There is currently much interest in Integrated Services Systems which handle
within one network or architecture a mixture of data, graphics, video and voice, although
most of the work to date has concentrated on the voice and data services.
This thesis is concerned with the provision of graphics and video services alongside
the voice and data services over a Wide Area Network (WAN). The network concerned
in this thesis is the Unison network, which comprises several Local Area
Networks (LANs) interconnected by a primary rate (2 Mb/s) Integrated Service
Digital Link. [Continues.]
