The question 

A question has recently arisen about REANNZ’s attitude to collaboration over getting the physical connection to KAREN. The answer is quite straightforward from our perspective.

Network engineer or specialist in network measurement and monitoring? You can not miss the perfSONAR workshop at APAN26 Sustainable Networking, 4-8 August.

Calling all network graduate students and researchers: get involved in the APAN26 Sustainable Networking conference in Queenstown by submitting a paper to the Network Research Working Group.

The APAN Network Research Working Group is holding a one-day workshop on 4 August as part of APAN26.

REANNZ has released the first KAREN Members Report. This report provides an overview of the activity undertaken to support both members and the network for the six months to 30 June 2007.  It also includes information about the performance of KAREN during this time. 

The primary KAREN VLAN was changed to support a 9000 byte IP MTU on Tuesday, 26 June.  This change allows members to take advantage of the low latency, high bandwidth characteristics of KAREN to achieve greater data throughput than conventional networks permit.  This is achieved without impacting the support for existing traffic.

KAREN members have already been taking advantage of the possibilities that this change allows. Ben Yeldon of AUT and Craig Miskell of AgResearch have performed some initial testing.

"Testing has shown a 3-fold increase in overall throughput when using large (4000byte+) frames vs 1500byte frames", says Craig.

This performance gain was seen without performing any tuning of the systems involved.

Several network access providers have enquired about the possibility of providing aggregation services, ie sharing a core KAREN connection with more than one end customer.  Such a service can be useful where customers do not have the funding available to purchase a 1Gb/s last mile connection or the required equipment to deal with the routing and other specifications of a core KAREN connection. 

Through REANNZ's international partnership with Taiwanese network, TWAREN, and Singaporean Network, SingAREN, KAREN members now have improved access to their peers in these countries. KAREN recently signed Memoranda of Understanding with TWAREN and SingAREN confirming peering arrangements, and as a result widening the reach of KAREN and speeding up access to international collaboration partners in these countries.

Peering is an interconnection of separate networks or groups of networks allowing the exchange of traffic between network customers.

NZNOG 07

REANNZ was represented for the first time at the NZ Network Operators Group (NZNOG) 07. NZNOG provided an excellent opportunity for some of us to get together and discuss KAREN, the status of connections and some of the future possibilities for the network and those who use it.

Hi all, as you know KAREN is now live. We terminated the first connections on 17^th December and now have seven Active members peering via IPv4, and one who is also peering via IPv6. Currently connected members are:

IPTV trials on JANET go mainstream

UK Company Inuk has been trialing an IPTV multicast service over the UK's advanced network, JANET, for the last year.

For the technically inclined, APAN26 features hands-on training and know-how workshops on advanced networking technologies and equipment.

KAREN video conference trial participants are making the most of this service and simplifying real-time collaboration. Are you taking advantage of this fantastic service?
