Abstract

The paper presents rationale for the choice of the structure of data transmission and recording system (DTRS) and describes the software developed for this system based on processing high-speed data flow with netmap. Hardware used to build DTRS (such as server and disk array models, CPUs and NICs, etc.) is described in detail. The results are given of DTRS software performance during the 2016-2019 observations with the RT-13 radio telescopes at Badary, Zelenchukskaya and Svetloe observatories of the Quasar VLBI network.
