VPN and MPLS are network solutions designed to provide reliable and secure connectivity across distributed locations, enabling enterprises to work efficiently. When deciding which one is best for their needs, the enterprise must consider several factors such as cost, security, availability, QoS, speed, etc.
MPLS is a great solution for those who demand high-speed performance. This technology offers a quality of service (QoS) guarantees that prioritize applications like voice and video to optimize overall performance. It also provides an extra layer of security, with all traffic routed over the private backbone of a provider. The drawback here is the high costs associated with MPLS services.
