Colorado State University (CSU) operates a radar at Greeley, Colorado. The CSU-VCHILL (Virtual-CHILL) project is aimed at developing and implementing protocols for providing the raw radar data to researchers in real-time over the internet. The Next Generation Internet has features, which could be used to transfer raw time-series data generated by the radar. In this project we have developed a network transfer application with TCP as the underlying protocol. This network transfer application has been successfully tested to provide throughput of 90 Mbps over a 100 Mbps link and 300 Mbps over gigabit link. We have also implemented a software digital signal-processing module. A network transfer application with User Datagram protocol as the underlying protocol was also developed. The performance of the software digital signal processing unit and the TCP version of the application to transfer the data across the network meet the requirements in most areas.
