Try the Internet Proxy Server

ITS has installed an Internet Proxy Server to speed up access to the Internet. The Server acts as "memory" storing information which is frequently accessed. When a user requests the same information on the Internet, the information will be provided by the on-site proxy server instead of down loading from the original source.

This technique is widely adopted by other Universities which has the effect of speeding up the delivery of information. Our statistics show that on average, the transfer time without using the proxy server is 15.53 seconds per request whereas only 9.78 seconds are required when the proxy server is used. An average improvement of 5.75 seconds, or 37% per request.

The name of the Server is To enable the Proxy service in Netscape for quicker information:

Compuserve- Maintain Connection with PolyU from Overseas

To facilitate more cost-effective E-mail communications with PolyU for staff travelling overseas, ITS has opened an account with CompuServe, an INTERNATIONAL Internet Service Provider (ISP). This service enables a computer user to connect to the telephone system in an overseas location and to dial a local telephone number which provides access to their E-mail account in PolyU. Staff travelling abroad will then be able to stay in contact with colleagues back in Hong Kong. No international calls have to be made at all to get connected to Hong Kong or other locations, thus making remote access much more economical.

We have tested the service and found it to be reliable. The user requires a computer, probably a laptop, with a suitable modem which can be connected to the phone system. There are a few settings to enter and a fairly simple procedure to follow, and we will provide training for users.

Anyone who is interested to use this service will first receive endorsement from their Head of Department and then contact the ITS Help Desk at least two weeks in advance of their intended use. They need to bring their laptop to our Help Desk for installation of the appropriate software. Our staff at the Help Desk will also advise on the plugs and connectors necessary for the particular destination and provide suitable training for operating the service. Insurance cover for your laptop can be arranged with the FO.

Good News!!!

Video Conferencing Coming onto the Campus

Pilot testing of the Integrated Services Digital Network (ISDN) technology has been undertaken by ITS with a view to facilitating teleconferencing and multimedia communications with external or overseas organizations and institutions. Installation of such ISDN facilities for high quality teleconferencing is planned at strategic locations on campus.

At the same time, desktop video conferencing facilities will also be installed in all the multimedia PCs in the WISE Lab in our P Core SCC during the coming summer. As the next stage of development, ITS plans to introduce and assist those departments and users who may wish to implement and experience video conferencing facilities on their desktops, through a small investment on video equipment and software.

To support the PolyU's Vision 2001 in which Information Technology (IT) is identified as a critical issue in steering PolyU towards a "preferred university", the Office of Information Technology Services (ITS) embarked on the preparation of an Information Technology Strategic Plan for the 3-year period 96/97-98/99 in November 1995. The major objective of the Plan is to ensure that an up-to-date, efficient and cost-effective Information Technology environment is provided and continuously maintained so that the teaching, learning, research and administrative activities of the University can take full benefits of the latest technologies.

With the support of the Information Technology Services Committee (ITSC), the IT Strategic Plan has subsequently been submitted to and endorsed respectively by the Senior Academic & Management Group and the President's Executive Group. In January 1997, budgets began to be available by phase for the implementation of the Plan, and ITS has since been planning and working full swing to roll out the implementation of the various IT initiatives and projects identified in the Plan.

The IT Strategic Plan has identified a number of initiatives which ITS would need to focus in the coming few years in order to effectively support PolyU's strategic vision. They fall into 7 areas as follows:

IT is a rapid-changing technology. It is expected that the IT Strategic Plan will be continuously reviewed and modified to take account of evolving user needs in consultation with users as well as new technologies. The successful implementation of the Plan will rely on the concerted effort of ITS and users of the PolyU community.

Among one of the "Frequently Asked Questions" received from the Virtual Help Desk on our WWW Homepage is : Should I Upgrade to Windows 95?

To facilitate users to choose the best operating system suitable to their personal needs and to help them avoid/overcome expected difficulties in using Windows 95, ITS has conducted a comprehensive study on Windows 95 quite some time ago. The user reference guide on the Windows 95 platform can be available from the User Services Section's Virtual Help Desk under the ITS WWW Homepage. Key features of interest are reproduced below.

Recommended Hardware Requirements

Computer 486 / Pentium with a hard disk with approximately 100 MB free disk space for typical installation
Memory 16 MB RAM recommended
Display SVGA with video card capable of outputting 16­bit TrueColor
Optional Network Card, CD­ROM drive

Operating System Options for Windows 95 Installation

MS­DOS version 3.2 or higher
Windows 3.0, 3.1, and workgroups 3.11
OS/2 (configured to dual boot with MS­DOS)
Windows NT (configured to dual boot with MS­DOS)

When installation is completed, Windows 95 will completely take over as the operating system.

Plug and Play (PnP) Feature

Windows 95 supports Plug and Play both during startup and dynamically while the system is running. In short, PnP means that during installation of any devices, the configuration of the PC is changed automatically with no manual input required. Each time Windows 95 is started, the hardware is polled for its identification and specification information. When a PnP component device is added to the system, the device will automatically pass its identification and specification information to the operating system and will then take care of any configuration issues.

In order to perform complete PnP functionality, both of the BIOS and hardware devices should be PnP enabled (most of the new BIOS and hardware devices are PnP ready).

Integrated Networking

The networking functionality is fully integrated in Windows 95. It supports multiple protocols, multiple redirectors, universal naming convention, and more. As mentioned, the networking features of Windows 95 support plug and play devices, which means that the network connections would be automatically configured when a device is removed or added to the system.

