Flexible QoS Support in DVB-RCS2

چکیده
Satellite is considered a vital technology for enabling ubiquitous access to broadband services in many countries. This paper explores provision of IP-based broadband satellite access with Quality of Service (QoS). It analyses a set of example scenarios, based on the recently published DVBRCS2 standard involving web and voice traffic. It specifically explores the interaction between Bandwidth-on-Demand (BoD) and QoS, showing that this interaction offers the flexibility required for satellite Internet service operators to manage the bandwidth of broadband users in a multi-service access network.

Evolution of satellite communications: Integration of ETSI BSM and DVB-RCS for future satellite terminals
The main added value of the European Telecommunications Standards Institute broadband satellite multimedia (ETSI BSM) architecture is the definition of the Satellite Independent-Service Access Point (SI-SAP) protocol interface, which formally separates Satellite Dependent (SD) from SI layers, thus enabling the implementation of powerful vertical QoS mapping strategies. On the other hand, DVB-S2...

The specifications of Digital Video Broadcasting Return Channel via Satellite (DVB-RCS2) state that the satellite gateway could introduce both random and dedicated access methods to distribute the capacity among the different home users. Before starting an engineering process to design an algorithm allowing to combine both methods, it seems necessary to assess the performance of each. This pape...
