Which one is better

Hi @DANIH

If you're looking for the best option in terms of security (it depends on your ISP, so make sure to get good SLAs), scalability and speed then the best option is L2VPN (VPLS).

You can find more details about these solutions in the following link:

Here are five factors to consider in the MPLS vs. VPN vs. leased line debate.
1. COST. Leased lines are the most expensive. VPNs are less costly and come in multiple flavors – layer 2 VPNs are more secure, layer 3 VPNs are faster to deploy and less expensive but exposed to the risks and congestion of running over the public Internet. MPLS increases efficiency compared to relying on IP-based routing.

2. SECURITY. Leased lines win out in terms of security, as they are dedicated only to a specific customer’s traffic. VPNs over the public Internet are the least secure. MPLS falls somewhere in the middle, as it emulates the “feel” of a dedicated line but still relies on shared network elements. MPLS has no inherent encryption and its security depends heavily on the network core being secure, according to Professor Jose Santos of the University of Colorado at Boulder’s Telecommunications Department.

3. RELIABILITY. Again, leased lines come out in front. VPNs can be subject to the variability and congestion of the open Internet as traffic makes its way from one network point to another, as it shares the virtual road with other traffic. MPLS allows prioritization of traffic and establishment of quality of service levels, including the definition of fallback paths to ensure reliability in the event of outages within the network requiring traffic to be re-routed.

4. SCALABILITY: Leased lines are the most difficult to scale, both because of the time needed for deployment and the expense. Layer 3 VPNs are quick and easy to deploy, but can become complex to manage as a business grows. MPLS is widely accepted as an efficient technology that is easily scaled.

5. OPERATIONAL DATA NEEDS: This includes the question of the type of data flowing and the business’ network needs. Does the business require only point-to-point communication between two locations? Point to multi-point? A mesh network covering multiple locations, where each branch must be able to communicate with all others? Leased lines again fall to the rear in terms of easily addressing complex network needs, particularly for medium-sized businesses. MPLS has both point-to-point and one-to-many capabilities for communication.

It will depends base on deployment scenario; however, L2VPN-VPLS  will provide robust security and flexibility to run services over 3rd party network.  

MPLS L2VPN provides a layer 2 connection between CEs. In a L2VPN network, it's not necessary to switch customers' routes with PE router, so it provides a better privacy and low resource cost on PE route. Besides, L2VPN provides the layer 2 connection, it allows the users to run more protocols which run on layer 2 link, while L3VPN doesn't.

MPLS L3VPN provides a layer 3 connection between CEs. Since VRF is required on PEs for each CE in L3VPN, so it will requires more hardware resource than L2VPN does.


On ther contrary, International Private Leased Circuit (IPLC) is a point-to-point dedicated leased line between global offices creates a robust information superhighway that ensuring offices located in different countries stay connected.  Making it ideal for organizations that have high traffic volume between overseas sites.
