A Scientific Overview of Network Connectivity and Grid Infrastructure in South Asian Countries
The future of Computing in High Energy Physics (HEP) applications depends on both on the Network and Grid Infrastructureinfrastructure. Some Some South Asian countries such as India and Pakistan are making making progress in this direction for example by not only building grid clusters. To Grid clusters, but also by improving their network infrastructure. However to facilitate the use of these resources, they will have need to overcome the issues of internet/ network facilities to become a player in global Computing in connectivity to be among the leading participants in Computing for HEP experiments. In this paper we aim to classify the connectivity for academic and research institutions of South Asia. The quantitative measurements are carried out using the PingER methodology; a lightweight approach using the ICMP ping facilityan approach that induces minimal ICMP traffic to gather end-to-end network statistics. The PingER project has been measuring the Internet Performance performance for the last decade. It now covers Currently the measurement infrastructure comprises of over 700 hosts in over more than 130 countries that contains over which collectively represents approximately 99% of the world's Internet-connected population, so it is . Thus, we are well positioned to characterize the world's connectivity. We will Here we present the current state state of the National Resarch Research and Educational Networks (NRENs) and Grid infrastructure Grid Infrastructure in the South Asian countries and point out identify the problem areas of concern. We provide also present comparisons between South Asia and other world developing as well as developed regions. We will also show that there is a strong correlation between the Network performance and various several Human Development indices.
