31 Rodrigues, Joao Miranda, Hugo Ventura, Joao Rodrigues, Luis 2001 6th IEEE International Workshop on Object-Oriented Real-Time Dependable Systems (WORDS2001) Rome, Italy IEEE 261-268 08/01/2001 0-7695-1068-X This paper presents the design of RT-Appia, a framework for the development and implementation of configurable real-time protocol stacks. The goal of RT-Appia is to allow the construction of specialized protocols through the composition of pre-defined micro-protocols. RT-Appia attempts to balance the flexibility and efficiency of microprotocols with the predictability requirements of real-time applications. http://doi.ieeecomputersociety.org/10.1109/WORDS.2001.945139
