Difference Between Virtual Private Network (VPN) and Multi-Protocol Label Switching (MPLS) - GeeksforGeeks (2024)

Virtual Private Network (VPN) and Multi-Protocol Label Switching (MPLS) are two networking technologies that allow for secure and efficient data transmissions. VPN is a secure connection which is established over a public network connection enabling users to remotely access private networks with encrypted information being sent through it.

On the other hand, MPLS refers to a method of routing data traffic effectively across a private computer network based on a labeling system for controlling the movement of information thereby ensuring the Quality of Service (QoS). The two technologies serve different functions and thus have different requirements depending on the type of network in question.

Virtual Private Network (VPN)

VPN is for virtual private networks, is a network type that is a private network but virtual. By applying VPN we can use public network as a private network as VPN is a tool of handling encryption, integrity protection and certification or authentication. It emulates a private network over a public network. This allows users to remotely access a private network. Unlike MPLS, In VPN, routing divisions and traffic are handled by the customers. In a VPN, all OSI layers are required to make a VPN functional.

Advantages of VPN

• Cost-effective: VPN is generally less expensive than MPLS because it uses existing internet connections.
• Flexible: VPN is flexible and can be used with a variety of devices and operating systems.
• Scalable: VPN can be scaled to support large numbers of users.
• Remote access: VPN allows remote access to a company’s network, making it easy for employees to work from anywhere.
• Easy to set up: VPN is easy to set up and configure, making it accessible to small businesses and individuals.

Disadvantages of VPN

• Security risks: VPN can be vulnerable to security risks if not set up properly, leaving data and networks exposed to hackers.
• Lower reliability: VPN may have lower reliability than MPLS due to the dependence on the public internet, which is subject to outages and other issues.
• Lower performance: VPN may have lower performance than MPLS due to t

Multi-Protocol Label Switching (MPLS)

MPLS is for Multi-protocol Label Switching, is a crucial data-carrying system. Its capabilities are quite much like the packet-switched network and circuit-switched-switched network, in which it simulates the some features of a circuit-switched network at packet-switched network. In MPLS, label switching method is used to assign each packet with a number or label. The label or number on each packet plays an important role in packet forwarding process. MPLS operates on the layer 2 and layer 3 of OSI (Open Systems Interconnection) model. MPLS is a higher reliable technology since, it assures the Quality of Service (QoS).

Advantages of MPLS

• High reliability: MPLS provides high reliability and quality of service because it uses dedicated connections rather than the public internet.
• High performance: MPLS provides high performance and low latency because it uses dedicated connections and does not require encryption and decryption of data.
• Scalable: MPLS can be scaled to support large numbers of users and traffic.
• QoS: MPLS supports quality of service (QoS), which enables traffic to be prioritized and managed to ensure that critical applications receive the necessary bandwidth and latency.
• Better security: MPLS provides better security than VPN because it is not subject to the same vulnerabilities associated with the public internet.

Disadvantages of MPLS

• Higher cost: MPLS is generally more expensive than VPN because it requires dedicated connections.
• Limited flexibility: MPLS is less flexible than VPN and may require specialized hardware or software.
• Longer implementation time: MPLS may require longer implementation times than VPN due to the need for dedicated connections and specialized hardware or software.

Similarities Between Virtual Private Network (VPN) and Multi-Protocol Label Switching (MPLS)

• Both technologies can be used to create secure private networks.
• Both technologies can be used to connect geographically dispersed sites and remote workers to a central network.
• Both technologies use encryption to protect data during transmission.
• Both technologies can prioritize traffic and provide quality of service (QoS) to ensure that critical applications receive the necessary bandwidth and latency.
• Both technologies can be used to create a secure connection over a public network.

Difference Between Virtual Private Network (VPN) and Multi-Protocol Label Switching (MPLS)

Conclusion

VPN and MPLS are two different technologies used to create private and secure connections between devices or networks. VPNs use encryption and tunneling to create a secure connection over the internet, while MPLS creates a private network over a shared infrastructure. VPNs are generally used for remote access and site-to-site connections, while MPLS is used for private network connections between two or more sites. Understanding the differences between these technologies can help you choose the right solution for your specific needs.

Virtual Private Network (VPN) and Multi-Protocol Label Switching (MPLS) – FAQs

What is the primary function of a VPN?

A VPN creates a secure connection over the internet, allowing users to access a private network remotely while encrypting their data to ensure privacy and security.

How does MPLS improve network performance?

MPLS enhances network performance by using label-based routing to efficiently manage data traffic, reduce latency, and provide consistent Quality of Service (QoS).

Can VPNs and MPLS be used together?

Yes, VPNs and MPLS can be used together in some network configurations to leverage the benefits of both technologies—VPN for remote access and MPLS for reliable internal network traffic.

Which technology is better for remote work: VPN or MPLS?

For remote work, VPN is generally better suited as it provides secure access to the network from various locations. MPLS is more suited for maintaining high-performance connections between fixed locations within a private network.
