proxy to cache to video for the first time and then deliver it to the other workstations locally...

Does it improve in performance in this way ? Tks

With a properly configured cache (like squid for example), this is possible. Squid can be configured to cache youtube video's (ref: link). There are also commercial video cache services available, depending on your budget. The most easy solution would be that you 'download' the videos to a local server and then point the workstations to the local server. This all depends on whether you are allowed to cache (copy) the elearning material. Be sure to check the course TOU for that.
