CBC Question

Hi,

I work at a school and currently we have an EVPL that is 10/10Mbps down/up. This is simply not enough bandwidth for where the school is headed. I am trying to talk the tech director into getting comcast business class (which would be 1/3 of the cost we pay now) rated at either 50/10 or 100/10Mbps. The rep we use that provides the EVPL says that once we get more then 70-80 users on the Comcast business class copper line that it will saturate and would end up being slower then the EVPL.

I just can't see how thats possible when currently, when school is in session I'm lucky to download at 100kbps. Hell my home comcast connection puts this to shame, but before going to the principle and fighting for this, thought some people might have some insights here. Any drawbacks to using Comcast Business class with 100+ users? Eventually I would like to scrap the EVPL and just use CBC with an ATT Business DSL on a load balancer for failover. That would be about half of what we pay now for ten times the rated speed.

Any other comments or suggestions would be appreciated. Thanks.
 
salesmen making junk up... not surprising...

you get the LAN connection for the SLAs and reliability... not for speed or concurrent connections imo...

maybe if you use their crappy provided router i could see that happening, but not if you use cable modem in bridge mode and route yourself...

i think cable + DSL and a load balancer would be a good replacement for that LAN connection...
 
Thanks for the replies. I was thinking that, but just wanted to get some other opinions before I went for it. The LAN connection over the EVPL has never went down in my time here ... so its very reliable, just very slow in comparison to other options.

In response to the load balancer, was probably going to go with http://www.peplinkworks.com/Balance-380.asp
 
Is it required that fast downloads be available at the school, or could you restrict the bandwidth usage with a solid firewall solution?

If these are school terminals where occasional streaming of content may occur I'd probably limit each connection to 1mbit or so, which should help mitigate the occasional spike in usage coming from several terminals performing such actions simultaneously. I'd also aggressively filter specific sites (i.e. porn, 4chan, etc.) and severely restrict anything non-scholastic (heck I might even lock the damn things down to only use port 80, depending on what's required.) Facebook during school hours? Heck no! :)

The load balancer solution is also something that could help, but remember that Comcast Business Class has no SLA (or, rather, there's no uptime guarantee as part of any SLA you sign.) I've had it here at my company for the past several years and, while the speed is pretty solid, when it's down it takes upwards of 8+ hours for the network to come back up. If it's after-hours you're lucky to have a guy out there before morning to look at the problem, but they are pretty good about ensuring SOMEONE is looking at your problem before the next business morning.
