BSNL Broadband is an Internet access service from state-owned Bharat Sanchar Nigam Limited (BSNL) available in India since 14 January 2005. Until 30 September 2007 it was known as Data One.
BSNL is commissioning a multi-gigabit, multi-protocol, IP infrastructure through National Internet Backbone-II (NIB-II), that will provide services through the same backbone and broadband access network. The broadband service will be available on digital subscriber line technology (on the same wire that is used for plain old telephone service), spanning 198 cities.
NIB-II would have put India at par with more advanced nations. The services that would be supported include 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, multi-site MPLS VPNs with Quality of Service (QoS) guarantees. The subscribers would have been able to access the above services through Subscriber Service Selection System (SSSS) portal.
The service will be given through Multi Protocol Label Switching (MPLS) based IP infrastructure. Layer 1 of the network will consist of a high-speed backbone composed of 24 core routers connected with high-speed 2.0 Gbit/s(STM-16) links.
