Careful consideration should be taken when building a reliable but cost-effective network and not hoping that “luck” will prevail. The debate continues on which kind of Virtual Private Network (VPN) is the best option. (For background, check out the white paper below: “Why you still need an MPLS VPN.) There are many reasons to have Internet-based VPNs (IPSec VPN) as part of your business network. IPSec VPNs use encrypted tunnels across the public Internet for site-to-site connectivity or to connect off-net users to the company WAN. But when your business requires improved performance and not just “best effort” from the Internet, then an MPLS VPN is your answer.

MPLS VPNs are known for their reliability, protection and redundancy. They are the platform of choice for more advanced applications. Technically defined, an MPLS VPN is an on-net managed private IP service that enables fully meshed, any-to-any connectivity and application-aware networking via class-of-service (CoS) designations that dictate application priority. What that means for the business is detailed below.

What are the business drivers for an MPLS VPN solution?

Improved productivity: Less administration of daily network tasks and more visibility across the network. Track and predict usage and performance down to the applications level through web-based management tools.

Increased performance: Better prioritization and management of traffic with Class of service (CoS) capabilities, so the most important or delay-sensitive traffic — like voice and video — are delivered first.

Better control: MPLS VPNs are operated by a single network service provider. That’s important, because that provider has the ability to engineer and manage the network so that your traffic behaves in accordance with your policies and priorities.

Economies: Voice, video and data on the same access choice allow you to reduce access costs.

Security and business continuity: Fully meshed network for diversity via IP routing providing redundancy and simplified disaster recovery.

MPLS VPNs are dynamic and allow you to allocate additional bandwidth as needed or change classes-of-service settings to accommodate regularly recurring events. While IPSec VPNs can function as an efficient, stand-alone solution for certain customers, it is most often deployed together with a robust, high-performance MPLS VPN.

While IPsec does a fine job of securing data in transit, there are additional types of security and enhanced WAN services you need to run a truly business-class network that delivers the user experiences employees are expecting. Simply put, the public Internet doesn’t match the performance, reliability and security of an MPLS VPN.
