ABSTRACT
Integrated Services (IntServ) and Differentiated Services (DiffServ) are two of the current approaches to provide
Quality of Service (QoS) guarantees in the next generation Internet. IntServ aims at providing guarantees to
end applications (individual connections) which gives rise to scalability issues in the core of the network. On the
contrary, DiffServ is designed to provide QoS to aggregates, and does not suffer from scalability. It is therefore,
believed that the combination of IntServ at the edge and DiffServ at the core will be able to provide QoS
guarantees to end applications.1, 2
Although there have been several proposals on how to perform mapping
of services between IntServ and DiffServ, there hasn't been any study to quantitatively show the level of QoS
that can be achieved when the two networks are connected. The objective of this paper is to quantitatively
