National Stock Exchange of India : Nationwide Network

National Stock Exchange of India provides a sophisticated online trading

platform for the trading community in India. It connects various traders across

India by utilizing an array of satellite technology and terrestrial leased line

network and to provide them with fairness and full transparency trading . As an

endeavor to further enhance the trading experience and to provide value added

services to the members, NSE embarked upon a project to deploy a robust and

secure private IP network. This IP network was implemented via a dual hub and

spoke topology with multiple providers and nine Points of Presence across India.

Out of these, three POPs are located in Mumbai, two each in Delhi and Kolkatta,

and one each in Ahmedabad and Chennai. The backbone connectivity of all POPs to

the NSE data centers is through a high availability, high bandwidth links from

multiple service providers.

The implementation of this network has enabled several new business

capabilities for NSE. It can now provide a richer Market Data broadcast that

will have an instant visibility of liquidity in the market.

NSE can now offer multiple connectivity scenarios to the highly resilient WAN

with varying degrees of throughput and automatic failover possibilities across

service providers, POPs and VSATs. Members can thus select connectivity from 5

different service providers (Bharti Airtel, BSNL, MTNL, Reliance and TATA) as

well as VSAT. This project on a whole is meant for benefiting the Trading

Fraternity by giving them an opportunity to build redundancy in their setup and

consolidate their IT infrastructure.
