Peering with content networks in India

Anurag Bhatia
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.

K root server - Noida anycast and updates

K root in Noida seems to be not getting enough traffic from quite sometime and connectivity does seems bit broken. This is a blog post following up to Dyn’s excellent and detailed post about how TIC leaked the world famous 193.0.14.0/24 address space used by AS25152. It was good to read this post from RIPE NCC written by my friend Emile (and thanks to him for crediting me to signal about traffic hitting outside!

Good bye BSNL (AS9829) | New link at home!

Anurag Bhatia
A blog post dedicated to BSNL AS9829. It just tried so hard to become as irrelevant as it can from everyone’s life (and that doesn’t excludes me now). So what really is BSNL btw? A Govt of India telco sitting at a extensive fiber of over 600,000 Kms across the country (staying just unused and unavailable for anyone’s use!) A telco which has an extensive last mile copper (which is very poorly maintained and barely works!

Airtel 3G running CGNAT

Yesterday I was driving and radio was pretty boring. Next, I connected cell phone to car’s stereo (I use a PT-750 to wirelessly connected my devices to car’s audio system). Next I tuned into Gaana.com app and experience was overall good. The way whole setup was working itself is a wonder - wireless profiles keeping layer 3 link (IP address of device) consistent and handovers happening on layer 1. On top of that a while world of backbone routing across AS9498 backbone the hosting provider’s network of the app.

Understanding the game of bandwidth pricing

Anurag Bhatia
I thought about this long back - “Who pays to whom in case of internet bandwidth?” I have been working in this domain from sometime and so far I have learnt that it’s really complex. I will try to put a series of blog post to give some thoughts on this subject. Firstly we have to understand that when we talk about “bandwidth price” it’s often layer 3 bandwidth which you buy in form of capacity over ethernet GigE, Ten-GigE and so on (or STMs if you are in India).
