Our experience in interoperability assessment (since 1996) and in using the TTCN-3 standard allowed us to develop a tool (called ttproto ) that helps in: (i) experimenting new concepts for long term evolution of the TTCN-3 standard  and (ii) facilitating new approaches and methods for interoperability assessment. For instance, new passive approaches (see  ,  ,  ) that we developed have been implemented and validated using ttproto . This tool ttproto has been used to develop test suites for 6LoWPAN-ND (IPv6 for Low Power Networks) and CoAP (Constrained Application Protocol). The CoAP test suites have been successfully used for two Plugtest interoperability events organized by ETSI, IPSO Alliance and the FP7 PROBE-IT project, respectively 28-29 March in Paris (see  ) and 28-30 November in Sophia-Antipolis. The tool ttproto and the test suites indicated above are freely available at http://www.irisa.fr/tipi .
