The 3 ATNF telescopes are connected to Sydney via 1 Gbps “lightpaths”. This is shared with production traffic to the observatories.
What protocol needs to be used for the transfers? TCP, UDP, VSI-e, something else? If anything other than TCP (or a similar reliable stream interface) is used then is a packet header format needed (so lost packets don't screw up the data stream).
The Mark5B “file” format will be used. This consists of the raw baseband data with regular time headers and header CRC.
A thin Mark5(B?) client will be written which emulates a real Mark5 and directly controls the LBADR recorder.
