I'm conducting a little survey regarding the adoptation of the inernet
as a transport layer (using VPN) for branch offices connectivity (not
remote workers)

I'll be glad to get some feedbacks on the following
1. Is this already happening in large organization (200 branches and
2. What's missing (reliability, SLA, etc)
3. is DSL/cable an real option?
4. what do you prefer MPLS or the Internet?

Thanks in advance, this is great help to me
