ATM (Asynchronous Transfer Mode) was fast but used fixed-size cells that were inefficient for IP traffic ("cell tax"). Standard IP routing was flexible but slow.
A predetermined, unidirectional path through the MPLS network. Think of this as a virtual "tunnel."
To understand an MPLS network, you must recognize its key players: 1.MPLS History, Fundamentals & Foundational Con...
The language routers use to talk to each other and agree on which labels to use for specific destinations. 4. Why Use MPLS Today?
Prioritizing voice and video over less critical data. ATM (Asynchronous Transfer Mode) was fast but used
Allowing service providers to securely carry traffic for multiple customers over a single physical backbone.
Receives a plain IP packet, looks up the destination, and pushes the first label. Think of this as a virtual "tunnel
The core concept of MPLS is . Instead of inspecting the IP destination address at every hop, the first router (Ingress) attaches a label to the packet. Subsequent routers simply "swap" that label and forward the packet based on its value.
