Science DMZ Workshop

REANNZ and NeSI together bringing you the Science DMZ

We are sometimes faced with datasets too large to email. We resort to saving large datasets on hard drives to courier across the country, rather than sending them across the network. This is increasingly unnecessary, and is easily resolved. Institutions that adopt contemporary network configurations and data transfer services, are able to reap the benefits of high speed research networks to quickly transfer large datasets.

REANNZ and NeSI will demonstrate the effect of carefully configured data transfer services atop a well tuned research network at the eResearch Symposium VUW 4-6th July. You will see the differences that can easily be made to data transfer performance, and even learn how to optimise your institutes network connection for large data transfers. However this is only part of the picture – gain access to large data transfer tools and learn more about the data transfer services available, including programmable transfers, and easy to use tools available today researchers in NZ.

For those technically minded, the network approach we’re demonstrating is a prototype of a Science DMZ network architecture and uses a performance-testing tool, perfSONAR, to identify bottlenecks. Atop this, we’re working with GridFTP and GlobusOnline for data transfers. Come talk to the engineers involved from both REANNZ and NeSI to learn more.

If you are attending the Symposium please come along to our booth or workshop, we look forward to seeing you there.

If you are not able to get to Wellington for this, please contact us and we’ll be happy to talk with you.

eResearch Symposium preparation

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.

REANNZ International Connectivity

Ever wondered if you can reach your international collaborators over the REANNZ Network?

This map shows you where we reach…

Networks are the common infrastructure that binds communities. At REANNZ, we form part of the research, education and innovation ecosystem, connecting participants in those sectors to each other and the world. Nearly all developed countries, and many developing countries, have a research network similar to REANNZ.

More information about our international connectivity can be found here, along with tools to see if your specific collaborator is on the other end of our network connections.

Software Defined Networking – The Openflow Bootcamp

Victoria University of Wellington (VUW) and REANNZ recognised the growing national interest in Openflow and worked together to provide an opportunity to gain practical hands on Openflow experience in the form of a Bootcamp.

Attendance

The Openflow Bootcamp was the direct result of an earlier Openflow Workshop where attendees indicated they wanted to participate in a “doing” exercise.  Twenty seven people attended VUW on the 7 May and twenty three got their hands dirty, one of the workshop attendees even came over from Australia.

 

What they did

Josh Bailey of Google led the day and provided an overview of Openflow before taking attendees to the computer lab. The attendees worked in small groups to do everything from configure switches from scratch, to compile, install, troubleshoot and run RouteFlow, to configure Quagga from woe to go. The groups were able to make five openflow controlled switches (one Pronto and four HPs) come up in a full mesh. The first person to successfully bring up a RouteFlow controlled switch was VUW’s Mark Davies.

 

REANNZ’s Sam Russell gave a talk on pyswitch and explained in great detail the problems with the example code (broken for more than 2 switches by default, etc) and how he fixed it. His talk was at the end of the day and it was very clear the audience were very familiar with the topic and followed Sam’s explanation easily.

 

Contributors

Thank you very much to HP for providing the switches (which basically worked with RouteFlow out of the box) and to VUW’s Radek and Mark for setting up the lab.  Finally, thank you to those who attended on the day and made the bootcamp such a success. There is now even more interest in Openflow here in NZ………

Terena Networking Conference 2012

If the idea of attending a leading research and education network conference on the other side of the world appeals, then the TERENA Networking Conference (TNC) 2012 may be for you.

Overview

The TNC will take place from 21-24 May 2012, in Reykjavik, Iceland. Hosted by the Icelandic national research and education networking organisation, RHnet, and the University of Iceland, the conference will present an overview of the latest developments in research networking both in the technical field and in the areas of application and management.

According to the conference website, “The TNC is the largest and most prestigious European research networking conference. It typically attracts over 500 participants including decision makers, networking specialists and managers from all major European networking and research organisations, universities, worldwide sister institutions and industry representatives.

“This year’s theme is ‘Networking to Services’ and will focus on network technologies, infrastructures and services that support research and education.”

Registration is open

You can register for the TNC now, through the conference website.

That website also contains useful information on flights, accommodation, and the conference schedule—including a preliminary programme. And if you book before April 13, you’ll get a discount off the attendance fee.

The Internet and Advanced Networks workshop

This workshop is designed and run by Packet Clearing House from San Francisco and is lead by some of the world’s leading Internet and infrastructure specialists, it has been delivered scores of times, from Nepal to San Francisco and everywhere in between. This event will be held 21-25 June in Wellington at a cost of $150.

At the end of the workshop it is expected attendees will have a much greater understanding of Inter-networking and the technologies that build the Internet and how to deploy them.

The workshop will cover the following:

  • Internet infrastructure and how the net is put together, how transit providers connect, who pays who and the economics of connectivity
  • Peering, transit and network economics
  • Provisioning – How you build an network service and Inter-network, how the routers and their functions build the Internet and how you can do it
