{
if ((buffer.Remaining > 0) && (_removeByteProbability > _rng.Next(1000)))
{
if (log.IsInfoEnabled)
log.Info(buffer.GetHexDump());

int pos = _rng.Next(buffer.Remaining);
// how many byte to remove ?
int count = _rng.Next(buffer.Remaining - pos) + 1;
if (count == buffer.Remaining)

for (int i = 0; i < pos; i++)
newBuff.Put(buffer.Get());

while (newBuff.Remaining > 0)
newBuff.Put(buffer.Get());
newBuff.Flip();
// copy the new buffer in the old one
buffer.Rewind();
buffer.Put(newBuff);
