= Describing And Manipulating Experiment Topologies in DETER = This page describes the model, specification and implementation of DETER's topology description. A topology is the layout of an experment's physcial or logical environment including the topologies of its control and data networks. Because DETER experiments are intended to be large - thousands or millions of entities - DETER's topology system must support large scale * Specification * Operations - realize, initialize, etc. * Visualization We describe a model that suports these, an API that describes how to use the model and an initial implementation in the Descartes interface. == Model ==
