Ross Cartlidge
Data Network Manager
Information Technology Services
University of Sydney

       Having graduated from the University of Sydney with an
       Honours degree in Computer Science, Ross Cartlidge was
       employed by the University Computer Service as part of a
       three man team to develop a terminal server network for
       staff and student terminal access.  This project called
       Sydnet involved the design of both hardware and software for
       MC68000 based systems utilising RS-232, RS-422 and IEEE
       802.3(Ethernet) communication protocols together with
       twisted pair, optical fibre and coax physical media.  Sydnet
       became fully operational in 1984 and supplied over 300
       terminals to university until it was replaced by a campus-
       wide TCP/IP network in 1988.

       In December of 1984 he moved to TIME Office Computers as
       part of the XLAN project development team. His primary
       responsibility was the porting of UNIX to a NS32032 based
       graphics-workstation, acquiring, in the process, first hand
       experience with UNIX system internals and local area network
       hardware and software.

       In October of 1985 he moved back to the University Computing
       Service to become part of the newly-formed Network Group.
       This group was formed to oversee the design and
       implementation of an integrated information service at the
       University of Sydney.  The resulting system is based on the
       Internet TCP/IP protocol, around which departmental local
       area networks are interconnected. His responsibility
       involved both the selection of the network hardware and
       software and in acting as a consultant to individual
       departments in formulating their network requirements and
       implementations.

       His work with the network group at the Computer Service has
       given him extensive knowledge of network standards and
       implementations, specifically in the Ethernet and TCP/IP
       field.

       In parallel with his network duties he was also involved in
       supporting the University's UNIX computers and developing
       applications for use with text formatting and graphics with
       PostScript laser printers.  Two components of this software,
       an N-UP prolog for arbitrary PostScript and a daemon to
       attach Unix pty devices to terminal server ports, were
       posted on netnews and now used in many sites around the
       world.

       His knowledge of networking and graphics has also helped him
       develop applications in the X-Window System and the Network
       extensible Window System(NeWS) developed by Sun
       Microsystems.

       He has worked extensively on establishment and development
       of the Australian Academic Research Network (AARN), an
       Australia-wide TCP/IP network connected to the US Internet.
       The AARN NSW Regional Centre is situated at Sydney
       University Computing Service.

       Ross is currently responsible for the design, implementation
       and management of the new data network for The University of
       Sydney. This network, which began installation in early 1995
       is based on ATM switching and fibre optics. This network
       will extend switched network services to the desktop at the
       University of Sydney.
