To afford modeling of SoS, the whole diversity of their components and structures is represented in CSL as Communicating Structures , uniform and systematic compositions of a small number of simple basic concepts that describe communication , data traffic , and data placement in systems. SoS are represented as hierarchical networks of nodes . The nodes have memory that may contain items .
Nets are sets of links that connect the nodes.
The items are generated in some nodes and move from node to node along links concurrently with some delay. The item generation, transformation and movement is controlled by parallel processes associated with nodes. Items, nodes, memories, and nets may be elementary or may be aggregated objects. In general, CSL emphasizes those system features that generate and manage the system traffic. To access the report on CSL click here .
