FDT ==>
Formal Description Technique
<specification, protocol> (FDT) A formal method for developing
telecomunications services and protocols. FDTs range from abstract to
implementation-oriented descriptions. All FDTs offer the means for producing
unambiguous descriptions of OSI services and protocols in a more precise and
comprehensive way than natural language descriptions. They provide a foundation
for analysis and verification of a description. The target of analysis and
verification may vary from abstract properties to concrete properties. Natural
language descriptions remain an essential adjunct to formal description,
enabling an unfarmiliar reader to gain rapid insight into the structure and
function of services and protocols.
Examples of FDTs are LOTOS, Z, SDL, and Estelle.
[ISO/IEC DTR10167: "Guidelines for the application of Estelle, LOTOS and SDL"].
