Re: Token Bucket Filter Bug - Please help me

Syam,

The token bucket filter should drop a packet if qlen_ equals
zero and there are insufficient tokens to send the packet.
Are you certain that the 2nd conditions is satisfied?  That
is, is your source generating packets fast enough to use 
up all the tokens?

Hi,
I am using a token bucket filter in ns-2.1b5. I set the queue length of the 
filter to zero. As per the code in file tbf.cc, it is supposed to drop packets 
if queue length (qlen_) is set to zero. I do not see any packet drops. Please 
help me if I was doing any mistake or if some one was awre of the problem. Any 
suggestions will be appreciated.
Thanks in advance.
Regards,
Syam
