Detailed Description

SatLlc base class holds the UT specific SatBaseEncapsulator instances, which are responsible of fragmentation, defragmentation, encapsulation and decapsulation.

Encapsulator class is thus capable of working in both transmission and reception side of the system. The SatLlc base class holds base pointers of the encapsulators, but the actual encapsulator types depend on the simulation direction:

At GW:

Encapsulators are of type SatGenericStreamEncapsulator or SatGenericStreamEncapsulatorArq
Decapsulators are of type SatReturnLinkEncapsulator or SatReturnLinkEncapsulatorArq
There are as many encapsulators and decapsulators as there are UTs within the spot-beam.

At UT

Encapsulators are of type SatReturnLinkEncapsulator or SatReturnLinkEncapsulatorArq
Decapsulators are of type SatGenericStreamEncapsulator or SatGenericStreamEncapsulatorArq
There is only one encapsulator and one decapsulator

Fragmentation is not allowed for control packets, thus the basic functionality of just buffering control packets without encapsulation, decapsulation, fragmentation and packing is implemented to the SatBaseEncapsulator class.

SatLlc is a pure virtual class, thus it is not supposed to be instantiated. A proper version of the SatLlc is inherited: SatUtLlc at the UT and SatGwLlc at the GW. There is no LLC layer at the satellite.
