Peering

OTT and paid peering

Yesterday there was an article in the Indian paper Financial Express with the title “OTTs may have to pay access charge to telcos”.

Quoting a few points from the article:

  • Social media intermediaries like WhatsApp, Facebook and Twitter, and over-the-top (OTT) players like Netflix, Prime Video and Disney+Hotstar may have to pay a carriage charge to telecom service providers
  • Data, particularly video, comprises 70% of the overall traffic flow on telecom networks, and this would grow further with the rollout of 5G services
  • Upon reference from the DoT, Trai is currently studying various possible models under which OTTs can be brought within the purview of some form of regulation
  • According to sources, an interconnect regime is a must between OTTs and telcos because as 5G services grow, there would be immense data/ video load on networks, which may lead to them getting clogged or even crashing at times.

This concept of “OTTs must pay” is not new. This has been argued a few times in past. Exactly ten years ago in 2012 I wrote a blog post about Bharti Airtel expecting Google/YouTube to pay. At that time they could not convince OTTs to pay. Why is this renewed interest now? Well, that has to do with the first SK Telecom (South Kore telecom) Vs Netflix court case in South Korea where SK Telecom claimed that a large part of bandwidth utilization was because of Netflix and hence they should pay a “fair share” of their traffic which they lost. Soon around this multiple of large telecom monopolies in Europe started this discussion in their respective geography. Four of the top EU players - Deutsche Telekom, Orange, Vodafone and Telefonica are of opinion that OTTs should share the burden (news here). And hence Indian telcos possibly looking to renew this debate.

Algorithm to detect a transit free network

In a recent Network AF podcast Avi Freedman (Kentik) joked with the guest about how he finds who is transit free / tier 1 network. He said, “I ask everyone who they think is a tier 1 network. Everyone includes their own name + other names”. Next, he ignores the self-nomination & looks at the common list to find who actually is a tier 1 network. This is funny, intuitive and gives some clue.

Inefficient IGP can make eBGP go wild!

Lately, I have been struggling to keep latency in check between my servers in India and Europe. Since Nov 2021 multiple submarine cables are down impacting significant capacity between Europe & India. The impact was largely on Airtel earlier but also happened on Tata Comm for a short duration. As of now Airtel is still routing traffic from Europe > India towards downstream networks via the Pacific route via EU > US East > US West > Singapore path. Anyways, this blog post is not about the submarine cable issue.

NIXI expansion & some thoughts

Background

Lately, NIXI has been making a bit of news in the Indian peering ecosystem. NIXI for those who may not be aware is the National Internet Exchange of India. It was founded in 2003 with the idea to provide inter-connection layer 2 peering fabric for local Indian ISPs. They were supposed to ensure domestic Indian traffic is exchanged within India and not outside of India. In my previous post, I did cover how that is not true for now. They never picked up much interconnection due to a number of fundamental issues with their policies.

Why Indian internet traffic routes from outside of India?

After my last post about home networking, I am jumping back into global routing. More specifically how Indian traffic is hitting the globe when it does not need to. This is an old discussion across senior management folks in telcos, policymakers, and more. It’s about “Does Indian internet traffic routes from outside of India?” and if the answer is yes then “Why?” and “How much?”

It became a hot topic, especially after the Snowden leaks. There was even an advisory back in 2018 from Deputy National Security Advisor to ensure Indian internet traffic stays local (news here). Over time this has come up a few dozen times in my discussion with senior members from the Indian ISP community, individuals, and even latency-sensitive gamers. So I am going to document some of that part here. I am going to put whatever can be verified publically and going to avoid putting any private discussions I had with friends in these respective networks. The data specially traceroutes will have measurement IDs from RIPE Atlas so they can be independently verified by other network engineers.
