I hope my question is fine for this group, and if not, I'll remove it as soon as required. Hereis a shot description of our problem:
- Our system has many clients (about 500) that should be updated via WiFi 802.11b through the same ftp server.
- We can't modify the network setup (i.e. we can't use 802.11g/n client) but we can update firmware on the peers.
- The size of the update is 200 MB and the clients access.
- the clients can't be updated in different slice time, since they wake up and shutdown almost at the same time.
Since ftp unicast connections are a bottleneck, we are evaluating a multicast over WiFi approach. (something similar to the way TV producer use DTV channel to transmit firmware updates)
However I didn't find, on the web, many information about this idea on WiFi. I found something about broadcast video streaming, but nothing more. Is there someone that can provide me an idea, a well documented protocol in order to implement such a system? Furthermore, is there someone that, if so, can explain where our approach is wrong? Thanks a lot Giovanni
