I'm trying to understand how VPNs are "commonly" being deployed across an MPLS network. - As I understand it, there are two basic flavors of MPLS-based VPNs: BGP/MPLS VPNs and ATM-like VPNs using LSPs like virtual circuits. Is this correct? Could someone clarify the distinction for me? - What order of VPNs can a high-end PE support (hundreds, thousands, ...)? - What percentage of LSPs originate on the CE vs. the PE? - What efforts do service providers make to engineer the mapping of VPNs over LSPs, e.g., for load balancing or satisfying QoS requirements? Are there common ratios of VPNs to LSPs? How often do VPNs get dedicated LSPs? How common is it that there are multiple LSPs to select from between an ingress-egress pair, and how are VPNs partitioned over those?
