The  “virtual world team” at the University of Auckland will be “productionising” its  Opensim installation – Hypergrid address: akl.nzvwg.org.8002.aotearoa – over the  the next couple of weeks which should see the university’s portal on the New Zealand Virtual World Grid ready to accept more tertiary institutions.

Announcing the move,  Dr Scott Diener (SL: Professor Noarlunga),  the Associate Director, IT Services,  at the University of Auckland, said the university  would now have separate servers for Development, Test and Production.

“The system will have four grunty production servers, which should host 30-50 sims, along with a separate database server for it all,” Dr Diener said. This  would add further stability to the user experience on the opensource OpenSim Version 7, HG 1.5 portal, he added/

The Auckland Portal now has voice working with Freeswitch, but the team is investigating licenses for Vivox as well. It also is investigating the use of the Havok physics engine which when and if implemented should further enhance the NZVWGrid experience, making  it near if not eqaul to the Second Life experience.

Dr Diener said  it  planned to subdivide  sims and “sell for $0 of course” the parcels to individuals  on the Auckland portal, which already includes Auckland University  and Nelson-Marlborough Institute of Technology sites as well as a SLENZ site  which will include the SLENZ Project builds from Second Life. There are also plans for a Virtual Life Education New Zealand  entry point.

The gateway point for Auckland Portal will become the Aotearoa sim which  also includes a Hypergate point to the hundreds of virtual world OpenSim  grids already mounted around the world.

Dr Diener has written a gaming system that includes a battle meter and weapons scripts that works well  in Second Life (0n sale at Academe), and appears to work  in the Opensim environment “….not great…but okay,” he said.

“I will be refining that as well, and intend to use it with some of the projects I laid out last year (eg involvement in the Life Games Project), he said, adding he was seeking other interested participants for this project.

Meanwhile the SLENZ project developer and wellknown Second Life builder, Aaron Griffiths (SL: Isa Goodman) has been given a commission to build some facilities for the University of Otago on the Otago portal (www. nzvwg.org) and he has also secured design work with the Manukau Institute of Technology, an orginal participant in the SLENZ Project, which is still determining whether to go with  Second Life, JokadyiaGrid or  the NZVWGrid for its current year foundation education work.

NZVWG – VLENZ Update, No 172, June 03, 2010

Does the Emperor have any clothes?

New Zealand’s NZVWGrid  ‘newbies’ get

free avatar skins, hair, eyes and clothing

A ‘noobie’ appearance is no longer necessary in the  NZVWGrid …
free avatarskins, eyes and hair have been made available for users  …

New Zealand academics, researchers and  virtual world builders,  using and testing the alpha phase of the New Zealand Virtual Grid (NZVWG), no longer have to look like ‘noobs’ even though given some of the vagaries of the OpenSim environment they might sometimes feel like that.

Open source  avatar skins,  eyes, hair and clothing  have  now been made freely available on the Auckland  portal of  NZVWG at Kapua 6  (NZVWG  Kapua 6/88/116/34), and are  likely to be made  available  near the Auckland entry point to the MUVE on Kapua 3  as well as at other Portal entry points.

The full permissions skins have been created by the likes of Eloh Eliot,  Ziah Li,  Greybeard Thinker and others, with  the clothing obtained  from a variety of sources outside  the Second Life environment, such as free, full permission listings of clothing textures.

All are being made available under   “Attribution-Share Alike 3.0 Unported” Creative Commons licenses.

The  NZVWG Project which grew out of  Otago University’s ONGENS programme is a joint venture of the University of Auckland,  the University of  Otago the University of Canterbury and  the Wellington Institute of Technology, Weltech.  A number of other institutions both in New Zealand and oversea have expressed interest in the project which is supported by New Zealand Telecom.

It is an open access national virtual world grid based on open source software. It operates on NZ-based servers hosted at Otago, Auckland and Canterbury Universities, and leverages other national investments in IT infrastructure through deployment on the high-speed KAREN (Kiwi Advanced Research and Education Network).

The grid has been set up with an academic focus and will be used for research and education, as well as for proof-of-concept application deployments and testing.

The project, based on opensource OpenSim  technology, is being led by one of New Zealand’s foremost virtual world education   champions, Dr Scott Diener,  an academic and  Associate Director, AC Tech, Information Technology Services,  at the  University of Auckland. Diener is well-known, both  as himself and as his Second Life personna, Professor Noarlunga, in MUVE  education circles around the world for his development of medical simulations and teaching programmes within Second Life.

