Detailed Description

This component receives MntData objects, and randomly drops the objects.

Objects that are not dropped are pushed to subsequent components.

The dropping is done according to a two-state Gilbert model. When the current state is GOOD_STATE, the received object is not dropped. If the current state is BAD_STATE, the received object is dropped. The state switches randomly everytime a packet is received according to two probability values (good-to-bad probability and bad-to-good probability).

MntRTPDropper::MntRTPDropper (  float  p, float  q, int  seed )

Construct a new MntRTPDropper object in good state. Parameters: p  The good-to-bad probability. q  The bad-to-good probability. seed  The seed to be used for random number generator.

Member Function Documentation

void MntRTPDropper::recv (  MntData *  data  )  [virtual]

Receive some data, and push the data to subsequent components iff this component is in a good state. This object then checks if it should switch state according to the given probability. Reimplemented from MntComponent.
