High Quality Media Streaming over Longdistance Network Using FELIX Experimental Facility
This demo paper presents the FELIX project [1] approach of implementation the "High Quality Media Transmission over long-distance networks" use case. A virtual slice built on demand over European and Japan infrastructure allows to perform the experiments and shows capabilities of the test-bed and its availability for high quality media streaming experiments over a long distance federated network. It is also the first time when the FELIX Control Framework is used for provisioning the SDN resources for the experiments. Two experiments for use case implementation and validation in the FELIX test-bed are proposed and described.
A conceptual design study titled Deep-space Optical Terminals was recently completed for an optical communication ::: technology demonstration from Mars in the 2018 time frame. We report on engineering trades for the entire system, ::: and for individual subsystems including the flight terminal, the ground receiver and the ground transmitter. A point ::: design is described to meet the requirement for greater than 0.25 Gb/s downlink from the nearest distance to Mars of ::: 0.42 AU with a maximum mass and power allocation of 40 kg and 110 W. Furthermore, the concept design addresses ::: link closure at the farthest Mars range of 2.7 AU. Maximum uplink data-rate of 0.3 Mb/s and ranging with 30 cm ::: precision are also addressed.
