Back in 2017, Google Cloud launched a low-performance tier and effectively gave an option to their customers of “cheaper” bandwidth with slightly reduced performance. This page describes their network tiers in detail. That page says - “Cost optimized: Traffic between the internet and VM instances in your VPC network is routed over the internet in general.” Background For a while, I wanted to find out how this works. In network routing this concept is known as “hot potato routing Vs cold potato routing”.
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.

One of frequent email and contact form message I get my blog is about available content networks in India and where one can peer. There are certain content networks in India and of course most of the content networks have open peering policy and are usually happy with direct inter-connection (we call as “peering”) with the ISP networks (often referred to as “eyeball networks”). Some of these networks have a backbone which connects back to their key datacenter locations on their own circuits via Singapore/Europe, some other have simply placed their caching server where cache fill happens over IP transit.
