Left Shift Operator <<

Silly me, I did not realized that the code:-

size << 3 is actually similar to size*2^3 or size * 8

The size in bytes are converted to the number of bits. I solved the flaw when the VBR generic traffic source transmit higher than the defined maxrate parameter.

Next plan to code call admission into MIRAI-SF3.1 network simulator. So far I have not seen any free source code on the Internet. For the time being, I have to reviewed some literature on call admission to get the basic idea.
