标题： Radio Astronomy and eVLBI using KAREN

摘要： Kiwi先进研究和教育网络（KAREN）已被用于在新西兰瓦卡托鲁的AUT射电天文台与我们合作并进行观测的国际组织之间传输大量射电天文数据。在此，我们报告了当前的连接状态以及测试不同数据传输协议的结果。我们调查了新的UDP协议，如“tsunami”和UDT，并证明UDT协议比“tsunami”和ftp更高效。我们报告了实现实时eVLBI的初步步骤以及尝试直接从射电望远镜接收系统向相关中心流传输数据而无需中间缓冲/记录的尝试。 显示英文摘要

摘要： Kiwi Advanced Research and Education Network (KAREN) has been used to transfer large volumes of radio astronomical data between the AUT Radio Astronomical Observatory at Warkworth, New Zealand and the international organisations with which we are collaborating and conducting observations. Here we report on the current status of connectivity and on the results of testing different data transfer protocols. We investigate new UDP protocols such as "tsunami" and UDT and demonstrate that the UDT protocol is more efficient than "tsunami" and ftp. We report on our initial steps towards real-time eVLBI and the attempt to directly stream data from the radio telescope receiving system to the correlation centre without intermediate buffering/recording.
