Abstract:
With approximately 250 million Internet users, India stands amongst the top 5 Internet using
nations of the world. India's network space is made up of 789 Autonomous Systems (ASes),
that route all the network traffic of India. On the other hand, US has approximately 300
million users, whose traffic is routed over 22K ASes. Thus, a relatively small network routes
the traffic of large number of Indian users. Failures and attacks in such networks could impact
large number of users. However, being a relatively small number, it becomes easy to generate
maps presenting the connectivity of ASes in the networks and the routers that make up the
ASes. Such information could be used for various purposes such as diagnosing network failures
and attacks, large scale network surveillance and bypassing such surveillance, load balancing,
efficient content distribution and delivery.
We present, a first effort to our knowledge, the topological information of India's entire Internet
space representing the connectivity between all 789 ASes and intra-domain routers. Our research
presents information of routers and ASes that transport relatively large fraction of tra c for vital
network installations like popular ISP users, important organizations like nancial institutions,
educational institutions, research organizations etc.
