Description
The objective of this activity is to design, implement and test active queuing management and packet scheduling techniques at the user terminals and ground equipment, so that the SATCOM network continues to provide seamlessly an acceptable throughput and latency to users under any congestion situation.Targeted Improvements:- Enabling a responsive and fair SATCOM network in any traffic andresources availability situation.- Keeping the additional queuing latency below 20ms (an order of a magnitude vs state of the art)per flow in any situation for both user terminals and gatewaysDescription: In SATCOM networks, tail drop queuing is commonly used,however it is not the best option since only two out of the following three qualities can be achieved: (1) high throughput, (2) small and bounded latency and jitter range, and (3) no service outage. Quality of service could be improved, and all three elements achieved with Active Queue Management (AQM) adapted for radio resource management of satellite communication networks. This will particularly benefit voice and video conferencing over satellite.This activity will adapt the design and test active queuing management and packet scheduling algorithms, fulfilling the above mentioned three qualities. The algorithms shall ensure seamless acceptable throughput and latency among the users and achieve additional queuing latency below 20ms per flow in any situation. They shall be agnostic of orbits. The targeted solution will time bound the packet latency by dynamically adjusting the bandwidth distribution among all users, considering the type of traffic in order to minimize degradation of all user quality of service. A test bed will be developed, and promising algorithms will be implemented and tested. Testing of the most promising one shall also be conducted over LEO and MEO satellite emulated channels.Procurement Policy: C(2) = A relevant participation (in terms of quality and quantity) of non-primes (incl. SMEs) is required. For additional information please go to:http://www.esa.int/About_Us/Business_with_ESA/Small_and_Medium_Sized_En….
