    Yet another bugfix + code to call a function that sends NSESWAP event · ac01c40b
    Shashi Guruprasad authored
    when it cannot keep up with real-time.
    
    bug: This affected encapsulated simulator packets that had to cross
    multiple physical nodes before arriving at the destination simulator
    traffic agent. This bug didnt affect live packets from traffic sources
    on real PCs.
    
    The NSESWAP event is now sent via the tevc command. The nse scheduler
    waits for the slop factor (diff between clock and event dispatch time
    that exceeds a threshold) to be crossed multiple times in a second
    before sending the NSESWAP event. Currently 5 times in 1 second.
    However, this needs more careful thought and will get modified later.
    When is it really necessary to declare that an nse is overloaded?
    i.e. what is the right slop factor? How many times can we tolerate
    that the slop factor is exceeded to ensure end-to-end performance
    is within a certain percentage of the expected?
