Abstract
Session 2 - Satellite NGN QoS issues
Speaker: Stéphane Combes, Research & Development, Alcatel Space
Abstract
In Next Generation Networks (NGN), packet network technologies will have to support any type of real time
services (voice, multimedia,…) and will a fortiori require advanced QoS (Quality of Service) management
capabilities such as:
- QoS aware network equipment
- Admission control mechanisms
- Interaction between call signaling, resource management and admission control
As far as satellite based systems are concerned, especially those that include sophisticated resource
management features in order to use a shared user access such as DVB-RCS, no architecture nor mechanisms
have been defined or recommended by standardization bodies. The provision of an end-to-end QoS based service with a
satellite access is thus largely undefined and will eventually lead to system specific or proprietary solutions.
The presentation will highlight the challenges, possible architecture trade-off’s and standardization work recommendations.
Biography
Stéphane COMBES (stephane.combes@space.alcatel.fr) graduated from the
Ecole Nationale Supérieure des Télécommunications (ENST), Paris, France, and EURECOM Institute, Sophia- Antipolis, France,
in 1995. Since 1997, he has been working in Alcatel Space, Toulouse, France, where he is presently a research engineer
in the R&D department. He has been involved in various multimedia satellite projects involving GEO or LEO satellites
using conventional transparent payloads or more advanced On-Board Processing
techniques: internal R&D projects (ANIS, SkyBridge), ESA programs (DOMINO2, Amerhis) or IST projects (Brahms, SatIP6). His areas
of interest include satellite access layer definition (MAC, DAMA, Congestion Control, CAC design), QoS management & ground
segment architecture.
