FAQs & disclaimers

What is the primary difference between MPLS and DIA?

MPLS provides a private, isolated network path, often managed by a single provider, ensuring high reliability and Quality of Service. DIA offers a dedicated, uncontended on-ramp to the public internet, providing guaranteed symmetrical bandwidth and strong Service Level Agreements for cloud-bound traffic.

Why are enterprises moving away from pure MPLS networks?

Traditional MPLS networks were designed for hub-and-spoke traffic patterns. With the rise of cloud computing and SaaS, a significant portion of traffic is destined for the public internet. Forcing this traffic through a central data center via MPLS (backhauling) creates bottlenecks, increases latency, and is inefficient, leading to the 'Great MPLS Disconnect'.

What role does SD-WAN play in modern enterprise networks?

SD-WAN acts as an orchestration layer, intelligently managing and directing traffic across multiple transport types, including MPLS, DIA, and broadband. It provides flexibility, improved application performance, and centralized control, enabling a hybrid network architecture that optimizes cost and performance.

What are the hidden costs associated with network migration?

Hidden costs can include local loop fees (the physical connection to the provider's network), early termination fees for existing MPLS contracts, the expense of running two networks simultaneously during migration, and additional investments in security solutions like Next-Gen Firewalls for DIA-based networks.
