How do we know ISP-level filtering will work on the National Broadband Network when it was only tested on a 8 megabits per second network in the pilot?
A 100 megabits per second system was not available for testing under the live pilot. Enex TestLab conducted testing of ISP-level filtering on networks running at speeds of up to 8 megabits per second. This was the highest speed offered by any of the pilot participants. However, Enex TestLab reports that filtering technologies work in a variety of ways. Consultations with ISPs and expert technical advice confirms that there is no reason to believe that ISPs would not be able to choose a technology that filters a defined list of specific internet addresses (URLs) with no, or only negligible, impact on network speeds when utilising the National Broadband Network. A number of overseas countries have successfully implemented filtering of a defined list of URLs with no noticeable impact on internet speeds. For example, it is understood that British Telecom’s filtered network operates well in excess of 8 megabits per second. ISP-level filtering devices available in the market can handle 10 gi
