Abstract

This paper analyzes several mitigation strategies and techniques that could enable delay sensitive applications to work properly over satellite IP networks. A study is conducted on different satellite classes (GEO, MEO and LEO) and the analysis of the current solutions for real-time interactive appli-cations is performed. The great distance from Earth results in an important RTT, which is the main aspect to consider for real-time interactive applications. To date, the multi-layered architecture seems to be the best way to go, since it overcomes the drawbacks of the single layer approaches. This, in turn, creates traffic balancing and quality of service concerns that are also discussed according to the proposed solutions.

Satellite Internet access

Satellite Internet access or Satellite Broadband is Internet access provided through communication satellites. Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using to achieve downstream data speeds up to 506 Mbit/s. In addition, new satellite internet constellations are being developed in low-earth orbit to enable low-latency internet access from space.

Voice over IP

Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for voice calls, the delivery of voice communication sessions over Internet Protocol (IP) networks, such as the Internet. The broader terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of voice and other communications services (fax, SMS, voice messaging) over the Internet, rather than via the public switched telephone network (PSTN), also known as plain old telephone service (POTS).

Satellite phone

A satellite telephone, satellite phone or satphone is a type of mobile phone that connects to other phones or the telephone network by radio link through satellites orbiting the Earth instead of terrestrial cell sites, as cellphones do. Therefore, they can work in most geographic locations on the Earth's surface, as long as open sky and the line-of-sight between the phone and the satellite are provided. Depending on the architecture of a particular system, coverage may include the entire Earth or only specific regions.
