Modeling of TCP behavior in a DiffServ network supporting assured forwarding PHB
Rafał Stankiewicz, Andrzej Jajszczyk · 2004
The paper presents a mathematical model of the TCP behavior in a DiffServ network and its empirical validation. The assured forwarding per hop behavior is modeled. The model is modular - individual components of DiffServ nodes are described by separate sets of equations. It makes it easy to develop a model of a system consisting of various types of DiffServ node elements (meters/markers, shaper/droppers) just by changing some of the equations. The input traffic is divided into several traffic aggregates each having a part of a bottleneck capacity dedicated to it.
