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

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
On-going Development
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.
On-going Development
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
On-going Development
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
