Urgent, please help! TCP "packetSize_" definition

["Laura-Lei Liu" <liul@nortelnetworks.com>]

Hello,

I have a question on definition of TCP packetSize_. In the following default
parameter for each TCP agent:

Agent/TCP set packetSize_ 1000          ;packet size used by sender (bytes)

Does packetSize_ in this case mean:
-  payload only, not including the TCP header? Or
-  the total TCP packet length of payload plus header?

I am assuming this dows not include the IP header length. Am I correct?

Please help me on this. Thanks a lot!
