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.
