MPLS vs. VPN: What Is the Difference?

Security
Choosing between an MPLS or VPN solution is tough. Read our comparison to decide which works best for you.

Average internet users are increasingly more aware of the threat they face online—the very same threat that has materialized so many times in the past in shape of data leaks, botnet attacks, cloud hacks, social media coercion and nation-level intervention.

The term VPN has almost become synonymous with security and online anonymity.

Users now have the choice between two similar technologies, albeit serving a different purpose—MPLS and VPN.

Both sort of do the same thing, but what really differentiates them is their intended purpose and what they achieve.

Read on to find out what they are and how they’re different.

What Is a VPN?

VPN, which stands for Virtual Private Network, is a technology which acts like an actual private network regardless of whether the devices are physically connected through a single network or not.

It was developed to cope with situations where devices had to be connected over a long distance where setting up the physical network is almost impossible.

The concept of security in the Internet
VPN enables a network to extend over multiple networks, even public ones, and keeps the network’s integrity in tact by encrypting all the traffic.

While connected to the network through a VPN, the user experiences being part of the network as if they were physically there, despite being in a different country. This solves the problem of connecting remote users to the private network.

VPN enables a network to extend over multiple networks, even public ones, and keeps the network’s integrity in tact by encrypting all the traffic.

The identity of the remote users is hidden as well as the traffic. For the public network, the user location is masked to appear from the location of the network server. This is achieved by making a virtual tunnel between the server and the user where the data is masked before being entered in the tunnel and is decrypted on the other side where the user is.

The tunnel bridges through the public networks and secures the data, along with destination points, from being seen.

There are multiple types of VPNs, but the most common is the mobile VPN. In it, the server has a fixed point, however the service is set to be able to cater for a user having a variable IPs.

VPNs are currently in high demand due to their ability to encrypt traffic and keep users’ identity safe.  

What Is MPLS?

MPLS, unlike the VPN, is not a technology. It is a technique to route data efficiently between large networks.

Multi-Protocol Label Switching does not follow the conventional method of searching for IP addresses in IP tables while looking for target device one by one. It simply searches for logically named short path labels and simply points to the end target. Each label corresponds to a complete path.

Usually, the packet to be routed is required to be read before deciding its route, however, in MPLS, this doesn’t happen. The packet is routed on a path identified by the label in an MPLS header. These paths are between network nodes instead of endpoints.

The multiple protocol support and efficient routing enable the network designers to create network circuits without worrying about the protocols to use.

Since the reliance for the path is on labels instead of IPs, the data packets are encapsulated while being sent over the network. These packets may belong to multiple protocols, hence the name.

The multiple protocol support and efficient routing enable the network designers to create network circuits without worrying about the protocols to use.

The following factors are what enables MPLS to be easily scalable over any kind of network type, location and size:

  • Encapsulated data
  • Usage of nodes instead of IP
  • Multiple protocols
  • Independence from the underlying network topology
  • Number of networks
  • And data

These are also the very same reasons it is also used to create a VPN.

MPLS also supports multi-level priorities for the existing connections. This makes it a good choice for organizational use where control of network traffic needs to be priority-based.

Mobile VPN vs. MPLS

Now that we know what VPN and MPLS are, and how they both help send data over an extended virtual network, let’s now look at how exactly they achieve this by pitting them against each other:

Attribute Comparison

Attributes VPN MPLS
Technology Type Point to Point and Multipoint technology. Multipoint technology
Encryption Uses encryption Not encrypted by default. Can be encrypted with additional overhead
Prioritized data
traffic
Not possible Possible
Platforms Support Supported on any smart devices along with routers. Supported by any of the OSI layer 3 devices
Multicast Support No Support multicast traffic
Cloud-Based
Services
Yes Limited
Cost Less (individual-based) Expensive(organization based)
Good for Best for an individual to small scale businesses Suitable for large-size enterprises
Setup and
Management
The user is responsible. Choose and install your own preferred service. Shared responsibility of user (organization) and the internet service provider.
Traffic Control and Routing Decision User dependent. Based on ISP
Footprint(locations limitations) Based on internet availability. Anywhere. Depends upon ISP footprint or business partner’s availability in desired locations.
Traffic speed/
critical data loss
Less reliable Reliable, quality of services is a contract.
Setup time and
difficulty
Touch of a button Depending on ISPs availability, quick and fast.

 

Pros & Cons

VPN

PROs CONs
Economic Network connectivity issues
Easy to setup Data latency and time lag
Not possible  
AES 256 bit encryption  
Anonymity  

MLPS

PROs CONs
Fast routing Expensive setup cost
Prioritized traffic – bandwidth
choices
Data and responsibility shared with the ISP
Dependable quality services Not encrypted by default
Fast routing  

Finally

It all comes down to individual needs and the purpose of the technology to be selected. On paper, the VPN seems like a great choice for individuals looking for security.

Research and choose a top quality VPN that best suits your requirements.

Business/organizational users will benefit more by looking for a good ISP providing good MPLS-based VPN.
