Unicast, multicast and network disruption
I run a student lab that has 25 desktops running XP Pro. I'm considering switching from Ghost to Snap Deploy but I have some questions. When using a Ghostcast server, our network monitor always calls saying that the Ghostcast session which is configured to use 'Direct Broadcast' disrupts the network to the extent that they aren't even able to monitor the main router that services the entire School of Medicine. I've tried changing to Unicast and Multicast but I think the same thing happens. I can't remember but I think I use 'Direct Broadcast' because it's faster than the other two.
Can I expect the same problems with Snap Deploy? All our network routers and switches are Cisco but I know nothing about managing them or what it would take to diminish the chances of the type of broadcast storm that I experience when deploying windows to our student lab.
Is there anything that can be done to eliminate this problem or is it a architecture issue? By that I mean, do our network people need to figure out a way to segment us from the main backbone when it's time to do a deploy so to not take down the network? I guess it's like a denial of service attack.
