Outline • A brief history • Experience • CNGI project • CERNET2 design
China IPv6 Efforts • 1998, CERNET-IPv6 Testbed • 1999, IPv6 demo system funded by MST 863 • 1999, CERNET-Nokia joint IPv6 project • 2000, NSFCNET funded by NSFC • 2001, IPv6 Router funded by MST 863 • 2001, IPv6 MAN demo system funded by CAS • 2002,6TNET by MII • 2002, IPv6-CJ funded by Chinese government and Japanese government started • 2003, CNGI project
CERNET IPv6 History • May 3, 1998, IPv6 on FreeBSD at Tsinghua University • Sept. 1998 first BGP4+ peer to Sprint (MRTd) • Nov. 1998, First 6Bone backbone node in China • Mar., 2000 IPv6 BBS--6th Galaxy opened • April 26, 2000 obtained sTLA (2001:250::/35 ) from APNIC • Aug., 2000《IPv6原理与实践》published • Sep. 25, 2000 CERNET joined IPv6 Forum • Jan. 2002 DRAGONTAP IPv6 IX is running • Jun. 2002 NSFCNET double stack is running • Sept. 2003 CERNET2 test nodes are running
CERNET IPv6 Testbed • pTLA in 6bone • 3FFE:3200::/24 • sTLA from APNIC • 2001:250::/32
