MPLS: MultiProtocol
Label Switching
Initially, the objective for developing the Internet was purely to transport data from
one terminal to the other without considerations for QoS management (best effort
was the aim), speed, scalability, and traffic engineering. As time progressed, the
need for QoS increased, leading to protocols such as MPLS (MultiProtocol Label
Switching). e original driver for introducing the MPLS was to make routers
faster. It was observed that ATM switches, which used virtual path switching, were
