Systematic design of a network gateway using FDT LOTOS
Luís Ferreira Pires, Jeroen Schot · 1991
The design and partial implementation of a network gateway (an intermediate system) using the formal description technique (FDT) LOTOS are described. The requirements capturing process and the formalization process that results in an abstract and formal description of the gateway are described. This description is then refined through a series of functionality decomposition steps. It is claimed that the use of an FDT can improve the quality of the design and implementation, by allowing early evaluation of correctness of design steps.>
