    Analysis of the use of DVB-RCS Resource Assignment Mechanisms for Internet Traffic.
    (2012) Chafla Altamirano, Gustavo Xavier; Chafla Altamirano, Gustavo Xavier
    This paper presents the simulation results of a satellite network based in the Digital Video Broadcast Standard for the outbound channel DVB-S and the return channel DVB-RCS for interactive satellite terminals called RCST. The network model was built under the Network Simulator NS and the main objective was to study the return channel DVB-RCS resource request mechanism and adaptation layer for carrying BE Internet traffic and real time flows. An approach that use rate based (RBDC) requests for traffic with quality of service requirements, and volume based (VBDC) requests for best effort traffic is proposed and evaluated for a corporate scenario that offers services such as voice over ip VoIP, videoconferencing and web surfing.
