2. Basic Internet Structure3. NBPo National/International Backbone (Internet/Communication)Providero National-ISPo VSNL

4. VSNLo Videsh Sanchar Nigam Limited, now Tata Communication Limited.

(http://www.tatacommunications.com/)o 1986, VSNL created.o ISPAI (http://www.ispai.in)o Category (a) & (b)o Every category have their own 10 policieso NIXI (http://nixi.in)

5. ISPs in Indiao BSNL,o Airtel,o Sify,o HFCL,o Reliance Communications,o Tata Teleservices,o Spice,o MTNL,o You-telecom, etc.

6. FIXo Federal Internet Exchange.o Physical location where servers get connected.o US has 2 FIXes FIX-E(MaryLand) & FIX-W (NASA Ames Research Center, California)7.o VSNL / TATA Communications is Tier 1 Bandwidth provider.o VSNL have principal ownership status in SMW-3, SMW-4, SAFE, TIC (100% owned)

and capacity ownership in FLAG and I2I.o world’s largest providers of submarine cable bandwidth.

8. International connectivityIndia at Mumbai.455 Mbps direct connectivity to the Global Center in New York, through a 40 Gbps Global optical fiber system.500 Mbps of fiber capacity and 450 Mbps of satellite capacity to the Indian network

9. VSNL Recently bought 2 big telecommunication companies: Tyco Global Network & Teleglobe Holdings. Network comprising of over 200 ISPs, 400 nodes and over 3000 corporate leased lines and the National Internet Backbone (NIB) of BSNL.fabric is linked to Mumbai-VSB with high speed Internet nodes located at Cochin, New Delhi, Chennai, Calcutta, Bangalore, Hyderabad and Pune which forms 90% of the Internet usage in India.

10. Internet Exchange Pointo An Internet exchange point (IX or IXP) is a physical infrastructure through which

Internet service providers (ISPs) exchange Internet traffic between their networks.o A typical IXP consists of one or more network switches, to which each of the

participating ISPs connect. o The primary purpose of an IXP is to allow networks to interconnect directly, via the

exchange, rather than through one or more 3rd party networks.11.o The advantages of the direct interconnection are numerous, but the primary reasons

are cost, latency, and bandwidth. Traffic passing through an exchange is typically not billed by any party, whereas traffic to an ISP's upstream provider is.

o In many cases, an ISP will both have a direct link to another ISP and accept a route (normally ignored) to the other ISP through the IXP; if the direct link fails, traffic will then start flowing over the IXP. In this way, the IXP acts as a backup link.

12. National Internet Exchange of India o NIXI is a non-profit Company established in 2003 to provide neutral Internet Exchange

Point services in the country.o It was established with the Internet Service Providers Association of India (ISPAI) to

become the operational meeting point of Internet service providers (ISPs) in India.o Its main purpose is to facilitate exchange of domestic Internet traffic between the

peering ISP members, rather than using servers in the US or elsewhere. This enables more efficient use of international bandwidth, saving foreign exchange. It also improves the Quality of Services for the customers of member ISPs, by avoiding multiple international hops and thus reducing latency.

13. NIXI currently has seven operational nodes at the centers in Delhi (Noida), Mumbai (Vashi), Chennai, Kolkata, Bangalore, Hyderabad and Ahmedabad.ISP Members in Delhi (Noida)Bharat Sanchar Nigam Ltd BhartiAirtel Ltd Dishnet Wireless limited ERNET India Hathway Cables & Datacom Ltd.
