摘要

The present invention relates to a stable transmission system of a large-capacity VLBI data stream using a TCP/IP-based ring buffer, and a digital backend that converts, generates, and outputs a radio wave signal coming through a receiver into a UDP frame by observing each telescope's telescope. ; A VLBI observation data stream in the form of a UDP frame is first stored in a large-capacity ring buffer via a receive socket buffer in the observation hall, and then transmitted through a transmit socket buffer as a variable number of TCP packet streams according to network performance degradation. A first Linux server system; A second Linux server system for receiving a TCP packet transmitted to a correlation center in a single or parallel stream over a long distance high-speed network through a receive socket buffer and copying it to the ring buffer when it is verified that no abnormality has occurred; And storage for sequentially storing TCP packets stored in the ring buffer of the second Linux server system in incremental increments of read/write pointers.
