AQM-BDG-in-NS3

Implementation of AQM Algorithm in 5G-AN RLC Queue Based on NS-3. An end-to-end congestion control scheme includes AQM based RLC queuing delay guarantee

The contributions of AQM-BDG can be summarized as follows:

*Achieving queuing delay guarantee of RLC queue through AQM algorithm in RLC buffer.

*AQM-BDG extends the granularity of QoS control so that SDFs mapped to the same DRB can obtain the corresponding throughput share according to the preset priority.

*An ECN marking system that can implement source rate regulation through packet header marking.

*AQM-BDG ensures that the RLC buffer queuing delay does not exceed the preset threshold, while almost fully utilizing the allocated resources in highly time-varying wireless links.
