Satellite and next generation networks: proposal for QoS architectures (original) (raw)

Broadband satellite systems will need specific functions and interfaces in order to fit seamlessly into an endto-end Next Generation Network (NGN) Quality of Service (QoS) architecture. This paper will define NGN overall architecture, showing how the coupling between Application/session layers and Network/transport layers can achieve end-to-end QoS support. Possible integration scenarios of satellite access into such architectures will be depicted, with a special emphasis on transparent and regenerative satellite architectures based on DVB-RCS [14] type of access.
