Nowadays, data center security is becoming more and more important for enterprises and data center networks. Therefore, it is necessary to maintain data security when storing, processing or transmitting data between network devices such as optical fiber switches, storage servers and so on. Now, VPN and MPLS are two competitive technologies to maintain data storage and efficient security. But what is it and how different are they? SPOTO will introduce the difference between VPN and MPLS in detail and explain how to make the correct decision through VPN and MPLS.
VPN vs MPLS: What Is VPN?
A VPN, also known as a virtual private network, is essentially a virtual network in a physical network. It is usually deployed as a high-security network tunnel, which is transmitted in a highly encrypted form. Thus, any data transmitted through the VPN is not visible to the physical network around it. The VPN can be created by various types of encryption, such as IPsec, SSL, and TSL. In which ipsec is the most widely used.
VPN vs MPLS: What Is MPLS?
MPLS is an abbreviation for multi-protocol label switching, which is a protocol that uses tags to route packets instead of IP addresses. It is a technology to boot and transmit data between network nodes, which means that direct virtual links can be created between different nodes regardless of location and distance. Unlike VPN, MPLS is a mechanism independent of protocols and data, so it can work regardless of the physical network topology. Because of this flexibility, many vendors have developed network switches suitable for MPLS platform.

VPN vs MPLS: What’s the Difference?
VPN and MPLS are not only different in the above aspects, but also in terms of cost, performance, application, and so on. It is clear here that the difference between VPN and MPLS is shown in the following figure
VPN vs MPLS: Which One to Choose?
Both VPNs and MPLS have their advantages and disadvantages. Therefore, before deploying a VPN or MPLS network, it is best to perform a cost-benefit analysis to help you make a decision. In fact, choosing a VPN or MPLS depends on your business needs, which can be attributed to factors such as cost, security, availability, QoS, speed, and so on. For example, if your company runs critical real-time applications (such as voice, video, or remote desktop) on the network, MPLS is a perfect solution. While VPNs are suitable for those who want cost savings and are less demanding for QoS, speed, and the like.