Although little educational research is currently being done  in the alpha test phase of  the NZVWGrid there are opportunities once testing is completed. Besides  Diener’s Second Life University of Auckland virtual medical centre project in Second Life, which  may migrate to the NZVWG,  Otago University  has set up  the Otago Virtual Hospital in NZVWG (OtagoMedicalSchool/162/99/2800)  and is also hosting scenarios for medical students to gain experience practicing as doctors.   Some members of the now completed SLENZ Project are also active in the NZVWG although  there are no plans at this stage for a sequel to that successful research project.

KAREN goes  ‘independent’

NZ high-speed research/education

network in new partnership …

All NZ education to get real Broadband speeds

A year-old YouTube view of the FX Networks network  …
2200 kms of optical fibre and still counting.

Heralding a new era for online education and research  in New Zealand, Research and Education Advanced Network New Zealand Ltd (REANNZ) has announced  that it has  entered into a long-term partnership with the country’s foremost, independent optical fibre network provider,   Wellington-based  FX Networks,   to provide the national connectivity for the Kiwi Advanced Research and Education Network (KAREN).

The arrangement secures the continuation of KAREN’s existing 10Gb/s backbone connectivity and footprint around the country for an initial term of  three years through to December 2013, with two two-year renewal options.

The move should mean lower cost, and faster and more reliable  national bandwidth options for New Zealand tertiary and secondary education institutions, and could lead to a proliferation of virtual world and other third generation uses of the internet by  both faculty and students in education across the country. When coupled with other moves, it  should also provide benefits to distance learners.

Donald Clark, REANNZ

The Universities of Auckland, Otago and Canterbury, along with Weltech, in Wellington, are already operating a bandwidth-hungry,  OpenSim-based virtual world system (New Zealand Virtual World Grid) in test phase in conjunction with the KAREN network  which can only benefit from the latest development, which should ease both access and costs, especially  as NZVWG only uses local bandwidth, rather than international connections.

The decision to go with FX Networks  follows  what spokespeople for the two partners described as “a thorough and comprehensive evaluation process.”  The KAREN network has previously worked directly with  Telecom.

The contract also includes options to move KAREN to a dark fibre-based network infrastructure, which will be essential to ensure KAREN can continue to offer leading-edge network services within a constrained cost base.

The CEO of REANNZ, Donald Clark,  said, “This is the most exciting development for KAREN since the network was launched in 2006. We are confident that we have selected a progressive, long-term partner in FX Networks and have secured the best national connectivity options for our community and provided certainty to our members on cost and presence.”

“Over the last four years, the demands of our members has driven innovation in network supply and services across the telecommunications industry,” he said. “In earlier times our investments have helped other network suppliers extend their networks, now we’re helping FX Networks.”

Through moving to the new network, REANNZ will put into effect a new Network Access Policy which  will provide greater flexibility to REANNZ and KAREN members around access, and use of the network. The network is currently recruiting a number of secondary  schools to add to its current tertiary institution base.

A virtual region on the Weltech portal of the 'alpha' test NZVWG Grid .... online and MUVE education can only benefit from the latest KAREN move.

Work has already begun on comprehensive transition plan to ensure a smooth cross-over from current national connectivity arrangements to the new arrangements in December.

REANNZ is currently in the  late stage contract discussions with the preferred supplier for KAREN’s international network. An announcement on the selected provider will be made later this month.

FX Networks already has completed most of an optical spine the length of the country and is completing   a network right around the country to join with the spine – a number of  local bodies like those  controlling Hawkes Bay, Pahiatua, Dannevirke and Eketahuna among others   have already signed up with FX Networks –  which should make access to  KAREN  and true high-speed broadband internet an affordable reality for most  institutions as well as distance education students.

Jamie Baddeley, FX Networks

Previously, despite claims to the contrary, the major Telcos in New Zealand  have supplied  provincial New Zealanders  with Broadband, which they pay Broadband prices for, but which  generally  have not delivered consistent Broadband speeds. In fact,  in areas like the Manawatu, consumers, although paying Broadband prices, have often been left with a service, during  times of high contention, which   has run at dial-up speeds.

FX Networks’ fibre optic ‘backbone’ network  covering both islands of New Zealand, however,  is the fastest independent intercity pipeline in the country, capable of transferring data and voice at speeds up to 10Gbps.

The organisation describes its   network as a  ” a ‘green fields’ operation, our 21st Century technology and lean business practices mean we can deliver a Ferrari-type network for Corolla-type pricing.”

The company is privately owned and funded, with 30 percent equity held by New Zealanders. It is independent from the Telcos  operating in New Zealand.

