BSNL is in the process of commissioning of a world class, multi-gigabit, multi-protocol, convergent IP infrastructure through National Internet Backbone-II (NIB-II), that will provide convergent services through the same backbone and broadband access network. The Broadband service will be available on DSL technology (on the same copper cable that is used for connecting telephone), on a countrywide basis spanning 198 cities.
In terms of infrastructure for broadband services NIB-II would put India at par with more advanced nations. The services that would be supported includes always-on broadband access to the Internet for residential and business customers, Content based services, Video multicasting, Video-on-demand and Interactive gaming, Audio and Video conferencing, IP Telephony, Distance learning, Messaging: plain and feature rich, Multi-site MPLS VPNs with Quality of Service (QoS) guarantees. The subscribe will be able to access the above services through Subscriber Service Selection System (SSSS) portal.
The Broadband 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.
The Broadband Service has been launched in Bangalore, Chennai, Hyderabad and Kolkata from 14th January 2005. Soon, it will be extended to more than 200 cities.
