— We define an analytical approach and a methodology to determine the set of Service Level Agreements (SLA) that can be effectively supported by a DiffServ IP network. We consider the Assured Forwarding (AF) Per Hop Behavior (PHB), and, based on the SLA probabilistic description, we derive a worst-case mathematical formulation for the over-booking(More)
— We focus on the identification and definition of " Web user-sessions " , an aggregation of several TCP connections generated by the same source host on the basis of TCP connection opening time. The identification of a user session is non trivial; traditional approaches rely on threshold based mechanisms, which are very sensitive to the value assumed for(More)
This paper focuses on the definition and identification of "Web user-sessions", aggregations of several TCP connections generated by the same source host. The identification of a user-session is non trivial. Traditional approaches rely on threshold based mechanisms. However, these techniques are very sensitive to the value chosen for the threshold, which(More)
