Hey, so no one replied to your Q yet.  I don't know what you mean by RDT3.0.  Also, by trace I assume you  mean traceroute?  Also, the garbled packets, what do you mean by that?  If they are corrupt, there might be a network error.  Perhaps you can try a packet sniffer, ie: ethereal.  If you can provide a bit more detail, I think it will be helpful in getting your question answered.

The RDT3.0 is Reliable Data Transfer protocol version 3.0 and the trace is something like a graph which has Sender on the left represented by a vertical line and Receiver on the right with another vertical line, showing the status of sender and receiver while sending/receiving packets, SEQ number, ACT number, Timeout scenarios, etc. The garbled means the transitions of sender and receiver at various possible states.

I think what you want is a packet sniffer.  I would recommend Ethereal (http://www.ethereal.com), which is free and easy.  You put it into promiscuos mode, and then start you're normal traffic.  It will capture all of the packets, and you can sort or filter it by RDT3.0.  Should be able to give you a good analysis of what is going on with your data as it is being sent.
