Status-Oriented Telephone Service Specification: An Exercise in LOTOS Style
نویسندگان
چکیده
The authors and other members of their group have already written some papers and research reports on specifying telephone call processing in LOTOS. Two such papers, where two differently organized specifications of the Plain Old Telephone System service (POTS) were presented, were [FLS 90][FLS 91]. The specification in the second paper was mainly in the constraint-oriented style, while the one in the first was in a combination of constraint-oriented and state-oriented style. We are now presenting yet another style of specifying telephone systems, because we feel that this new style has some definite advantages over the ones used in previous papers. In particular:

Formal Specification of Telephone Systems in LOTOS: The Contraint-Oriented Style Approach
The LOTOS constraint-oriented style allows the design of wellstructured, implementation-independent specifications of distributed systems. As an example, we provide a small, didactically-oriented specification of a simple telephone service. The design of the specification is based on three types of constraints, i.e. global constraints, end-to-end constraints and local constraints. The structure...

At interaction point c, the environment can provide the number of a new instance of the station process. The next behavior expression consists in the new instance interleaved with the installer itself. We have presented a style of LOTOS specification based on synchronization between processes to exchange status information. This style takes full advantage of the capabilities of the control part...

متن کاملAn Exercise in Protocol Veri
We present methods and tools for the veriication of behaviours of Lotos programs, based on the explicit construction of a nite automaton. We discuss a behaviour oriented style for Lotos that eases the construction of this model. We present the veriication tools integrated in the lite tool set, and illustrate the approach with the full speciication and analysis of a datagram protocol.
متن کاملConstraint-Oriented Specification of Performance Aspects
This note sketches how to extend (distributed) system specifications with performance constraints. The emphasis is on how to include performance aspects in a modular way. The key of the approach is to specify random delays as separated processes that are composed in parallel with an untimed, functional system specification. The use of parallel processes as separate constraints is in accordance ...
