Early HARNET Era before 1991

HARNET: established in 1985 based on DECnet and UUCP 4800 bps dialup connection

Connected to BITNET in 1989 via a 2400 bps leased circuit to Yale University

Connected to Internet in 1991 & High-speed wide-area network backbone linking up the campus networks of the JUCC members

Provides Internet network services to JUCC member institutions, affiliate and network members

HARNET/Internet Era 1989-2002

Growth of local HARNET 1993 – T1-ring network 1995 – T1-ring to T1-star 1997 – ATM at 10Mbps 2000 – ATM at 30Mbps 2001 – ATM at 45Mbps 2002 – ATM at 60Mbps

HARNET/Internet Era 1989-2002

Growth of HARNET/Internet bandwidth 1992 – 64K 1993 – 128K leased circuit 1995 – T1 (1.54Mbps) 1996 – E1 (2 Mbps) 1997 – 6M 1998 – 12M + Netplus 1999 – 12M + 12M 2000 – 48M 2001 – 72M 2002 – 96M

HARNET/Internet2 Era 2002-Present

HARNET connected to Internet2 in October 2002

Via the STARTAP at Chicago through a 45Mbps link

Facilitated researches that require a high-bandwidth connection to the Internet2 backbone and NGI (Next Generation Internet)

HARNET/TANET Connection 2002: connected to TANET via their

HK collocation site at 155 Mbps HARVNET: for local and international

inter-institutional multi-party video-conferencing

HARNET/CERNET Connection 2004: upgraded from 2Mbps to

155Mbps 2004: set up an IPv6 BGP peer

with CSTNET using IPv4 tunneling 2005: connected to CERNET2 with

IPv6 BGP peering

On-going Development

Optical HARNET a high-speed multi-gigabit optical

network infrastructure for the Next Generation HARNET

provides on-demand lambda bandwidth between institutions for research applications

connecting advanced international R&E optical networks

Optical HARNET – prospective applications high Performance and GRID computing

applications multi-party high-quality high-definition

videoconferencing VOIP (Voice Over IP) deployment off-site disaster recovery data centers remote SAN through fibre-channel

connections tele-medicine, digital libraries, virtual

classrooms, etc.

Optical HARNET – initial set-up a 10Gbps dual-ring backbone fiber diversity on-demand services of at least two 1G

Ethernet ports and one 2G Fiber channel port at each institution

Optical HARNET – initial set-up flexibility in new lambda setup support future expansion using WDM

technologies with minimum 16 lambdas

supports bandwidth allocation at the sub-lambda level for easy re-configuration

CODEC for high-quality video transmission

Future Directions Continue to develop JUCC’s leadership

in Next Generation networks in HK Increase cooperation with international

high-speed R&E networks Develop high-quality video-

conferencing over IP network Foster inter-institutional and

international cooperation on network security, new IT technologies, applications and training
