Frequently Asked Questions
What is a WAN?
A Wide Area Network connects sites across large distances, such as branch offices to headquarters. It uses carrier services like MPLS, leased lines, broadband or cellular links.
What is the difference between MPLS and leased lines?
MPLS is a carrier-managed, label-switched network shared by many customers with traffic engineering, while a leased line is a dedicated point-to-point circuit. Cost and flexibility differ.
Why does the WAN edge need security?
The edge is where internal networks meet untrusted ones, so it is a prime target. This free intermediate Codelivly room explains how to protect it with firewalls and VPNs.
