MPLS network can be bought from a telecommunication service provider. MPLS can answer many network problems, like speed, traffic engineering, Class of Service etc. It is an advanced form of ATM where multiple Layer 3 protocols are used to transfer data. MPLS provides many advantages over the traditional networking technologies and is known to reduce the workload of network operators tremendously.
MPLS Virtual Private Networks
MPLS VPNs are maintained on the equipment of service providers, hence MPLS networks are very cost-effective and more profitable as compared to VPNs working on other technologies. MPLS VPNs keep different
customers’ traffic separate by uniquely identifying each VPN flow and setting up circuit-like connections.
