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.

-
To provide high speed Internet connectivity (upto
8 Mbps)
-
To provide Virtual Private Network (VPN) service
to the broadband customers
-
To provide dial VPN service to MPLS VPN customers.
-
To provide multicast video services,
video-on-demand, etc. through the Broadband Remote Access Server (BRAS).
-
To provide a means to bill for the aforesaid
services by either time-based or volume-based billing. It shall provide the
customer with the option to select the services through web server
-
To provide both pre-paid and post paid broadband
services

 Technical
Capability of the Backbone |
| |
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 Gbps(STM-16) links. The routers are located on
the national DWDM network interfacing at STM-16 optical level to provide for
high transmission speeds. |

What
advantage does MPLS have over other Technologies? |
| |
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.
