While MPLS VPN are gaining ground in terms of popularity of the different protocols, there are some benefits to using point-to-point Ethernet lines
1. How MPLS (Multi-Lable Protocol Switching) Network Architecture Works Versus Point-to-Point Ethernet
Point-to-Point leased lines are formed by connecting every site to other sites using lines that are leased by service providers. Most developers use this connection for site-to-site communications. For instance, if an organization has branches in five locations, four links will be required to connect each location. For every location that’s supported, there will need to be that number of links minus one.
By contrast, an MPLS network is formed with single links to connect each location to a service provider. Any packet coming into the label edge routers will be encapsulated with an MPLS label. This is used to identify it and route it through an MPLS network. The label is later discarded when the packet comes out of the MPLS network and goes back to the individual locations.
Both protocols require the use of fiber, wireless connectivity, copper circuits, and satellite connectivity to accomplish their goals. However, the MPLS core service provider network will use high-capacity MPLS routers to facilitate the sending and receiving process to individual locations.
2. Traffic Engineering
MPLS packets are added to MPLS Edge routers to establish the path that traffic will take to travel on the network. Data, voice, and video can be set to have individual performance characteristics. VPN networks do not exhibit these characteristics. 3. Quality of Service

Since MPLS network enables traffic engineering, developers can set data traffic to a lower priority and set a real-time delay to a higher priority, which means that they’ll be less traffic and a shorter path. So, it will arrive faster. VPN Ethernet does not offer these same options. 4. Secure Connections
4. Secure ConnectionsVPN networks tend to be more secure and used by many business organizations for this reason.
Leased lines have shared connections often and may provide more opportunity for security breaches between office locations.

5. Cost Effectiveness Costs are lower with VPNs.
They have lower long-distance charges and lower support costs. A VPN can replace the long-distance dial-up services in organizations and save them money on long-distance charges. They are also less expensive than other approaches because organizations can outsource what they need from third-party service providers.

6. Network Redundancy
MPLS core network is designed to overcome individual hardware or router faults or line disconnections. The data can be re-routed to the next path to produce an optimal path with a fail-over time of 50 ms or less.
When the differences are apparent, decisions for an organization are easier. Cost reduction is one of the primary reasons companies need to know the differences. They should also be aware of which protocol is more scalable and also which has a greater bandwidth. When all of the different options are considered, a better decision can be made.
