Questions on LAN trace output.

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

Hi,

I did a following LAN testing:

	0      2       4     6
        ----+------+------+-----+-----LAN
            1      3       5     7

The connection is created from node(0) to node(3), node(0) sends tcp 
packets to node(3). Here is the first part of the trace output in "out"

h 0 0 8 tcp 1000 ------- 0 0.0 3.0 0 0
h 0.002044 3 8 ack 40 ------- 0 3.0 0.0 0 1
h 0.00316 0 8 tcp 1000 ------- 0 0.0 3.0 1 2
h 0.00316 0 8 tcp 1000 ------- 0 0.0 3.0 2 3
h 0.005044 3 8 ack 40 ------- 0 3.0 0.0 1 4
.....

Node(8) seem to be the "virtual" LanNode. And the trace only monitors the 
packets sent to this "virtual" LanNode. As:
	node(0) send tcp pkt to LanNode 	(actually send to node(3))
	node(3) send ack pkt to LanNode 	(actually send to node(0))
	node(0) send tcp pkt to LanNode		(actually send to node(3))

My question is what "h" means here? Is there a queue setup for monitoring 
enque, deque, reveive and drop? I attached the source code and out file for 
detail information.

Any help is appreciated!
