The Kiwi Advanced Research & Education Network (KAREN) is a next-generation telecommunications link for New Zealand educators, researchers and innovators. KAREN is the New Zealand implementation of NREN.
Target Audience: Massey University staff
- Whenever a user uses the Massey Network to visit a web resource - such as a website from an overseas academic institution that is part of NREN - they will be using KAREN
- KAREN does not provide access to websites that are not a part of the NREN network; Massey's standard internet connection is used. For example, Google is not on the NREN network; therefore, it is accessed via Massey's internet connection
- Internet users will not notice a difference between accessing a website through KAREN or through the normal internet. A device called a ‘router’ automatically applies the appropriate connection
- While KAREN may be transparent in use for Massey network users, it does provide benefits: it is faster, and it is a fixed cost for the university, which means there is no charge for sending data on the network
KAREN is an attempt by the New Zealand government to aid the collaboration of research between domestic and international academic institutions. An example of a project that could benefit from KAREN is:
A group of Massey University researchers are working with radio data from satellite dishes. Large volumes of data to work on is generated, so a fellow researcher - located in Sydney - offers to help. KAREN makes it possible to send the data to Australia at very fast speed. Additionally, there is no cost for the data transfer as the only fee involved is access to the network.
As Massey University is paying for access to this service, it is up to Massey researchers to use the service.
There is no cost to departments (outside of ITS) for access. Everyone that has a Massey Network User Account has access to KAREN.
- Massey has five 1Gig connections to the service, at : Albany, SHORE, Hokowhitu, Turitea and Wellington
- The service is IPv6 capable. Massey will be deploying IPv6 at each site Q4 2007/Q1 2008
- Multicast will be enabled. There is a technical issue with our Checkpoint firewalls that is currently preventing the use of multicast
- The connection from KAREN to Australia is 155mbit. The connection to USA is 625mbit. NOTE: The bandwidth to USA and Australia are going to grow when bandwidth demands require a faster speed
- The KAREN network exhibits a problem shared by all 'Long Fat Pipes'. You need to to tune the TCP window sizes of equipment at each end of a conversation in order to see a significant improvement in throughput for a single data transfer. However, it will support a significantly higher volume of concurrent connections with little or no degradation in performance or throughput
