Modern multimedia applications have a complex set of Quality of Service (QoS) requirements. On one hand, these applications define time, bandwidth and synchronization constraints and on the other are able to tolerate a non perfect communication service (i.e. a partially ordered and/or partially reliable service). However, current transport and network services do not fully satisfy these complex QoS requirements.
This work proposes a solution based on the design of a new QoS-oriented transport protocol (QoSTP) that aims to provide an extensive set of transport mechanisms intended to efficiently satisfy application requirements using available resources and network services. Furthermore, QoSTP was designed in the framework of a general QoS context providing an extensible semantic namespace and a compositional architecture. Its design aims to facilitate the specialization and enhancement of QoSTP to satisfy a growing number of applications while taking into account a large number of underlying communication services.
The design of QoSTP follows the Unified Development Process methodology based on UML 2.0. This methodology proposes three modelling stages: the definition of a global context, the definition of technical requirements, and the structure and behaviour specification using UML 2.0.
This presentation includes an introduction to UML, the contextual and requirement models of the proposed solution and the UML 2.0 specification for the transport protocol.
