Ambiente para especificação de aplicações multimídia com suporte de qualidade de serviço.
Abstract
This work describes an environment for specification of distributed
multimedia applications with demanded Quality of Service (QoS) detailing.
The description of the application is made in a hierarchic way, in the
user, application and resource level, adding the demanded QoS parameters and the
adaptation rules to be applied for the Quality of Service monitoring/ (re)negotiation.
These rules and QoS parameters will be responsible for the activation of
the system adaptation to guarantee its execution in compliance with the Quality of
Service negotiated in the specification.
After the specification phase of the distributed multimedia system, the
environment generates the documentation in a specification language of system with
QoS detailing and its adaptation/ (re)negotiation forms.
This documentation feeds NIST Net emulator, allowing that the results
can be analyzed by the verification of the multimedia system behavior and the emulated
system.
