A Scalable Framework for End-to-End QoS Assurance in IP-Oriented Terrestrial-GEO Satellite Networks

The exponential growth of the Internet, the
heterogeneity of networks, and the need for QoS
maintenance have urged researchers to develop
ideas for managing network scalability and endto-
end QoS assurance. In this article an IP IntServ
architecture in the satellite access network is
combined with a scalable IP DiffServ-like architecture
in the terrestrial core network. The proposed
architecture aims at guaranteeing
fine-grained bandwidth control in the satellite
access network and stateless scalability in the
core network, by exploiting per-aggregate traffic
flow control, typical of the Aggregate RSVP protocol,
and stateless service assurance, typical of
the SCORE approach.
