Abstract
The use of Internet as an ubiquitous communication platform puts a
strong demand on service providers regarding the assurance of multiple
service levels consistently. Designing flexible and simple
service-oriented management strategies is crucial to support
multiconstained applications conveniently and to obtain a
deployable and sustainable service quality offer in multiservice IP
networks. In this context, this paper proposes the use of a
self-adaptive QoS and SLS management strategy sustained by a
service-oriented traffic admission control scheme to ensure the
negotiated quality levels. A proof-of-concept of the proposed strategy
is provided, illustrating its ability to self-adapt and control
efficiently distinct QoS requirements in multiservice IP networks.
