Re: [EToSat] [QUIC performance and SATCOM]

[Emmanuel Lochin <[e-mail]>]

Dear Joerg, Tom,

If you attempt to mimic a satellite link with Netem or Dummynet, you 
might be interested in having a better emulation system such as OpenSAND 
: http://opensand.org/
If you need to be convinced by the capabilities of OpenSAND, check this 
paper : "Making Trustable Satellite Experiments: an Application to a 
VoIP Scenario" available here : http://oatao.univ-toulouse.fr/21907/
