I have 200 sites at various locations throughout the US and these are connected to a data center thriugh a hub and spoke model. But these 200 sites are broken down into different regions and those go to a central hub for that location, for eg. North East region will have 10-15 sites connected to a router which then gos to a frame relay and an ATM network and then to the data center.
So now I have 200 sites, 10 hub sites and 1 data center.
What should my ideal Network Design look like?
Should I not use central hub regions and connect each site individually to the data center? Then would it be a problem to have 200 virual circuits and any PVC issues?
