Our method starts with the SDL specification of a protocol stack. We first derive a data and control flow dependence graph from each SDL process. Then, in oeder to perform cross-layer optimizations we combine the dependence graphs of different SDL processes. Next, we determine the common path through the multi-layer dependence graph. We then parellelize this graph wherever possible which yields a relaxed dependence graph. Based on this relaxed dependence graph we interpret different optimization concepts that have been suggested in the literature, in particular lazy messages and combination of data manipulation operations. Together with these interpretations the relaxed dependence graph can be used as a foundation for a compile-time schedule on a sequential or parallel machine architecture. The formalization we provide allows our method to be embedded in a more comprehensive protocol engineering methodology.
