The paper presents a generic framework to analyse the timing behavior of protocol graphs derived from the composition of micro-protocols. The model assumes that a protocol stack is composed of a set of protocol objects that interact through the exchange of events. A specific task is associated with each relevant protocol event and for each task, the periods and offsets are derived from a description of the interactions between adjacent protocols. To illustrate the use of the model, a stack of modular reliable group communication protocols for the CAN field-bus is analysed.
