MPLS VPNs: The Real Deal
Overview Although it seems misleading, an MPLS circuit is accurately referred to as a VPN. While an IPsec VPN creates a circuit across the Internet, MPLS creates circuits across service providers' networks. Are MPLS circuits less private because they aren't encrypted? Yes and no. Can enterprises ignore MPLS VPNs because they are a service-provider play? No. Most enterprises aren't going to implement MPLS, but increasingly service providers will provision enterprise WAN circuits using MPLS. Managing an MPLS service will likely require an end-to-end SLA (Service-Level Agreement), just as ATM and frame relay services need today. Future cool is the possibility of self-provisioning WAN circuits on demand using MPLS VPNs.
