Site-to-site connectivity: MPLS vs. IPSec

Since the late 1990s, the popularity of site-to-site VPN has risen dramatically, especially as broadband Internet has spread and costs have come down.

Download this article, which contains a handy comparison chart, to learn what MPLS is and how its features and functionality stack up against site-to-site VPN connectivity.
