Today I met a good friend and he has recently moved back into Rohtak (like me!) and was crying over BSNL’s issues. He has issues of unstable DSL due to last mile and I told him that even if last mile works well, BSNL still has got ton of issues with their IP backbone traffic. It’s Sunday late night out here in India and I am having really pathetic connectivity with just everywhere except Google.
And my post on 1st April. Don’t take it as April fool post ;)
Multiple times NIXI’s AS24029 has been reported as acting like transit ASN for multiple networks. I have analysed it in past and this is very much because of route leaks by few specific networks. I have explained difference in peering Vs transit routes and their handling previously on my blog.
In short: A network is supposed to re-announce it’s peering and transit routes only to customer and not to any other peer or upstream.
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).
Earlier this month Dyn started with it’s Indian PoP. I came across news from Dyn’s blog post. It’s very good to see first Amazon AWS and now Dyn in India. With a warm welcome to Dyn let’s look at their Indian deployment.
Dyn using AS33517 which seems to be having upstream from Tata-VSNL AS4755 and Airtel AS9498. Dyn seems to be announcing 103.11.203.0/24 to both networks in Mumbai to transit. There are routes in global IPv4 routing table which show Tata & Airtel as transit for Dyn.
Today I spotted some routes from Amazon AWS Cloud services - AS16509 in Indian tables. AS16509 was originating prefixes while sitting in downstream of Tata-VSNL AS4755 and Reliance AS18101. I almost missed Amazon AWS's announcement on their blog about Indian PoPs for their DNS service - Route53 and CDN service - Cloudfront.
New PoP’s of Amazon in India are at Mumbai and Chennai and I see pretty much consistent BGP announcements to Tata and Reliance from these locations.
