Abstract

The article presents the results of the long-term buffering operation and data transfer systems serving the needs at the Svetloye, Zelenchukaya, Badary, and Ussuri Astrophysical Observatories, the Correlation Processing Centre, the Data Processing and Analysis Centre, and the Centre for Collective Use at the Institute of Applied Astronomy of the Russian Academy of Sciences during 2012–2022. The main difficulties in maintaining a complex geographically distributed information system are listed. These most significant problems include failure of hard disk drives and UPS batteries after the expiration of the guarantee period. Further paths for the development of the systems used are proposed. The data transfer volumes of radio interferometric observations using the radio telescopes RT-32 and RT-13 of the VLBI complex “Quazar-KVO” are given. It is noted that to ensure the prompt delivery of observational data to processing centers, the availability of communication channels with sufficient bandwidth is essential. The National Research Communication Channel can be used as such a communication channel. There are given the results of testing this channel and comparison with the communication channel currently used. It is noticed that the e-VLBI technology implemented at the “Quazar-KVO” complex allowed to provide high efficiency in determining UT in the interests of fundamental and applied research in near and deep Space, in particular, to ensure the GLONASS space navigation system. The article lists the most critical and frequently failing systems and gives recommendations on what to pay attention to when monitoring a geographically distributed information system. This is a review article describing the main operational problems and tools that help to control the increasing complexity of maintaining an information system of buffering and data transfer.

AB  - The article presents the results of the long-term buffering operation
and data transfer systems serving the needs at the Svetloye,
Zelenchukaya, Badary, and Ussuri Astrophysical Observatories, the
Correlation Processing Centre, the Data Processing and Analysis
Centre, and the Centre for Collective Use at the Institute of Applied
Astronomy of the Russian Academy of Sciences during 2012–2022. The
main difficulties in maintaining a complex geographically distributed
information system are listed. These most significant problems
include failure of hard disk drives and UPS batteries after the
expiration of the guarantee period.   Further paths for the
development of the systems used are proposed. The data transfer
volumes of radio interferometric observations using the radio
telescopes RT-32 and RT-13 of the VLBI complex “Quazar-KVO” are
given. It is noted that to ensure the prompt delivery of
observational data to processing centers, the availability of
communication channels with sufficient bandwidth is essential. The
National Research Communication Channel can be used as such a
communication channel. There are given the results of testing this
channel and comparison with the communication channel currently used.
It is noticed that the e-VLBI technology implemented at the “Quazar-
KVO” complex allowed to provide high efficiency in determining UT in
the interests of fundamental and applied research in near and deep
Space, in particular, to ensure the GLONASS space navigation system.
The article lists the most critical and frequently failing systems
and gives recommendations on what to pay attention to when monitoring
a geographically distributed information system. This is a review
article describing the main operational problems and tools that help
to control the increasing complexity of maintaining an information
system of buffering and data transfer.
