31 Ventura, Joao Rodrigues, Joao Rodrigues, Luis 2001 4th IEEE International Symposium on Object-Oriented Real-time Distributed Computing (ISORC2001) Magdeburg, Germany IEEE 335-342 02/05/2001 0-7695-1089-2 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. http://doi.ieeecomputersociety.org/10.1109/ISORC.2001.922857
