You have got it wrong. Let me explain.

r 40.639943 _1_ AGT --- 1569 tcp 1032 [a2 1 2 800]  ------ *[0:1 1:0 32 1] *[35 
0] 2 0.

Here above,

r = received
40.639943 = time it was received
_1_= receivind node number(means the packet was received at node 1)
AGT = means transport layer(I think)
1569 = unique packet id(each packet has a unique id)
tcp = Transmission Control Protocol
1032 = packet size
a2 = packet lifetime(I think)
1 = MAC address of sender
2 = MAC address of receiver
800 = 802.11 wireless
0:1 = means node 0 (i.e. address is 0) and port is 1 of sender
1:0 = means node 1 (i.e. address is 1) and port is 0 of receiver
32 = TTL

There are lot of books online, download them, they are free and look up 'Trace 
Format'
