What is MPLS and how does it work?

How does MPLS work? First, we can analyze how “normal” network routing works. When you visit a website in your browser, there are many processes involved. Requests from your network are divided into small chunks called packets. Each packet carries information about their origin and their destination. Routers send packets to other routers, and that's how they move across the internet. Even though two packages can travel to the same destination, they can take different routes to reach the same location. And how does MPLS work? MPLS is a data forwarding system that assigns labels to each packet. These labels determine how a packet should travel, creating a private network.

Since packets are labeled in the transition between layer 2 (responsible for transferring data between nodes) and layer 3 (which performs routing and forwarding of packets), MPLS is generally called a “layer 2.5 protocol”.

Dec 27, 2021 · 7 min read The pros and cons of MPLS Pros Speed: Because packets in MPLS networks travel along predetermined routes, routers do not need to do IP checks at each step. This means that the entire routing process consumes fewer resources compared to “normal” routing. MPLS can be beneficial if speed is an important factor, especially for running real-time applications.



Quality: MPLS has QoS options that help packets achieve better performance and efficiency when traveling across the network. Remote connection: Because MPLS is cloud-based, you can add new remote connections without having to invest in additional hardware. Reduction of network congestion: MPLS divides web requests between different routes, avoiding bottlenecks and network congestion. Improved uptime: If a period of downtime occurs, MPLS can change traffic to an alternate route if available. Cons User experience: MPLS requires extensive configuration on your router. Setting up an MPLS network on your own is only recommended if you know what you are doing. Otherwise, leave this task to an IT professional. High cost: MPLS solutions can be expensive, as you need to pay monthly for data.
