The LOTOS Specification of the Enhanced Transport Service

چکیده

This paper introduces the LOTOS specification of the OSI95 Enhanced Transport Service. It discusses the problems encountered during its writing, such as the ones caused by its validation, or by the lack of a 'Timed' LOTOS. But the interest is not only in the specification itself. It also lies in the way this specification was developed: not after, but in parallel with the design of the Service it had to describe. The reasons for the choice of this way of working, its advantages (and drawbacks) are presented.

Specification and Validation of Multimedia Protocols using RT-LOTOS

The paper presents a new Formal Description Technique , RT-LOTOS (Real-Time LOTOS) which is a temporal extension of the standard Formal Description Technique LOTOS. After a brief and informal introduction to RT-LOTOS, the paper describes a design method of multimedia protocols based on the use of generic and reusable RT-LOTOS speciication building blocks. An application in the area of multimedi...

Template-Based Specification in LOTOS

The notion of a skeletal specification is introduced as a step in the incremental development of a specification. This leads to the idea of a template specification as a means of capturing specification architecture in a library of reusable specification components. The approach is illustrated by considering the architecture of service specifications in LOTOS. A library of macros written in the...

An Enhanced Version of Timed LOTOS and its Application to a Case Study

We propose here ET-LOTOS, a timed extension of LOTOS. It is an enhancement of Timed LOTOS that we presented at FORTE 92. We show how some simple modifications allow us to improve the expressiveness of our former formalism. To assess ET-LOTOS, we apply it to the specification of a small case study. Finally, we show how the semantics of ET-LOTOS could be modified to easily define more powerful op...

Specifying Hardware Timing Characteristics with ET-LOTOS

It is explained how DILL (Digital Logic in LOTOS) can be used to specify and analyse hardware timing characteristics using ET-LOTOS (Enhanced Timed LOTOS), a timed extension of the ISO standard formal language LOTOS (Language of Temporal Ordering Specification). Hardware component functionality and timing characteristics are rigorously specified and then validated. As will be seen, subtle timin...

RT-LOTOS and Its Application to Multimedia Protocol Specification and Validation

The paper presents a new Formal Description Technique , RT-LOTOS (Real-Time LOTOS), which is a temporal extension of the standard Formal Description Technique LOTOS. After a brief introduction to Basic LOTOS, the main time-related operators of RT-LOTOS are detailed step by step on small examples, and then formalized (RT-LOTOS operational semantics). The second part of the paper shows the applic...
