The System Administrators Guild of Australia (SAGE-AU) has raised strong concerns regarding a report issued on 28 July 2008 by the Australian Communications and Media Authority (ACMA) entitled, "Closed Environment Testing of ISP-Level Internet Content Filtering".
The artificial conditions of the testing methodology, together with unacceptable limitations in the test's terms of reference, combine to reduce the usefulness of the report for real-world conditions.
Mark Newton, SAGE-AU member and network expert, pointed out, "The baseline performance test featured 30 users on a gigabit switch saturating the test web server at 425 megabits per second (page 30), and stated that that would be equivalent to around 20,000 end users each on 1.5 Mbps connections (page 31). However, 425 Mbps divided among 20,000 end users actually gives each user 21,250 bits per second, around half of what can be achieved with a dial-up modem."
Technology administrators meeting at the SAGE-AU 2008 conference in Adelaide will discover how to extract a "green dividend" through the more efficient deployment of computer networks and systems.
The two-day conference, preceded by three days of technical tutorials, will have a major focus on green computing and sustainability, including server virtualisation, which delivers greater computing power while reducing the carbon impact by producing less heat and consuming less energy.
A keynote speaker is Leonard Cohen, the founder of the Australian Carbon Biosequestration Initiative, who will talk about the cost of embedded and recurrent energy in computing technology.
To emphasise the green theme, the conference has achieved CO2-neutral status by buying carbon credits to offset the environmental impact of the event. Also, each delegate will receive a CarbonZero Green Gift pack containing a Golden Wattle seedling and planting guide; a carbon credit certificate for the conference; brochures from Canopy and Greening Australia and a magnet or pen.
SAGE-AU is a not-for-profit professional organisation representing system administrators in Australia. System administrators are the technology experts who keep computers working for the rest of the world. In its simplest form, system administration ensures the reliability of computer systems for end users, but includes the art of system recovery when the worst does happen.
SAGE.AU President Donna Ashelford said conference delegates would learn how to deliver a "green dividend" to their organisations. "As well as a benefit to society, green computing provides a direct return to the business," she said.
Broadband product specialist Billion is now shipping its latest routers, the Billion BiPAC 7402NX, which provides draft 802.11n wireless and 1Gb LAN support as well as 3G and ADSL2+ capabilities.
The Billion BiPAC 7402NX, with a $499 RRP, is available through the national reseller network managed by Billion's Australian distributor PC Range. Product images for the BiPAC 7402NX can be downloaded from http://www.impress.com.au/content/view/259/67.
The BiPAC 7402NX is a Virtual Private Network (VPN) firewall router that can communicate via both wired and wireless Wide Area Networks (WANs). In wired mode, it uses an ADSL2+ broadband service over a copper telephone line, but if that link is disrupted, the 7402NX can stay online wirelessly through automatic failover to a 3G mobile telephone network.