Other Windows 95 network features include:

Robust networking components using no conventional memory
Easy, graphical configuration for all networking components
Automatic set up of Windows 95 on networked workstations
Simultaneous connection to multiple networks on a single computer
Plug and Play networking support
Automatic reconnection for lost server connections
Long filenames for network resources

Comparison: Windows 95 vs. Windows 3.X

Windows 95

Window 3.X
CPU utilizes the 32­bit architecture of the latest 486, Pentium, and the coming P6 processors based on 16­bit architecture of the 286
Plug and Play supports plug & play, adding of new PnP hardware is easy but may be hard to get the Windows 95 version driver for some old devices manual configuration
Networking advance networking protocols and tools, powerful and user friendly interface basic networking protocols
Disk Space and Memory requires more hard disk space and memory - see recommended configuration above can run on lower hard disk and memory configurations
Applications runs DOS, Windows 3.x and Windows 95 applications runs DOS and Windows 3.x applications
Performance as Windows 95 applications are optimized for the 32-bit architecture, they can run faster than the Windows 3.x applications runs applications slower

Learning Curve

Users should recognise that most of our experiences in DOS and Windows 3.1 are not applicable to the Windows 95 environment. However, the learning curve for Windows 95 is not steep as most of the hardware and memory settings are taken care of by the system which enable users to concentrate on familiarising with the new interface and functions.

Support for Windows 95

Microsoft has made Windows 95 much more stable compared to when it was first released. ITS now provides level one (comprehensive and full range) support for Windows 95 users. Any enquiries and requests for assistance on Windows 95 may be directed to the ITS Help Desk and Hotline. Training courses for staff on Windows 95 will also be available this summer and details can be found in ITS's monthly staff training schedules.

Dial-in Modem Pool

To advance the speed of remote access to computer resources on campus, ITS has upgraded the dial-in modem pool with more PPP connections and enhanced connection speed from a minimum of 14.4Kps. to a maximum of 33.6Kps.

New Setting of Modem Pool Effective 1 May 1997

Two new areas of supporting services from ITS in the EOD area were also announced during the Symposium:

Web-based Interactive Systems for Education Laboratory (WISE Lab)

Opening in May in room P504 at the P Core Student Computing Centre, the WISE Lab contains 20 multimedia computers equipped with full screen full motion video playback, connected to a central Video Server and the WWW server via high-speed network. Users can use the facility to view computer-based, multimedia educational materials and courseware of various disciplines, developed by PolyU teaching staff or from outside sources for interactive and self-paced learning.

Multimedia Production Centre

A Multimedia Production Centre (MPC) is also being established under ITS to assist departments in the production of multimedia materials as well as to facilitate electronic publishing services. A full range of specialised equipment and expertise to cater for all aspects of multimedia production will be available in the MPC for staff who wish to develop multimedia material but who do not wish to perform the more laborious technical tasks that are associated with this endeavour. With full back-up by ITS, the Centre will have a wide range of video and computer equipment as well as programming, design and videographic expertise.

Homepage Competition Results Announced

In response to the President's address at the launching of PolyU's WWW Services in February 1996, in which he called for the institution to fully exploit the opportunities offered by the Internet for its teaching, learning, research and administrative services, a PolyU WWW Homepage Competition was organized by ITS.

As a means of furthering and communicating the goals of PolyU's Vision 2001 and in acknowledging the rapidly growing influence of information technology in both education and administration, the University actively promotes its Web-based facilities in pursuit of its vision of becoming a preferred university, offering preferred programmes, producing preferred graduates. The competition is intended to stimulate activity towards this end. Two streams of the competition were held concurrently, one for departmental homepages and the other for personal homepages. All Departments, Offices, Centres and Units were invited and encouraged to create their own Homepage on the WWW. At the same time, staff members were encouraged to build their own Personal Homepages which can be linked to their Departmental Homepages.

The theme of the competition is "PolyU and The Internet - At Your Service". This reflects the focus on service which is pervading PolyU's operations, and is in support of other initiatives aimed at directing the development of the PolyU culture towards a customer orientation.

With the patronage of the President and the generous sponsorship of a number of corporations, the competition reached its climax on 22 April 1997 when the results were announced and prizes presented at the opening ceremony of the Symposium on Education on Demand. The entries were judged by a panel of public figures of the community with staff and student representatives and the results are as follows :

Departmental Homepage
Winner Pao Yue-Kong Library
1st runner up Department of Land Surveying & Geo-Informatics
2nd runner up School of Design
Special Merit Centre for Professional & Continuing Education

Standard PC Configurations for Enhanced Campus-Wide Support

In order that new IT facilities and services can be effectively and successfully implemented in the University and to enable users to take full benefit from the new technologies, the Information Technology Services Committee (ITSC), at its last meeting, endorsed the following guideline recommended by ITS on the minimum PC hardware configurations for campus-wide support:

effective date minimum PC configuration
1 July 1997 80486 PC with VGA graphic display
1 Jan 1998 80486PC, 66MHz CPU with 16MB RAM and VGA graphic display

In addition, as new versions of PolyU's administrative systems will require the configuration of a Pentium to run and to take full advantage of the new features, ITS recommends that with effect from 1 July 1997, PCs dedicated for running central administrative systems should conform with the followings:

Pentium systems with 166 MHz CPUs
300MB available hard disk space
running Windows v3.1.

Users are reminded that the use of the University's computing and electronic mail services carries certain responsibilities and obligations. In particular, a user is not allowed to transfer or resell network resources to anyone else, and E-mail should not be used for any of the following purposes:

commercial functions, such as marketing or business transactions
chain letters
broadcast messages which are likely to harass or offend other users
any communication which violates applicable laws and regulations

If staff or students are found to have allowed PolyU computing resources to be used by individuals outside the University, such abuse will be reported to the management, particularly when the misuse causes embarrassment to the institution or inconvenience/hardship to the public.
