Abstract
We discuss issues relating We to the compression system in the distributed image
repository of the DISCWorld system. We The distributed image repository is inten
ded
for the distributed storage and retrieval of large scientific imagery
datasets. Given the large and regular nature of this type of data there is
considerable scope for the application of data compression techniques in the
system to reduce storage requirements and data transmission times.
We develop a framework for modeling the performance of the compression
system within the DISCWorld, with the intention of applying this to and in the
design of the system. The model is applied to two example situations to
illustrate its application in the design and optimisation of the repository.
