What Is MPLS Security? Everything You Need to Know About It

MPLS network security

MPLS stands for Multiprotocol Label Switching is a multi-traffic routing mechanism. It’s a technology and protocol to transmit data between two or more locations. By using specific labels that direct packets along pre-decided path through the network, MPLS enables you to keep all the data separate from other data streams. It functions much like a switch and router that you may be currently using on your business network.

MPLS Network Security


Let’s dig out whether MPLS network security solution is the right for your business and whether it is secure.

The large-scale, IP-based MPLS has scalability and does provide cost advantages, added security and efficiency that make it really good to be deployed.

Quality of Service

One of the oft-cited benefits you can have by deploying MPLS is the ability to assign QoS features to traffic. Since it works with a system of labels, you can prioritize all the levels associated according to the needs of the hour. Other big benefit is that you can manage and control QoS. Therefore, a large number of IT companies opt for different levels of bandwidth or ports sizes and gain the ability to decide if there is congestion on this network link. They can determine what type of traffic is getting through or held up in cue for delivery later.


When it comes to more complex or the scalability of larger networks, MPLS enables you to configure the entire network automatically and set up tunnels or label-switched paths. With MPLS implementation, less physical labor or less physical resource-intensive is required for the configuration of the networks or circuits.

Protocol-agnostic nature

Protocol-agnostic nature is another advantage of MPLS. Through the MPLS, several different types of traffic are carried – irrespective of what the type of traffic is to be transported. MPLS has ability to transport anything.

To be precise, several mobile backhaul networks have different types of traffic. These traffics are transported via the MPLS routing.

For example,

  1. With 2G network, there may be some TDM
  2. With 3G network, there may be ATM
  3. With 4G, more IP-based traffic

Much More Determined Path

With MPLS implementation, you will have a much more determined path through the network from point A to point B. Because MPLS enters its own network leaving a customer’s network, it imposes labels on packets. As a result, network elements simply read the MPLS label and whisk the packet along to the next hop in a pre-determined path rather than looking up IP header information to direct packets.

Traffic Routing

Apart from the above context, MPLS provides deeper reliability and predictability of traffic within the network. Due to the fact that the Label Switched Paths are pre-determined, packets only travel along the paths you have directed them to travel upon. This greatly differentiates the MPLS routing from the IP routing. In the latter case, one packet’s path could be different from the next based on network conditions at the time. During the situation of network failure, you can easily switch over the whole path to avoid the failure, which you cannot do with the IP routing.

Hiring MPLS Network Security Service

There are many IT companies that can help you get secure, reliable and robust network services. You can find some service providers that can allow you to connect number branch offices established at different parts of the country.

When you hire a company, make sure it provides right security with restricted access to employees. Also ensure that the company will provide you with a separate virtual routing domain to segregate the company’s data and communications.

Besides, you should also make certain that the MPLS network security service provider ensures smooth and timely activation and parameters that cover delay, availability, packet loss, helpdesk support, proactive monitoring and real-time performance reporting.

Remember that there are some MPLS networks that integrate VPN connections for additional security and encryption. Be sure to ask your service provider whether their MPLS provides any added security/encryption for your packets on their network.

To conclude, a large number of companies are moving away from legacy networks to MPLS network security. So look for a trusted company and implement MPLS mechanism.
