Structural and Behavioural Equivalences of Networks
We define an algebraic language for networks of synchronously communicating
processes. A node in the Network may have several ports; a port is either
external to the whole network or connected through a link to another
port. The language contains two types of operations: parallel composition
of two networks, and interlinking of two external ports within a network.
We interpret this language in two ways: first we give a structural
semantics, where terms are mapped to graphs representing the structure of
networks, and second we give a behavioural semantics, where terms are
mapped to behaviour schemes. A schema corresponds to a behaviour
parameterised on the behaviours of the network nodes. These semantics give
rise to structural and behavioural equivalences.
We compare the equivalences and give sound and complete axiomatisations
