New 10Gb/s Link Enhances REANNZ Network Resiliency
One of our key goals is to provide a network platform that supports production quality advanced services, networking research & development and experimental test beds. The impact of REANNZ delivering this, will mean that our users are able to conduct research, education and innovation that could not occur without the reach, reliability and speed of an advanced network.
We are constantly seeking ways to augment and enhance the REANNZ Network so that we are able to deliver this essential networking infrastructure for our community. From the outset of the network, we have been aware of the vulnerability of the single path between the North and South Island, and have now been able to secure a second, alternate path between them. Currently, we are commissioning a 10Gb/s circuit from Avalon (AVL) to Christchurch (CHC) that will improve the network resiliency by avoiding the bottle neck of the Cook Strait. The circuit will be provisioned on the TelstraClear AquaFOTs fibre as a 10Gb/s wavelength service.
The map below shows the enhanced REANNZ Network.
Our weathermap will be updated when the circuit goes live.

The 3rd New Zealand eResearch Symposium will be held at Victoria University of Wellington, on Wednesday 4th – Friday 6th July, 2012.
In preparation for the Symposium, REANNZ and the University of Auckland are performing tuning activities over the REANNZ international link to Los Angeles (LAX) that will enable large file transfers using gridFTP. Testing will occur over the Los Angeles (LAX) link on Thursday 21st and Monday 25th June from 9:00am. You can watch the progress on the REANNZ Weathermap here.
If you are attending the Symposium come to our workshop to see live large file transfer demonstrations and learn what needs to be done to achieve them. The workshop is on 11-12:15pm Friday 6th July. You can also visit us at our booth.
Australasia’s first ever virtual e-telescope will come to life today, when six Australian and New Zealand radio telescopes link together in real time.
First ever Trans-Tasman Virtual e-Telescope
Researchers from AUT University’s Institute for Radio Astronomy and Space Research (IRASR), Australia’s CSIRO (Commonwealth Scientific and Industrial Research Organisation), the University of Tasmania and Curtin University will use a technique known as Very Long Baseline Interferometry (eVLBI) to collect huge amounts of data simultaneously from five radio telescopes observing a very remote quasar.
All the radio telescopes will be operated remotely from AUT’s Warkworth Observatory. Data will be streamed from the telescopes to the Narrabri, NSW processing centre via KAREN and its Australian counterpart AARNet, processed in real time, and the results will be immediately seen on a big screen in Warkworth.
“This demonstration is an important step in the Australasian SKA (Square Kilometre Array) bid, which will be based on exactly the same eVLBI technique,” says Gulyaev. “We are excited to try out this technology and show what is possible when Australia and New Zealand radio astronomers join forces.”
KAREN in action
In the spirit of the draft KAREN Resource Allocation policy, Dr. Sergei Gulyaev of AUT has scheduled this experiment off peak hours of network usage. REANNZ encourages all members of the community to comment on and be familiar with community policies found on the KAREN wiki.
The image below from the KAREN Weathermap shows pre-experiment testing over KAREN taking place earlier today. You can also see the KAREN Weathermap in real time.
