  Backhauling services through satellite systems have doubled between 2012 and
2018. There is an increasing demand for this service for which satellite
systems typically allocate a fixed resource. This solution may not help in
optimizing the usage of the scarce satellite resource.
  This study measures the relevance of using dynamic resource allocation
mechanisms for backhaul services through satellite systems. The satellite
system is emulated with OpenSAND, the LTE system with Amarisoft and the
experiments are orchestrated by OpenBACH. We compare the relevance of applying
TCP PEP mechanisms and dynamic resource allocations for different traffic
services by measuring the QoE for web browsing, data transfer and VoIP
applications.
  The main conclusions are the following. When the system is congested, PEP and
layer-2 access mechanisms do not provide significant improvements. When the
system is not congested, data transfer can be greatly improved through
protocols and channel access mechanism optimization. Tuning the Constant Rate
Assignment can help in reducing the cost of the resource and provide QoE
improvements when the network is not loaded.
