Peering with content networks in India

peering

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.

 

Based on publically known information across community and of course peeringdb, following content players are available in India and known to be open for peering:

  1. Google
  2. Microsoft
  3. Amazon
  4. Limelight

 

A quick list of these with datacenter names and locations as taken from Peeringdb record of these networks.

Besides these Google also has an option of GGC, Akamai has an option of Akamai Caching server, Facebook has the option for caching server which is hosted inside ISP’s network and Netflix has an option for OCAs. Besides these networks there are known nodes of Verizon’s Edgecast in Delhi, Mumbai & Chennai (as per this map), Cloudflare has nodes in Delhi, Mumbai & Chennai (as per this map), PCH & K-root server have a node with Web Werks available on MCH peering fabric and Dyn has a node in Mumbai (as per this map).

Go ahead and peer as after all it all starts with a handshake. 🙂

Welcome to AWS Cloud Mumbai region

 

It’s great to see Amazon’s announcement two days back about launch of their region in Mumbai. In past I was quite happy to see their Cloudfront CDN PoPs in Mumbai & Chennai (blog post here). Now it’s just great to see a full AWS region out of Mumbai. 🙂

Though it’s going to eat most of important customers from the smaller players still it’s good for industry as industry is too big and we need more & more of such large Cloud players in India to bring more and more content hosting in India.

 

So how does Amazon’s Indian network is connected at the moment?

Let’s trigger a VM on Amazon EC2 in Mumbai and test based on routing of various networks to it’s IP and return.

 

On the instance:

 

Trace from Amazon to outside world:

 

So clearly Amazon is reaching all domestic destinations via Tata (AS4755). Let us  look at other side around i.e reaching from domestic destinations to Amazon by BGP table as well as trace from RIPE Atlas probes.

 

Routing table of NIXI route server:

 

So route for AWS Cloud in India seems via Tata (AS4755). A quick check on latency from RIPE Atlas Indian Probes:

 

 

Clearly latency does seems little high from certain probes. Running a trace from them:

 

One thing which is noticeable here is high latency from BSNL (AS9829) backbone.

BSNL to AWS Mumbai

 

 

Summary and misc thoughts:

  1. AWS India seems to have PoP/datacenters across Mumbai, Pune and Hyderabad (based on visible PTRs of their only Indian transit).
  2. AWS is using Tata (AS4755) in India to reachout to all Indian networks with highly likely option of peering with other Indian networks in near future.
  3. There seems to be a “pipe” connecting AWS Mumbai region with their Singapore network and I see most of their international traffic flow (traffic TO and FROM outside India over their own PoP and transits which they are using in Singapore).
  4. Connectivity seems OK from Tata Communications & Airtel while seems not very good with Reliance (AS18101) and BSNL (AS9829). BSNL is pushing some of the traffic out via AS6453 IPLCs outside India while Reliance is preferring FLAG (AS15412) > NTT (AS2914) > Amazon routes over (likely) visible routes from Tata (AS4755).

 

Time for me to hop on to next flight and get to home. 🙂
