A Simulation Study of QoS for TCP Over LEO Satellite Networks With Differentiated Services

Tags:
quality of service

Overview A number of satellite communication systems have been proposed using GEOsynchronous (GEO) satellites, Medium Earth Orbit (MEO) and Low Earth Orbit (LEO) constellations operating in the Ka-band and above. The next generation broadband satellite systems will use fast packet switching with onboard processing to provide full two-way services to and from earth stations. Currently, Internet Protocol (IP) only has minimal traffic management capabilities and provides best effort services. This paper presents broadband LEO satellite network QoS model and simulated performance results. In particular, the paper discusses the TCP flow aggregates performance for their good behavior in the presence of competing UDP flow aggregates in the same assured forwarding.

Dutch bring satellite plans crashing down to earth

EU transport ministers voted the project E200m (£124m) in development funds, but whether it is to come to fruition will depend on private sector funding. The system will allow users to track their locations to an accuracy of one metre, using a...

VoIP primer: How it works - and what the jargon means

VoIP and packet switching makes for a more efficient use of network resources. But IP, of course, was not designed to provide a guaranteed quality of service (QoS) to the traffic it carries; it was originally designed as a way of diversely routing...

Inmarsat readies for mobile push

The company has launched four generations of satellites into the Earth's orbit since it was set up in 1979 and is currently looking for a launch window to fire its final fourth-generation satellite in the next 18 months.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
