We first introduce a basic language where connections are reliable and immutable; then, we enrich it with two more advanced features for global computing, i.e. failures and dynamically evolving connections. In each setting, we use our formalisms to specify some non-trivial global computing applications and exploit the semantic theory based on an observational equivalence to equationally establish properties of the considered case-studies. %P 157-172 %I Springer %E Marie Jacquet %E Gian Pietro Picco %T Global Computing in a Dynamic Network of Tuple Spaces
