    Describes the restructuring of multi-perspective requirements specifications to facilitate the identification and analysis of inconsistencies and the management of change. A partial, heterogeneous and reasonably large requirements specification from a NASA project is analysed and decomposed into a structure of viewpoints, where each viewpoint encapsulates partial requirements of some system compon...

  • Experiences with the PEPA performance modelling tools

    Publication Year: 1999, Page(s):11 - 19

    The Performance Evaluation Process Algebra (PEPA) language is supported by a suite of modelling tools which assist in the solution and analysis of PEPA models. The design and development of these tools have been influenced by a variety of factors, including the wishes of other tool users to use the language for purposes which were not anticipated by the tool designers. In consequence, the suite of... View full abstract»

    Video-on-demand (VoD) is a service that has received much attention recently and the concept has become popular with computer and communication companies. Basically, VoD consists of a video server, interconnection network and user display equipment (UDE). It provides a similar service to the neighbourhood rental store. Videos or movies are distributed from the video server to users upon request th... View full abstract»

  • The Unified Modelling Language and performance engineering

    Publication Year: 1999, Page(s):2 - 10

    The use of performance analysis and prediction techniques by software designers and software engineers is at best inconsistent and at worst simply does not happen. This is principally because these techniques are seen as separate and difficult to apply. Work on software performance engineering, initiated by C.U. Smith (1990), has sought to bridge the gap but has had limited success. With the emerg... View full abstract»

  • SWAP, a performance evaluation tool

    Publication Year: 1999, Page(s):21 - 26

    Presents a simulation-based workbench for predicting the performance of distributed applications. SWAP (Simulation Workbench for distributed Application Performance) is based on providing end-users with mechanisms to specify the essential characteristics of the application being designed and the ability to match the software components with the operational environment (hardware and operating syste...

  • PNiQ: integration of queuing networks in generalised stochastic Petri nets

    Publication Year: 1999, Page(s):27 - 32
    Cited by:  Papers (6)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (484 KB)

    Generalised stochastic Petri nets (GSPNs) and queuing networks are combined at the modelling level by defining Petri nets including queuing networks (PNiQ). The definition is especially designed to allow approximate analysis by aggregation of the queuing networks and replacing them with GSPN elements. Usually the aggregation of combined GSPN and queuing network models is carried out manually, whic... View full abstract»

  • Differential QoS and pricing in networks: where flow control meets game theory

    Publication Year: 1999, Page(s):39 - 43
    Cited by:  Papers (25)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (404 KB)

    This paper looks at ways of providing quality of service (QoS) to users, based on a simple pricing scheme. It is primarily aimed at elastic traffic, and it is users rather than the network who define the flow control schemes. A framework for assessing schemes and algorithms via a distributed game is presented View full abstract»
