TERENA compendium of national research and education networks in europe/traffic4.4 IPv6The 2005 edition of the Compendium showedthat universities were taking the lead in IPv6. Itwas suggested that it would not be unusual forat least some departments in a university to havea professional interest in a new Internet Protocol.140120Graph 4.4.2 IPv6 Traffic vs. Total IP Traffic80007000As can be seen from table 4.1.1, the numberof universities that have some form of IPv6connectivity has increased in the past year,both in absolute numbers and proportionately.Table 4.1.1 Universities Connected via IPv6, EU/EFTA# of Universities with IPv6connectivity% of Universities with IPv6connectivity2005 2006205 43115.4% 34.8%Terabytes (IPv6)10080604060005000400030002000Terabytes (all IP traffic)There are other indicators of the uptake ofIPv6, particularly within the NREN community.The GÉANT monthly reports give the volume ofIPv6 traffic for each NREN access (or group ofNRENs, as in the case of NORDUnet).200Q4 2003 Q1 2004 Q2 2004 Q3 2004 Q4 2004 Q1 2005 Q2 2005 Q3 2005 Q4 2005 Q1 200610000From the data, it seems that the growth in IPv6traffic on the GÉANT backbone has peaked,at least for the time being. It seems thatinstitutions are adopting the connection, but arenot using it.IPv6 trafficTotal IP traffic57
