Main Components Codec library – implements basic coding and decodingalgorithms for text-based protocols Coder/Decoder configuration files – provide configurationparameters for Codec library XML format TTCN-3 type information Regular expressions for decoding Encoding patterns Manual Codec in Java/C++ Very few (e.g. approx. 3% of LibSip types)T3UC, Beijing8-10 June 2010
Benefits of the Architecture Development simplification Define regular expressions + encoding patterns No need for intensive Java/C++ development Extensibility of the test suite No Java/C++ coding to extend codecs for new types Maintainability of the test suite Re-define regular expressions + encoding patterns Little probability of re-compilation if TTCN-3 test suitechanges Test system robustness Only few codecs require Java/C++ programmingT3UC, Beijing8-10 June 2010
