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 of the South Asian countries such as India and Pakistan are making making progress in this direction by not only building Grid clusters, but they will have also by improving their network infrastructure. However to facilitate the use of these resources, they need to overcome the issues of internet/network facilities if they are to become a player in global Computing in network 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 these regionsSouth Asia. The quantitative measurements are carried out using the PingER methodology; a lightweight approach using 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 of NERNs and Grid infrastructure in state of the National Research and Educational Networks (NRENs) and Grid Infrastructure in the South Asian countries and point out what identify the problem areas are. We will areas of concern. We also present comparisons between South Asia and other developing as well as developed regions. We show that there is a strong correlation between the Network performance and various several Human Development Indicesindices.
