A large part of the networks connected to DE-CIX consists of small ISPs, as these Internet exchanges enable them to save costs.
Internet exchange provider DE-CIX said its Mumbai facility has more peers than any Internet exchange point (IXP) in the Asia-Pacific region. “DE-CIX Mumbai currently has more than 359 networks peering on the exchange, placing it 1 out of 153 IXs tracked in 29 countries in the APAC region,” the company said in a press release and referred to a PeeringDB ranking page.
Internet exchanges provide Internet service providers and content providers with a means of exchanging traffic without using telecom operators that form the backbone of Internet networks, resulting in cost savings for many content providers and ISPs. Small ISPs benefit much more as they get access to popular content providers like Facebook, YouTube, Netflix, etc. without having to pay telecom providers for bandwidth.
Why is DE-CIX connected to so many networks?
This question is worth asking, as India is nowhere near the best-connected country in the Asia-Pacific region. Countries like Singapore and Malaysia clearly outperform India when it comes to internet connectivity. However, there are several factors that have led to this result: First, Internet switches are popular with landline Internet service providers to save costs; and cost savings are important as there are many more players in the fixed line broadband market than cellular operators. 82.1% of the 420 networks for now connected to the DE-CIX network appear to be small ISPs. 39 are content delivery networks like Amazon Web Services, Google, Fastly and Akamai; only ten are the hosting providers Sify and WebWerks. The rest is a small number of streaming services, IT enterprise service companies, and social media networks.
There aren’t that many providers in mature telecommunications markets – the farther a market is in terms of connectivity, the farther Less Internet provider has. Additionally, India is just one big country, and while universal connectivity is far from being achieved, the growth of wired broadband across the country means that more and more small providers are tapping into the stock exchange ecosystem. The same PeeringDB ranking page that puts DE-CIX at the top in terms of number of peers also has at least six exchanges in the top 20, which have fewer peers but have a higher capacity than DE-CIX Mumbai. Of course, exchanges in APAC route traffic worldwide, not just in the country where that exchange is located. India is currently more consumption intensive, which means that much of the data is likely to be consumed in the country itself.
