The initial purpose of this paper was to design a case study to assess LOTOS-T [MFV93] which is a temporal extension of LOTOS developed within the ESPRIT II OSI95 project. However, we think that it can be useful for any proposed timed FDT. It consists of a protocol composed of two entities and an underlying service provider, whose behaviour is mainly based on various timing constraints such as time-out, isochronism, rate-control,... The selection of the mechanisms was guided by the two following characteristics: Realism: the selected mechanisms have been inspired by similar and existing protocol mechanisms or service facilities, even if we have tried to (over)simplify them in order to focus the case study on the timing constraints. Temporal modelling facilities: this means that the specificity and the variety of the timing constraints are intended to assess whether timed FDTs have enough power and flexibility to tackle a maximum number of aspects of timed behaviours. Of course, we do not pretend to have explored all possible timed behaviours which may exist in protocols. We have simply tried to cover a broad spectrum of them. [less ▲]

The new communication environment has brought new requirements on the qualities of service for which the present "best effort" semantics is inadequate. The response to this evolution goes through the definition of a new model of QoS for the lower layers. In the Òbest effortÓ model, when a service provider accepts a transmission with a given QoS, it does not commit itself to any duty about the way it will take account of this QoS. The "guaranteed" QoS requires resources reservation mechanisms which are not always available. We present in this paper a new semantics for the QoS. It allows a service user to express more accurately its requirements, and although it does not include yet a concept of guarantee of the result, the fact is that it assures the users that the provider will monitor the selected parameters and return some defined feedback about the way it succeeds in meeting their requirements. New negotiation rules have also been specified, which are consistent with the new semantics. An example illustrates the practical use of the notions we have introduced which are at the origin of the OSI95 transport service. [less ▲]

On the Provision of a Fast Connect Facility in a Connection-Mode Transport Service

in The OSI95 Transport Service with Multimedia Support (1994)

A "fast connect" facility in a connection-mode service allows the calling service user to send service data units without waiting for the rount trip delay associated with the successful establishment of ... [more ▼]

A "fast connect" facility in a connection-mode service allows the calling service user to send service data units without waiting for the rount trip delay associated with the successful establishment of the connection. In this paper we investigate how such a fast connect facility can be added to a connection-mode transport service. Starting from the eXpress Transfer Protocol (XTP) which is at the origin of the concepr, we analyse the High Speed Transport Service (HSTS) and study how it can be improved by the introduction of a listening interaction at the called side. After having criticized these two transport facilities, we finally propose three possible models of the fast connect facility. The first one is the 4-primitive connection establishment from the Broadbant Transport Service (BTS) and the last ones are two 3-primitive connection establishment. [less ▲]

Useful measurement techniques for comparing soil structure resulting from conventional cultivation and no-tillage

Different tillages including conventional and minimum tillages were conducted over several yers on a loamy soil, in Gembloux (Belgium). Numerous soil properties were measured to evaluate these tillage practices on soil structure, workability, aeration, biological behaviour, ... with the final aim to establish the mechanisms to improve the yields and the economical returns of a given crop. The paper presents results concerning measurements of dry bulk density, soil structure and microrelief. [less ▲]
