Greetings,
I am actually working with a company that will be offering a product with an
SLA over the internet. One caveat is that you can not be more than one ISP
away from the company on either end. They will be using GRE tunnels to the
ingress router, then they will create MPLS Traffic Engineering Tunnels (TE)
to transverse their network to the egress router and finally GRE tunnels to
far end customers site. They have built a nationwide fiber optic network to
support this product and it should be interesting to see if businesses
choose to pay a premium for the SLA.
Thanks,
Jeff
