Achieving End-to-End QoS in the Next Generation Internet: Integrated Services over Differentiated Service Networks
ABSTRACT
Currently there are two approaches to provide Quality of Service (QoS) in the next generation Internet: An early one is
the Integrated Services (IntServ) with the goal of allowing end-to-end QoS to be provided to applications; the other one is the
Differentiated Services (DiffServ) architecture providing QoS in the backbone. In this context, a DiffServ network may be
viewed as a network element in the total end-to-end path. The objective of this paper is to investigate the possibility of
providing end-to-end QoS when IntServ runs over DiffServ backbone in the next generation Internet. Our results show that
the QoS requirements of IntServ applications can be successfully achieved when IntServ traffic is mapped to the DiffServ
domain in next generation Internet.
