Why Businesses prefer MPLS over IPsec Service

It may appear that corporate WANs only need IPsec encryption with a few access mechanism for Internet functionality. However, this will likely fail to meet the up-time, capacity and performance requirements of most applications. The Internet generally treats all data traffic the same and IPsec offers only basic security and reliability, so here are 5 reasons why companies prefer MPLS solutions.

Basic vs. Enhanced Service

Businesses can encrypt data for transition protect over the Internet using standard protocols like IPsec. These generic solutions for consumer-level broadband connection will be less expensive than MPLS solutions. Regardless of whether there is IPsec encryption, most Internet providers tend to transport data packets with no quality of service (QoS) enforcement. This means that there may not be uptime guarantees, multicast capabilities and distributed denial of service (DDoS) attack resistance. Unless a business only plans on using email and file transfers, they will need to MPLS to take on today’s dynamic traffic patterns and converged applications.

Security Management

IPsec VPNs offer protection against in-transit data breaches across the Internet using industry standard encryptions. MPLS VPNs transport data across the WAN infrastructure by segmenting and labeling specific traffic advanced tagging technology.  Data label switching can best be described as carving out a private WAN tunnel for each customer. MPLS VPNs are not susceptible to DDOS attacks, which are increasing at 125 percent per year. MPLS-protected IP addresses can’t be hijacked and used as spoofed source addresses because of the high levels of segmented encryption.

Business Traffic Requirements

Businesses and capacity limitations don’t mix. A single commercial connection isn’t capable of supporting converged applications and multimedia traffic. Video is the fastest growing traffic generator, but it will impede other traffic and overwhelm consumer-level broadband connections. As a result, many companies end up purchasing and managing multiple connections to enhance capacity during peak traffic periods, which is quite costly and complex. IPsec connections tend to reflect the static point-to-point and hub-and-spoke traffic patterns of the past. Global users with collaborative needs and multimedia apps now require real-time communications. Business-class network services need enhancements that guarantee the securest data transport.

Direct Site-to-site Connectivity

Any-to-any connectivity enables business sites, remote visitors and mobile users to directly exchange data, voice and video traffic with one another. IPsec services and general-purpose Internet providers usually require traffic to pass through a central site to reach the preferred destination, which slows performance. Class-of-service (CoS) and any-to-any connectivity maintains performance flows, so they are ideal for business applications and real-time voice and video apps. More and more businesses are relying on social media, instant messaging and teleconferencing to collaborate with peers and provide customer service, so they need network performance stability.

Operator Control and Management

MPLS VPNs are operated by a single network service provider, so they can manage traffic and engineer the network to intuitively respond to the client’s needs and priorities. The public Internet is a confusing conglomeration of varying service providers, who each control their own segment. Once traffic passes over an ISP border, just like state and national borders, it loses any associated rights and handling specifications. Most ISPs cannot control downtime, predict problems or escalate service degradation when the root cause is an area of the Internet owned by different providers. MPLS solutions offer infrastructure redundancies for business continuity, which reroute around failures in just milliseconds.

MPLS solutions prioritize and manage traffic so that the most urgent and delay-sensitive traffic is delivered first. IPsec connections can’t efficiently send multicast communications to multiple select nodes and do not offer any bandwidth savings with point-to-point tunnels.
