The Evolution of MAN - High Speed Connectivity for Local Area Networks
Professor J Hullett
Australian Telecommunications Research Institute
The
International Lecture
has become one of the Institution's
major annual prestige events. In 1996 it is being presented
by Professor John Hullett from the Australian Telecommunications
Research Institute at Curtin University, Perth. The subject will
be "The evolution of MAN - High Speed Connectivity for Local Area
Networks". This lecture is being given in Hong Kong, Munich,
London,
Edinburgh, Cambridge, Turin and Singapore.
Professor Hullett has chosen Cambridge as a particularly appropriate
venue.
The lecture will be given in the Wolfson Hall, Churchill
College, Cambridge on Wednesday 20 March 1996, commencing at 7.00 p.m.

Synopsis
Early demand for wide-area broadband networks is being driven
by the need to extend the operational range of Local Area
Networks (LANs) and to cater for new services such as
multimedia. The new type of broadband network which can
offer LAN performance within a metropolis is the Metropolitan
Area Network or MAN. For wide-area operation, the industry is
moving within the ITU to develop the Broadband Integrated Services
Digital Network, or B_ISDN, which will provide a complete range of
services from telephony through television to data. Information
for all services within the B_ISDN and MAN is conveyed and switched
in irregularly occurring fixed-size segments called cells. This
method of information handling is referred to as the Asynchronous
Transfer Mode, or ATM.
This lecture will describe the evolution of Metropolitan Area Networks
and ATM LANs, and the development of the Distributed Queue Dual Bus
(DQDB) technology on which the relevant standards are based.
Biography
John L Hullett
John Hullett
is a foundation Professor of Telecommunications at the
Australian Telecommunications Research Institute (ATRI), Curtin
University, Western Australia. His professional interests lie
in the fields of digital and optical communications and networking
where he has published extensively. He is the co-patent holder,
with Dr R M Newman, of the Distributed Queue Dual Bus (DQDB) patent
which describes the protocol used as the basis for the IEEE 802.6
Metropolitan Area Network and the ISO shared-medium ATM LAN.
During 1987-1990 he was Technical and Executive Director of QPSX
Communications Ltd, the company responsible for developing the
first standard MAN and the associated Switched Multimegabit Data
Service. He was the inaugural winner of the Charles Todd Medal for
excellence in communications.
