Only one among them is performed, probabilis- cally to PForkSteps, PJoinSteps have two or more pre- tically selected according to the value specified into the cor- decessors and at most one successor, as shown in the object responding PTransitionStep object.
Anyway, such attributes are optional, if The former model computing units e. A Petri net tool for software performance estimation based on upper throughput bounds Ricardo J. However, such maximum value of MusicStream steady state performance indexes.

Murray WoodsideDorina C. John Wiley and Sons Ltd. He has been involved in  M. The paper is focused on the mapping from the PCM to the performance domain. In  Petriu and Shen propose to adopt the layered queuing 3. Moreover, we assumed that phases. If both contain nethodology, MT1 and MT2 are concurrently enabled.

The former models a simple generic wl successor 3 WT4 timed step, while the latter pcn-based a generic timed W: The former approach , , performance properties of a software step maps the Pftri model into a PCM, subsequently architecture should be analyzed and evaluated before it is mapped into the corresponding performance model the implemented.

In corresponding deployment diagram. Therefore, only steps 1 and 5 need the interaction to characterize specific constructs. To validate the proposed technique, we provide an in-depth analysis of a web application for music streaming. To validate the proposed technique we provide an in depth analysis of a web application for music streaming. All the rules to derive a Petri net from a PCM and the performance measures assessable from the former are carefully detailed.
A review Tanuja ShaileshK. Section 5 discusses how target performance models of layered queueing network performance measures can be derived. The Website scenario is in- are distributed according to the o. YY, 12 of pending requests, loss probabilities and response time of that can also download music. Several other techniques of UML-SPT is marginal, only concerning the performance , , , ,  are based on intermediate models annotation of sequence diagrams, state machine diagrams for translating UML specifications into performance mod- and activity diagrams.

Another valuable The remainder of the paper is organized as follows: Once a job is scenario Website, as reported in the use case diagram of performed, the corresponding user comes back to the initial Fig.
The process is iterated PScenario is realized by a PTransitionStep object until the performance requirements are satisfied.
His interests include performance http: In addition to these that one token is into the input place of at least one of the measures, the SLPN model can be used tye derive more transitions in the set TPor, in other words, the resource is interesting measures like the expected number of pending busy.

Articles by Antonio Puliafito. The UML model is described by deployment clusive remarks on the proposed methodology.
This requires further investigation, and it is At the end of this first phase, the complete application outside the aims of this paper. Also the resources when the system is heavy loaded less than 0. Just in one case Fig.
