To support various multimedia applications, the IEEE 802.16 standard defines four specific types of service flows (UGS, rtPS, nrtPS, BE) that meet different user requirements.
Each connection between a subscriber or a mobile station (SS or MS) and a base station (BS) is identified as one service flow by the connection ID.

Redirect Output Information into a File
You can redirect output information into a file and open it with any editor with this command (example):
./waf --run scratch/myfirst > log.out 2>&1
The log data is one of the ways to harness data from ns-3 simulation and only provide least amount of information.
The other ways to harness data from ns-3 simulation is through trace file data and topology animation.
The topology animation will confirms the topology visually and all the data will be in trace file data.

Regression
When a feature stops functioning as intended after some kind of of change to the system is integrated, it is called regression. Originally the term regression referred to a change that caused a previously fixed bug to reappear, but the term has evolved to describe any kind of change that breaks existing functionality. There are many kinds of regression that may occur in practice.
