The Service will be given through the state of the art Multi Protocol Label Switching (MPLS) based IP Infrastructure, which is designed to provide reliable routes to cover all possible destinations within and outside the country. Layer 1 of the network will consist of a high speed Backbone comprising of 24 powerful Core Routers connected with high speed 2.5 Gbit/s(STM-16) links. The routers are located on the national DWDM network interfacing at STM-16 optical level to provide for high transmission speeds.MPLS VPN is a technology that allows a service provider like BSNL to have complete control over parameters that are critical to offering its customers service guarantees with regard to bandwidth throughputs, latencies and availability.
