More than 99% of the internet traffic relies on high quality fiber optic cables connecting various countries. Only a minuscule part of the traffic goes through satellites.
These cable networks are laid and maintained by various governments and giant companies. Such projects are usually undertaken by multiple companies due to the large cost of investment. There are three tiers which differentiates the size of the network held by a company.
Tier-1 :- This are the companies which have a global network connecting so much cables around the world that they don't need to pay anyone any fee to access any destination on the internet. They usually can access the network of other tier-1 companies without paying any fee. This network acts as the backbone of the internet.
Tier-2 :- These are companies which have a regional networks and are usually connected to one or more tier-1 networks. They have to pay a fee to access the tier-1 company's network.
Tier-3 :- These are the Internet Service Providers(ISPs) from whom we buy our broadband connections. They are the last tier, connecting the internet to the end users.
Relationship between the various tiers on Internet providers
This may come as a surprise, but more than 24% of the internet's traffic goes through TATA's cables! TATA communications is one among the few global tier-1 Internet service providers in the world. Tier-1 means that they have enough cables to connect the world that they don't need to pay anyone any fee to access any destination on internet! They are the only tier-1 ISP from India and the owner and operator of the world's largest fibre network, 240000 km. long.
TATA provides internet to the tier-2 companies which sells internet to normal tier-3 internet service providers from whom we buy our broad band connections. Companies like BSNL, MTNL etc buy bandwidth from Tata.
They wholly own the low latency fiber optic cable which connects eight of the word's most important trading platforms : London, Paris, New York, Chicago, Tokyo, Hong Kong, Singapore, and Mumbai. This is the first time such a global network is being build exclusively for trading. It is the orange cable in the map below. You can see that it is laid in a snake like pattern over Russia. This is to increase the redundancy of the network, if one cable gets damaged at some point, then the network can still remain live through the other cable.
They have build a network of more than 500,000 KMs of submarine fibre optic cables and 210,000 KMs of terrestrial cables reaching more than 240 countries. Just for a reference, circumference of the equator of Earth is 40,075KM.
One out of every 10 international voice calls goes through their cables. 70% of the mobile carriers in the world are connected to their network.
Even today, less than 1% traffic(voice, internet, everything) goes through satellites, the remaining 99% still relies on the cable system. The internet which you use in your phone connects to the cell tower and then the cell tower is typically connected to an ISP through fiber optic cable under the tower.
Their cables in India
They have cable landing stations in Mumbai, Kochi and Chennai. These are the places at which the international underwater cables reaches India. These are high quality fiber optic cables capable of over 1TB per second.
Tata communications have so much bandwidth in their Indian landing stations that they have not even turned on some of their cables connecting India. Only about 60% of the cables are in use, the remaining cables are called 'dark fiber'. It is planned to be turned on in the future when demand for internet speed/bandwidth increases!
Their cable crosses Pakistan's land borders to reach Jammu.
Internet costs are generally higher in northern parts of India because they are far away from international landing stations. The latency while accessing international sites is also higher in northern parts of India due to the same reason. (high latency in simple words means slower response time in internet)
Large ships specifically build for this purpose are used to lay the underwater cables. It is usually accompanied by an underwater rover which places the cable on the seabed. It can take years and 1000s of crores worth of investment to complete an international network. Such projects are usually undertaken together by multiple companies and governments.
Tata communications was originally started as VSNL by government of India and was acquired by Tata in 2002- a time when internet and telecommunication was starting to grow in India. They further acquired a Canadian network company Teleglobe in 2005 for $238 Million dollars.
Since, currently most web-servers are located outside the physical boundaries of India, large international bandwidth is used by us to use internet. We should make an effort to make India an ideal location for companies to start their data centers. Currently, all major companies interested in south Asian market are establishing their data centers in Singapore.
Few years ago, the most valuable building of a city was the bank, but now the most valuable buildings are the data centers.
From the tiny electromagnetic coil of the first telephone in 1876 to the fibre-optic network that circles the globe today, technology has not only revolutionized the way we communicate – it has transformed our world and the way we live. The Internet, some say, is ubiquitous. Some call it a digital age. We call it the New World of Communications™.
Through our global network, the world’s largest, we’re proud to play a major role in the emergence of this new world. The Tata Communications Global Network reaches more than 240 countries and territories, 99.7% of the world’s GDP, millions of businesses, and billions of people. And it includes:
• One of the largest, most advanced subsea cable networks, 500,000 kilometres long
• A terrestrial fibre network stretching 210,000 kilometres
• A global Tier-1 IP network with more connections into more countries than any other carrier
• The world’s only fibre ring around the world
• The only Ethernet ring in the Middle East
• More than 1 million square feet of data centre space in 44 locations worldwide
Our network carries a huge volume of the world’s voice and internet traffic.
In voice, we are the world’s largest wholesale carrier. Our network handles 1 out of every 10 international calls and connects more than 70% of the world’s mobile carriers. On the Internet, we’re a major Tier-1 IP provider, consistently ranked in the top five telecommunications companies on five continents, by internet route. In fact, we handle more than 24% of the global internet traffic, totalling more than 7,300 petabytes a month.
