dominating internetworking protocol of our times (IP), has been a challenge for
many researchers in the past years. Strict qualitative guarantees have proven
difficult to provide in a way that has discouraged efforts in the area. The lack of
a coherent provisioning methodology has been identified as the main reason for
this. In this work, we are attempting an analytical yet straightforward approach
to the provisioning methodology proposed for premium service of high-quality
demanding traffic in the wide-area. Our approach is based on a series of wellknown
results of queuing theory but is proven to provide good approximations
to experimental results as well as worthwhile qualitative guarantees.1 aBouras, Christos1 aSevasti, Afroditi  uhttp://telematics.upatras.gr/telematics/publications/analytical-approach-and-verification-diffserv-%E2%80%93-based-priority-service?language=el
