Abstract

Currently, the IAA RAS develops buffering system and data transmission for observations with radio telescopes of small diameter (13 m), which are also intended to realize the goals of the international program VLBI-2010. Main system goals: — recording of 8 data streams (with scalability up to 16) in the VDIF format with data speed 2 Gbps from each channel; — realizing data transfer to the Data Processing Center at 10 Gbps transfer speed simultaneously with recording and buffering data; — storing observations data up to 20 TB size in generic file structure with set of disk pools.
