In this paper we study the behaviour (processes) of reaction systems where the context is not arbitrary, but it has its own structure. In particular, we consider a model where the context for a reaction system originates from a network of reaction systems. Such a network is formalised as a graph with reaction systems residing at its nodes, where each reaction system contributes to dening the context of all its neighbours. This paper pro- vides a framework for investigating the behaviour of reaction systems receiving contexts from networks of reaction systems, provides a characterisation of their state sequences, and considers dierent topologies of context networks.
