today?s networks has concentrated a lot of research and
implementation efforts. Particular interest exists for the
exploitation of the DiffServ framework towards the
provision of qualitative services in MANs and WANs
worldwide. Although individual mechanisms have been
widely investigated, not many references to studies
combining all levels of priority and QoS provisioning
exist. This work aims at presenting a thorough and
unified approach to the dimensioning and provisioning of
a high priority service for high-quality demanding traffic
over a MAN/WAN environment. Our approach anticipates
for bounds in specific quality metrics and is demonstrated
by the experimental case-study of a high-priority service
over a MAN topology.1 aBouras, Christos1 aSevasti, Afroditi  uhttp://telematics.upatras.gr/telematics/publications/deployment-diffserv-based-priority-service-manwan-environment
