Strategic Plan for the Development of Computing Services Centre
K.H. Poon, Director of Computing Services
In the past 12 years the Computing Services Centre, though having
undergone a series of changes, has successfully created and maintained
a first class computing environment for the community of the University
. Up to now we have by far one of the largest and most sophisticated
networks, known as CTNET, in the territory. CTNET connects 50
departmental LANs which link up nearly 5000 computers in campus
including some 100 network servers of various capacities, 4400
PCs and over 500 Unix workstations. Off campus access to CTNET
is provided through Internet and also a modem pool with 250 dial-up
lines. Apart from a rich collection of software packages for support
of teaching and research, the information systems available on
CTNET now offer integrated and diversified electronic information
and services from within the campus as well as resources around
the world. Information kiosks are also set up in public locations
to allow convenient use of these systems outside the Centre and
staff offices. CTNET has become the indispensable facility for
almost every campus activity.
The Computing Services Centre still operates a large central student
terminal and teaching facility which contains 600 workstations
and 12 computerized teaching rooms (also called teaching studios),
equipped with high quality computer screen projectors. This facility
has been very popular and the utilization is extremely high during
term time.
Following the decentralized budget policy, departments become
autonomous in the development and support of their computing facilities.
As a result, the Computing Services Centre is gradually evolving
into a service bureau and has to compete with competitors from
within and outside the University. Nevertheless the Centre manages
to retain its competitiveness in the provision of its services
and remains as the primary service provider for almost all departments.
The Centre now still manages and supports 90% of departmental
LANs and provides training, consultation and technical support
to the majority of academic as well as administrative staff.
As information technology will continue to permeate the University
community, CSC, as the central academic support centre, must maintain
its momentum in the development of campus-wide computing infrastructure
and in the innovative use of computing technology so as to retain
our competitive edge for the University. Otherwise our University
will be lagging behind and gradually be eclipsed by its competitors.
It is envisaged that the Centre will focus on the following areas
in the next few years of its development:
- Networking
- The existing CTNET was designed based on the blue-print made in
1990 and is not the most advanced by today's standard. An upgrade
project has been taking place to embrace the latest technologies
into the network so that it will be able to support high speed
multimedia networking as well as adapt to dynamic adds and changes
in network connections. It is perceived that in the near future
ATM (Asynchronous Transfer Mode) technology will be widely used
for carrying data, voice and video, and that there will be no
distinction between LANs (local area networks) and WANs (wide-area
networks). However, ATM technology is still not fully mature at
this point of time and its many standards are yet to be finalized.
The Centre will closely monitor such technology and take cautious
steps to avoid unnecessary investment and to ensure its costeffectiveness.
It is envisaged that Internet will continue to grow at an extraordinary
speed and ATM technology gradually becomes mature, all future
networks on this planet may become part of the Internet eventually.
CTNET will be transformed into an Intranet for seamless integration
with the Internet while providing internal information database,
groupware application and decision support systems with the necessary
security protection.
- Remote Computing
- Predicting that demand on computing facilities for study, teaching
and research will continue to grow but provision of additional
student terminal rooms will not be possible with the limitation
of campus space, our development should therefore focus on extending
support of remote and roamabout access to the campus network.
This will mean to expand considerably remote access facilities
in terms of quantities and bandwidth to allow more students to
use the network at home as well as telecommuting, and to install
plug-in facility in most classrooms and the Library for convenient
connections to the network with notebook computers. To ensure
the success of this approach we must emphasize the development
of access method which should provide a uniform environment for
network access within campus and from remote locations.
- Supercomputing
- As a result of the trend of distributed computing most of the
computer applications in teaching and research nowadays can be
handled by PCs and Unix Workstations. The use of central host
computers are mostly used as servers to support applications,
file services, database, communication, computation, etc. Besides
upgrading the desktop machines and setting up of server farms
for providing various advanced network services, we also see the
need for a supercomputing or massive parallel processing machine.
As commonly known, for large scale or computation intensive research
work, a high speed computer beyond workstation and compute server
level is indispensable. Since other universities in Hong Kong
have already possessed computers of super-computing level, we
might lose our competitive edge if we fail to do so in the near
future.
- Multimedia
- Multimedia technology is emerging in almost all areas of computer
applications. With the upgraded campus network and also with the
significant decrease in cost of hardware and software, we envisage
that, in a couple years' time, all our desktop computers would
be equipped with multimedia devices. Multimedia software will
become the norm rather than specialized applications. Computer
presentation, interactive teaching and learning, video conferencing
and video on demand system etc. will become the popular methods
and tools for teaching. The Computing Services Centre should therefore
well prepare itself to support this new environment and also should
place more efforts in helping its users to migrate to this challenging
era of computing.
- Public Information Systems
- Our Centre will continue to develop and enhance our integrated
information systems to provide additional services as well as
to make the environment more user-friendly. We also expect that
our systems will gradually become part of Intranet and be more
accessible to users from the Internet world. To be in line with
the University's goal of becoming an internationally recognized
university, we should not focus only on facilitating electronic
communications and information retrieval as at the moment; instead
we must aim at building up our information resources locally and
make them available to international academics through Internet.
- Management Information Systems
- The existing administrative data processing systems of the University
were first developed some 10 years ago. Although they have been
enhanced from time to time, yet they still remain as software
of the older generations. To keep pace with the modern trend we
must migrate from the conventional development method to client/server
environment and use objectoriented approach. With the maturity
of multimedia technology, graphics, voice and video would be incorporated
in application systems to further enhance user-friendliness. Moreover,
the capabilities to handle both English and Chinese characters
for input and output will also be gradually implemented.
Apart from moving towards a more open central MIS environment,
the Centre will continue to develop the Distributed Departmental
Systems (CITYDIS) to facilitate daytoday operations
of departments. These departmental systems will be fully integrated
with the central systems.
- External Links & Professional Services
- The Centre will continue its effort to build its link with other
universities as well as industries with a view to enhancing the
Centre's abilities to serve its users. At the moment, we already
have several cooperative projects with a few universities in Hong
Kong as well as in China. We envisage this development will continue
and be strengthened in the future. In the past, our participation
in providing community and professional services has been relatively
inactive. In future, we shall focus more in these areas as we
see that these are equally important for the image building of
the University and the Centre.
- Quality and Cost-effective Services
- Computers is now an integral part of the University in teaching,
research learning, office automation and administration. It is
envisaged that the Centre's responsibilities will continue to
increase with time, though additional manpower resources would
not be forthcoming in view of the University's vow of "doing
more with less". Without the sacrifice of quality, the Centre
should aim to adjust the mix of its staff in occasions of natural
turnover in order to gain more hands with a reduced budget. Benchmarking
is planned in the near future to ensure that our provision of
computing facilities and user services is the top of the class.
We believe that in the current increasingly harsh competitive
climate, the Centre must continuously examine its roles, retire
the old practices and procedures, abandon outdated principles
and adopt a new set so that the Centre can be flexible enough
to adjust quickly to the changing conditions, lean enough to beat
its competitors, innovative enough to make its service and environment
technologically fresh, and dedicated enough to deliver maximum
quality service to its users.
