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 traffic for vital
network installations like popular ISP users, important organizations like financial institutions, educational institutions, research organizations etc.