FX Network’s partnership with REANNZ  follows the announcement  in April that FX Networks  had signed an agreement with Telecom Wholesale for the exchange of local internet traffic (local peering) at 19 of  Telecom’s points of interconnection – 39 currently available) around the country,  laying the groundwork for the “most efficient routing” of New Zealand’s growing volumes of Internet traffic through New Zealand’s two main internet backbones.

One of the regions on the University of Auckland portal of NZVWG grid which should benefit from both the KAREN decision and local "peering."

Peering allows traffic to be exchanged on a local or regional basis rather than transported back and forth throughout the country to be exchanged in Auckland.

Announcing this agreement the two companies said, “With the Government’s $1.5bn ‘Ultra Fast Broadband’ and $300m ‘Rural Broadband initiatives both on the horizon, the agreement paves the way for a whole new range of competitive broadband packages to be developed by ISPs and other service providers.”

FX Networks Jamie Baddeley said at the time of the agreement  that it meant  that the Governments investment of $1.8bn in urban and rural broadband “will now be able to run local content in a fast and efficient manner.

“This is a big step in New Zealand’s digital transformation that will revolutionise many aspects of society including health, education, commerce and entertainment,” he said. “…  I think many ISPs are going to have to rethink how they charge for traffic and there will now be competitive pressure to separate international traffic from local usage and charge accordingly.”

Ernie Newman, TUANZ

Senior industry consultant Dr Murray Milner said: “This is a very positive outcome with the industry tackling a major issue that is fundamental to the success of the current fibre roll-outs. Local peering means that internet backbones will not be clogged up with local traffic and we will see smart uses of the capability in areas like healthcare where digital X-rays can be shared simultaneously in full definition.”

Ernie Newman, CEO of TUANZ said: “Peering has been on the table for a number of years as one of those too hard issues, after some carriers depeered from the earlier system a few years ago. It was the users who bore the brunt of that with traffic romboning to Auckland when it didn’t need to, or worse to the USA. I’m delighted to see industry players resolving this issue without the need for regulation or government intervention and users will benefit from better performance and lower charges. What’s emerging is the national digital architecture that TUANZ has been calling for.”

NZ Virtual World Grid hosts

international  guests

NZVWG Auckland portal now accepting

‘resident’ avatar applications …

Educause Roundtable meeting on New Zealand Virtual World Grid

The  University of Auckland portal of the New Zealand Virtual World Grid (NZVWG)  has successfully hosted its  first international seminar, attracting  a number of leading MUVE educators and researchers from  around the world.

The meeting coincided with the announcement by Dr Scott Diener (SL: Professor Noarlunga), the virtual meeting host,  that the University of Auckland portal of the grid, although  still in a trial phase,  was now open for  virtual-world users to apply for ‘free’ registration from the Auckland portal.

It also coincided with a ‘demonstration’ of just how easy it is to teleport an avatar from the University of Auckland portal MUVE on the NZVWG ‘Hypergrid’ to the MUVE of   the University of Otago and return with inventory intact and retention of all abilities.

The NZVW Grid based on OpenSim software has grown out of the original ONGENS  grid, developed by the University of Otago in concert with the University of Canterbury, and the University of Auckland.   Weltec has also developed a portal for the grid and Nelson Marlborough Institute of Technology has associate status.

Welcoming the 20 plus guests from Educause’s Virtual World Roundtable  to the meeting in the Great Hall of “Kapua Castle” on the island of Kapua 3 in the New Zealand Virtual World Dr Diener said, “This is a really exciting development for us.

“We are stand-alone…we run our own asset server (database) with  the University of  Otago and Canterbury University having  similar setups, which have been linked together.”

Members of the Virtual Worlds Roundtable, who have previously visited a number of other Virtual Worlds  as a group for their meetings to assess and monitor MUVE development around the world praised the  apparent stability of the University of Auckland portal MUVE, the ease of entry, the fact  that it was open source and free, and  the  use of the Hypergrid, which opens up possibilities for easy, transparent connections to tertiary institution   MUVEs around the real world.

“We have found the Hypergrid does work, albeit with problems, “Dr Diener said, explaining that the goal of NZVWG was first to experiment and eventually to link to other grids.

Detailing the  setup of the MUVE, he said, the Auckland University portal is running on two virtual servers (VMware), and has a total capital investment of some $NZ10,000 ($US7000). This compared to an investment of say $US55,000 for signing up for SL Enterprise (previously Nebraska), the Linden Labs’ “behind the firewall” solution for standalone virtual worlds.

The Auckland MUVE is running on two dedicated, virtual machines with one server running a database and six sims. CPU usage has never got above five percent. Freeswitch voice is available on the MUVE but not yet completely activated.

“We can duplicate them (the virtual machines) in about 30 minutes – to scale if necessary,” he said in answer to a question, adding that OAR content was backed up automatically.

