Architecture of Satellite Internet for Asia-Wide Digital Communications
نویسندگان
چکیده
This paper describes the network architecture of an Asiawide satellite Internet that considers the situations in developing regions. The design considerations for the architecture are costs, effective use of satellite bandwidth, scalability, and routing strategy when combined with terrestrial links. The architecture includes using one-way shared satellite links to reduce costs, IP multicast to leverage the broadcast nature of satellite links, QoS, audio-video application gateway to adapt to the limited bandwidth of satellite links. This architecture is implemented in an operational network testbed connecting 13 countries and supporting a distance learning project.

Role of the Globalization of Communications (Internet and Satellite) on Young Womenâs Leisure Time (Case study: Young Women in Mazandaran)
Today, leisure time is changing by globalization and using of information technology. Most of people especially women prefer to spend their leisure time by modern technologies. Thus, they spend their leisure time to look up satellite programs and use of the internet. This research has done for sociological consideration of the globalization of communications (internet & satellite) on leisure t...
متن کاملPower Amplifier Linearization Using Six-port Receiver for DVB-S2 Satellite Communications
A digital look-up table adaptive predistortion technique using a six-port receiver for power amplifier linearization is presented. The system is designed in Ka-band for a DVB-S2 satellite link. We use a six-port receiver at the linearizationloop in place of classic heterodyne receivers. The six-port receiver is implemented by the use of passive microwavecircuits and detector diodes. This approa...

متن کاملEvaluation of Ad-Hoc and Mobility Architectures using Satellite Communications
In military or emergency scenarios (like Disaster Relief), the area where the terrestrial forces are located is not always easy to cover. In such an area, no infrastructure is available (never deployed or unavailable due to disaster for instance), persons are located in many locations, eventually structured in groups, but distant from one to another. The topology may also introduce difficulties...
متن کاملQoS Architecture over DVB-RCS satellite networks in a NGN framework
Geostationary satellite networks are currently considered as one of the most promising broadband access network technology for narrowing the digital divide. Though technically attractive and cost effective, the provisioning of endto-end QoS services in satellite access remains largely undefined. In order to bridge this gap, the European SATIP6 project defines a complete QoS architecture involvi...
