ConclusionConclusion
PATN provided the realistic data-link infrastructure PATN provided the realistic data-link infrastructure required for PD/3required for PD/3
PATN contributed to the validation of the ATN protocol PATN contributed to the validation of the ATN protocol suitesuite
The quality of service provided by the mobile The quality of service provided by the mobile subnetwork is critical for the perceived quality of ATN subnetwork is critical for the perceived quality of ATN services: AMSS did not perform as expected at the time services: AMSS did not perform as expected at the time of PD/3of PD/3
The PATN components and infrastructure can be The PATN components and infrastructure can be successfully built-upon by the partnerssuccessfully built-upon by the partners
