Companies selecting IP VPN architecture - MPLS, IPSec, and SSL - need to consider their business needs because there is no single best choice. In fact, many enterprises are best served by some combination of the three architectures. IPSec and SSL VPNs, in contrast, are typically managed by the enterprise, and originate and terminate at the CPE. IPSec- and SSL-based VPNs are also available as a managed service from certain service providers. This white paper describes each Layer 3 IP VPN architecture - MPLS, IPSec, and SSL - and explains each technology's strengths and limitations, and suggests when it might be the best choice for an enterprise. The paper concludes with a table that compares and contrasts the architectures.
