RAND/UCSB NETWORK GRAPHICS EXPERIMENT
During the Network Graphics Meeting in July, several experiments were
outlined to explore graphics over the Network. One of these was the
use of the UCSB On-Line System (OLS) from graphic consoles at Rand.
The connection was completed in the latter half of August and has
been used on an experimental basis since then. OLS users from UCSB
and TRW (in Los Angeles) have visited Rand and accessed OLS via Rand
consoles and the Network. Thus, the first phase of the experiment
was completed in August.
We are still in the midst of the second phase of the experiment which
involves cleaning up the initial implementation and reviewing and
modifying our initial strategies for the OLS connection.
IMPLEMENTATION OF THE EXPERIMENT
UCSB has had a Network interface on the OLS for some time. For a
description, see RFC #74. The descriptions in RFC #74 were modified
to conform to current Network protocols (NCP and ICP) and to conform
to what we considered a general graphics description.
Basically, the OLS receives an EBCDIC-like input byte stream and
generates an unstructured graphical output stream. These protocols
will be documented at the completion of our experimentation and
presented at the Network graphics meeting in October.
The Rand Video-Graphics System (VGS) was used to access the OLS via
the Network. The Video-Graphics System and its consoles are
described in R-753-ARPA available from the Rand Reports Department.
VGS consoles had been connected previously to the Network via the
Rand Network Services Program (NSP). Originally, NSP was designed to
afford NCP checkout features, logging in to and use of remote systems
and access to UCSB RJE and UCLA RJS. An additional module was easily
added to access the OLS.
