After decades of use, enterprises are looking for MPLS alternatives. To be considered a viable alternative, a network must match MPLS service levels for predictability and consistency, while avoiding its pitfalls of cost, rigidity and capacity constraints. Although often used for WAN connectivity, the public Internet lacks the consistently low packet loss, jitter, and latency levels of MPLS. It can’t provide a predictable user experience for latency- and loss sensitive applications, such as VoIP and virtual desktops, particularly across global connections.
Affordable MPLS alternatives must enable an agile WAN, a consistent application experience on a global scale, and be delivered at a reasonable price. Deploying new sites, expanding capacity and gaining full control over network traffic, must be easier than with MPLS.
