QoS‐oriented traffic management in multimedia satellite systems

The next generation of satellite systems will likely use some on‐board switching techniques enabling the direct transmission of data from any up‐link spot‐beam to any down‐link spot‐beam. If the switch used in the payload of the system is an ATM‐based shared buffer switch, some losses and delays can occur. Fortunately, these drawbacks can be fought thanks to some buffer management policies (HSPO, SMXQ, EPD) that either ensure low delay or low loss ratio.
