jive5ab — Overview

Description

jive5ab is a third-party VLBI recorder developed by JIVE (Joint Institute for VLBI ERIC). Within the DBBC plugin it is deployed as a persistent EDD service that receives VDIF frames from the VDIFPacker over UDP and writes them to disk. It implements the standard MK5 control protocol on port 2620, allowing the Field System to issue record commands directly.

The container is started automatically at provision time and restarts on failure so it is always available when an observation begins.

Responsibilities

• Receive UDP VDIF frames from the VDIFPacker (default port 4991)

• Write VDIF data to disk under the configured recording path

• Expose the MK5 control protocol on port 2620 for Field System integration