A  University of Auckland staff member is assigned one day a week to the MUVE , he said, with most of the work involved with things like getting voice working, and getting the Hypergrid fully functional.

He said the portal had been created out of his own budget as associate director of IT Services at the University of Auckland.

Dr Diener's Kapua Castle where the Roundtable meeting was held in the Geat Hall.

The portal, Dr Diener said, “is focused mostly on proving the concept of Hypergrid.”

“This is how our Writing Center began,” Iggy  Strangeland, of the University of Richmond, observed. “I bought a server out of budget, and then eventually got it supported by our data center. Now they maintain it and I just design content.

“We proved the concept. If it works for 2D Web, it can work for Virtual Worlds,” Strangeland said.

The major current problem with using the NZVWG MUVE for education purposes was the fact that there were as yet few resources “in world” … “all scripts have to be brought in,” Dr Diener said.

Given success for the NZVWG, however,  Dr Diener said, he would be excited to work on connecting  the that portal  with any other university  grid in the world.

Commenting on this, Lindy McKeown, of the University of Southern Queensland, said education.au in Australia was trying to set up a Hypergrid for all Australian universities to join.

Dr Diener, who is also a Lecturer at the University of Auckland, is well-known in Second Life and virtual world education circles around the globe for his and his associates’ creation of successful medicine/nursing/architecture simulations on the three University of Auckland Second Life islands in Second Life, the first of which was “Long White Cloud”.

Dr Diener mentioned that the “very active” New Zealand virtual world  group  VLENZ was represented at the meeting by Nelson Marlborough Institute of Technology  and Second Life Education New Zealand Project founder and joint leader,  Dr Clare Atkins (SL and NZVWG: Arwenna Stardust). Dr Atkins, on behalf of SLENZ and NMIT, operates two islands in Second Life, Koru and Kowhai.

“I think it WILL be a viable alternative (to Second Life) soon,” Dr Atkins said.

Other speakers agreed with Dr Atkins’ view that NZVWG and OpenSim were a good replacement for Second Life: “for me (as an educator) one of the huge benefits to OpenSim is that we can use it with under 18s,” she said.

Visitor Margaret Czart, of the University of Illinois,  said that all of the virtual worlds the Virtual Worlds Roundtable group had visited over time had provided good alternatives to Second Life but, “it is not so much the place but how you run it.”


A sitting room in Kapua Castle.

Dr Atkins’ and Czart’s comments about possible replacements for Second Life followed a remark that the Linden Labs’ position of Second Life education guru Pathfinder Linden had been disestablished and that the Lindens appeared to be showing  less interest in education.

Lindy McKeown foresaw the development of a “Hypergridded federation universe of locally-hosted worlds with some access by others but some private spaces” as appearing to be “a great education alternative for many reasons.”

But, she added, that for these alternative worlds to be successful “we need an SLexchange type (virtual worlds sales) system for other grids since Linden Labs had bought out virtual world goods sales competitors.

Iggy Strangeland replied that http://imnotgoingsideways.blogspot.com/2009/11/alternatives-to-xstreetsl.html was a good source for other sales portals. Lindy McKeown added that one also could buy OAR files full of content one  the net and there were lots of free ones too.

James Abraham (SL: Calisto Encinal  and http://calistoencinal.spaces.live.com/) said he was writing a grant to  “roll out a 10 college zero-cost OpenSim virtual world program for the Maricopa Community College District [James Abraham’s Mi Casa Es Su Casa won a prize for full sim builds at the recent SLPro! Conference sponsored by Linden Labs for Second Life content creators.]

On this point AJ Kelton, director of Emerging Instructional Technology at Montclair State University, founder and current leader of the EDUCAUSE Virtual Worlds Constituent Group and Roundtable moderator, agreed with Mirt Tenk who suggested that it would be good for tertiary education providers to share the “stuff  WE have built in Second Life as  open source for OpenSim users. Others agreed with this view, including Dr Atkins who noted that all SLENZ Project builds were free and open source.

Asked how close he thought tertiary educators were to replacing Second Life with other virtual worlds, Dr Diener said, “ I don’t think we ARE close … and in fact, I don’t think that is even the question…I think we need to ask how we can augment our Second Life resources with Virtual World like this.”

There was also a question, raised by Liz Dorland, of Washington University, in St Louis,  and others, of the importance of virtual world students and educators being able to connect with the rest of the world community as they could in Second Life.

Dr Atkins said that she thought the “richness of Second Life and its diversity” would be hard to grow in an OpenSim environment although other speakers noted interoperability between all MUVEs, including Second Life, to get the best of all virtual worlds, was a possibility.
