How technology loses out in companies...

Anurag Bhatia
Just came across this brilliant talk by my friend Bert Hubert. It covers so nicely about the mad rush to just outsource everything and how innovation is lost. While he mentioned names of EU telcos in examples, unfortunately situation isn’t that different in this side of world either. Operator in South Asia also very much suffer with this problem. Slides of this presentation are here.

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).

Using BGP communities to influence routing

Anurag Bhatia
Some free time here in Europe and thus time for another quick blog post & to take my mind away from depressing people! One of impressive features of major European networks is support for BGP communities. In India it’s almost non-existent. Setting it up isn’t hard technically but from capacity management side, Indian ISPs are somewhat shy in setting it up. Let’s put a case where we have a Customer router (R1 with AS1), upstream of customer (R2 with AS2), upstream of upstream (R3 with AS3), peer of upstream (R4 with router4).
